Description
Technical Field
The present application relates to a computing server, a computer chassis, and an information providing apparatus. The present application also relates to one or more methods of using, configuring, modifying, repairing, servicing and updating the computing server, computer chassis and information providing device.
Background
Computing servers (also referred to as servers, computer servers, or server systems) have become increasingly popular and important in providing web services and modern network communications. The service information of the computing server is typically printed on a label affixed to the cover of the computing server. For example, service information on user removable units (CRUs) and Field Removable Units (FRUs) of a computing server is typically written on sticky labels as a guide to users and service technicians. However, expired tags are difficult to remove quickly and cleanly. Most manufacturers of computing servers often remove the entire lid with the labels affixed instead of using expensive, hazardous, and dangerous chemical solvents to clean out these expired labels. This wasteful manner of operation is still used by most computing server manufacturers and users worldwide.
Disclosure of Invention
The essential features of the application are defined by the independent claims, while the important or preferred features are described by the dependent claims.
According to a first aspect of the present invention, there is provided a computing server comprising a rack; an information providing device secured to the bracket, the information providing device including a socket. The receptacle is configured to removably receive a service information provider that provides service information for the computing server. The socket may be internal or external to the information providing apparatus.
The information providing apparatus may include a service providing tag and an information slide. The service information tag is removably secured to the information slide so that the information slide can be inserted into the receptacle to display the service information or removed from the receptacle to be replaced with another service information tag. Thus, the socket facilitates displaying service information on the label affixed to the slide. The information provider may alternatively include one or more storage devices, interfaces or connectors for receiving service information tags. For example, the information provider (e.g., information provider) includes a USB connector, wireless receiver, wireless transceiver, or other computing hardware interface for receiving the service information tag as a hardware copy or a software copy.
The rack is a framework for securing and protecting components of the computing server. The information providing device is alternatively referred to as a service information providing device because it can hold, store, or provide information for the computing server. The receptacle provides a slot, receptacle or holder capable of receiving an external component to the information providing device. In particular, the socket can accept or release one or more service information tags by a service technician. For example, an expired service information label may be removed from the outlet by the service technician and replaced with a newer service information label. In other words, the receptacle may be replaced with a service information tag. Examples of the service information tag may be a positive film, a negative film, a microSD card, a USB thumb disc, or any other device for storing the service information. Further, when covered or located internally, the receptacle may provide a sealed enclosure to prevent dust, moisture and bacteria from corroding the service information label. The provision of a protective cover, for example by the housing or a transparent sheet of the information providing device, makes it possible to extend the service information label in use with little or no degradation. In one embodiment, the receptacle is a drawer that is movable (e.g., inserted) into and out of the information providing device, such that the information providing device provides protection after the service information tag is inserted.
Since the information providing apparatus can replace the service information tag as required, the service information can be easily updated and fixed to the calculation server. It is no longer necessary to dissolve the glue of the old service information labels with harmful chemical solvents (e.g. toluene, rosin, acetone, methyl acetate, ethyl acetate), which often contain fire, explosion, environmental and health threats. In contrast, updated service information tags may be sent to users of the computing servers through normal low cost postal service, and the service technicians in the field may very easily, conveniently and safely replace expired service information tags with updated service information tags.
The information provider may be configured to accommodate permanent or rewritable service information tags. The permanent service information label provides service information on an opaque (e.g., paper), transparent (e.g., thin glass sheet), or translucent substrate (e.g., a projection sheet) so that the service information can be conveniently read by a service technician, either directly or via an intermediate tool (e.g., a magnifying glass). In contrast, the rewritable service information tag may be provided on a thermoreversible recording medium. The thermoreversible recording medium includes a reflective layer made of aluminum, an inversion heat induction layer, and a projection layer on a support (substrate or base). The heat sensing layer includes a resin (such as a propylene polyol resin) and an organic low-molecular compound having a glass transition temperature of-10 ℃ to5 ℃. Alternatively, the rewritable service information label may be provided on a rewritable laser medium including, in order, a projection layer, an ultraviolet-shielding layer, a recording layer including a photo-thermal material, an oxygen insulating layer, and a substrate. Expired service information on the rewritable laser medium may be erased by the rewritable laser, and the latest service information may be printed by the rewritable laser marker.
The information providing apparatus may further include an image enlarger for easily viewing the service information on the label. The image magnifier is an optical device that can magnify a picture of the service information label. For example, the image magnifier includes a magnifying glass and an magnifier made of glass or transparent plastic. Illustratively, the amplifier is formed by one or more polycarbonate fresnel lenses.
The image amplifier may further include an image projection device that projects the service information on the tag. The image projection apparatus includes a high-speed projector, a slide projector, and an opaque projector. The image projection means causes the service information tag to be projected on a distant screen to be viewed enlarged. Therefore, instead of a large sticker on which the service information is printed, the service information label is made in a small piece (e.g., 5 mm. about.5 mm). The service technician may place a blank a4 sheet as a temporary viewing screen at a distance from the image projection device. The service information can thus be easily read onto the screen. If larger text messages are also desired, the service technician may simply move the screen a bit further away from the image projection device to obtain a larger projected image for comprehension. Accordingly, the image projection device becomes a simple and reliable reading tool capable of presenting the service information in a scalable size. The service information label sheet may be inserted into a professional image projection apparatus as necessary, and thus, the service technician may read, print, scan, transmit, or store the service information off-site.
Instead of a spherical lens, the fresnel lens is more compact and easy to manufacture. The fresnel lens can also be made of low cost materials (e.g., shaped polycarbonate) that are also simple to process (e.g., cut or polished). One or more of the same fresnel lenses of different focal lengths may be further connected into special purpose lenses such as processing lenses, magnifying lenses and transfer lenses.
Although the information providing device may accept one or more external light sources for illuminating the service information label sheet, the information providing device may also include one or more internal light sources for illuminating the service information on the label. When an external light source is employed, the information providing device may have one or more openings and/or light guides (e.g., optical fibers or reflectors) for directing external light onto the sheet. For example, the information providing device has a hole with reference to the LED light bulb of a mobile phone, so that the service technician can light up the sheet by placing a turned-on LED light bulb of a mobile phone in the hole. If the one or more internal light sources are used, the information providing device can work independently, achieving optimized lighting and projection according to design planning. Both the internal light source and the external light source may operate independently or in cooperation.
The internal light source may comprise an LED (light emitting diode) bulb. The LED light bulb, also known as an LED lamp, has a long life, consumes less electricity, reduces cooling costs, requires less maintenance, is more durable and flexible to fit in a variety of design configurations. The information providing device can thus be made more compact, robust and low cost, without excessive expenditure on the cooling mechanism. In fact, since the housing of the information providing device can be made of a strong aluminum material, the housing can effectively dissipate heat from the LED light bulb, and can also firmly protect the internal components of the information providing device.
According to a second aspect, the present application provides a computing server comprising a rack; and a tag amplifier connected to the cradle. The tag amplifier is configured to removably receive a service information tag. The tag amplifier may alternatively be referred to as a tag amplifier that amplifies the image of the service information tag locally or at some distance. For example, the label magnifier includes a magnifying lens (e.g., a conventional spherical concave-convex lens or a fresnel lens) and an image projection device. The tag magnifier may increase the size of the image or text on the service information tag so that the service technician can easily and clearly read the image or text. In contrast, since the service information label can be made for indirect reading by the label enlarger, the service information label can have a smaller footprint (footprint) than those of conventional printed stickers. The tag amplifier includes any data or information storage device (e.g., microSD card) that can provide text or images on a larger Liquid Crystal Display (LCD).
In one embodiment, the tag amplifier comprises an image projection device providing an image of the service information tag at a distance from the image projection device or a computing server. The image projection device is compact, removable and of standard size such that the computing server can exchange the image projection device with other computing servers (e.g., from a voided computing server for the reusable portion).
According to a third aspect the present application provides a computer chassis of a computing server. The computer case includes a bracket to which information providing equipment is fixed. The information providing apparatus includes a receptacle operable to be removable for receiving a service information tag. The computer chassis or the rack includes a structure that supports hardware components of a computing server. For example, the computer chassis or the rack may include a backplane carrier, PCI plug members, a power box, a top cover mounting rack, heat sinks, memory card fills, fans, memory card cavities, RAID battery racks, DVD mounting racks, a front cover, a backplane cavity, or any other hardware portion of a computing server. The computer chassis or rack provides a reliable platform for mounting the information providing device and may further be possible to be a shared platform or exchanged with other computing servers.
The holder may comprise a support for holding the information providing device. The support may be a peg, spring, box, magnet or magnetic assembly. If the information-providing device has one or more magnet materials, the holder may include an electromagnet or a permanent magnet for locking the information-providing device to the holder. No external power supply or additional effort is required for maintenance when installing or using the holder.
The information providing apparatus may further include an image amplifier for amplifying the service information on the tag. The image amplifier may comprise an image projection means for projecting the service information on the label. The information providing apparatus may include one or more fresnel lenses for magnifying the service information on the label. The information providing device may include an internal light source for illuminating service information on the label. The internal light source may comprise an LED bulb.
According to a fourth aspect of the present invention, the present application includes an information providing apparatus for a computing server. The information providing device includes a connection device fixed to the computing server; and a socket for detachably receiving a tag having service information of the computing server. The connection device is a mechanical, electrical or mechatronic connector for permanently or removably securing the information providing device to the computing server. In effect, the connection device causes the information providing device to be mounted to a machine involving the tag. Thus, the information providing device can be sold separately for connection to any machine, with easy replacement of expired service information tags when necessary.
The information providing apparatus may further include an image enlarger for easily viewing the service information on the label. The information providing apparatus may further include an image projection device for projecting and displaying the service information on the tag. The image projection means may comprise one or more fresnel lenses for magnifying the service information on the label. The information providing apparatus may further include an internal light source for illuminating the service information on the label.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
By way of example, non-limiting embodiments of the present application will be described with reference to the above-described drawings.
Fig. 1 to5 relate to an embodiment of the present application. In particular, FIG. 1 shows a computing server 20 having an image projection arrangement 22, the computing server 20 including a stand 24, in addition to other components 26 of the computing server. Only a small portion of the computing server 20 is shown in fig. 1, and most of the other components 26 are not shown. Other components include cooling fans, Central Processing Units (CPUs), image processing units (GPUs), and random access memories. The bracket 24 includes a holder 28 having a slot 30 for securing the image projection arrangement to the bracket 24. The support 28 further comprises a supercapacitor 31, typically connected to a power supply unit (not shown) of the computing server 20. The supercapacitor 31 (also referred to as a supercapacitor or an electric double layer capacitor) is a large-capacity electrochemical capacitor having a capacity value of up to 10000 f at a voltage of 1.2V. The supercapacitor 31 has two metal foils (current collectors), each covered with an electrode material, such as activated carbon, as an electrical connection between the electrode material and the external terminals of the capacitor. The supercapacitor 31 has a much longer life than a battery. Although the image projection device 22 is shown floating above the bracket 24 in fig. 1 for clarity of viewing, the image projection device 22 is removably locked to the slot 28 of the bracket 24.
Fig. 2 shows a perspective view of the image projection arrangement 22. The image projection device 22 includes external components and internal components. The external components include a housing 36, a first fixture 38, a second fixture 40, a recess 50 for receiving an information slide 42 containing service information for the computing server 20, and a back cover 44. When inserted, as shown in FIG. 2, the informational slide 42 and the housing 36 are coupled to one another to form a water and dust tight sealed container 36. A first clip 38 is coupled to a top portion 38 of the housing 36 and a second clip 40 is coupled to a bottom portion 40 of the housing 32. A rear cover 44 is attached to the ends of the first clip 38 and the second clip 40 to seal their rear ends.
Fig. 3 shows an exploded view of the image projection arrangement 22. Fig. 4 shows a cross-sectional side view of the image projection arrangement 22 viewed from the direction of projection a display in fig. 3. Both views more clearly show the internal components 34 of the image-projecting device 22. The internal assembly 34 generally includes a light device 52 and a fresnel lens holder (not shown). In particular, FIG. 3 shows the rear cover 44 having an annular through hole 46 in the center. The information slide 42 is further inserted into a recess 50 in the housing 36.
Fig. 3 and 4 also depict the optics 52 of the image projection arrangement 22 in more detail. The optical device 52 includes an LED (light emitting diode) bulb 54, a condenser lens 56, and a projection lens 58, which are sequentially aligned from the rear cover 44. The LED light bulb 54 is closely fit aligned with the annular through hole 46 in the rear cover 44. A positive electrode 60 (anode) and a negative electrode 62 (cathode) extend out of the housing 36. The optical device 52 further includes a first leg 38, a second leg 40, and a back cover 44, as the inner surfaces 64 of the connectors 38, 40, 44 are polished and finished to a mirror or reflector 38, 40, 44.
The condenser lens 56 is a fresnel lens, and has a radius (denoted by symbol r) of 1.5 millimeters (mm) and a focal length (denoted by symbol f) of 3.45 millimeters (mm). The projection lens 58 includes a first fresnel lens 66 and a second fresnel lens 68 that are tied together back-to-back (see fig. 5). The fresnel lenses 56, 58, 66, 68 are constructed of a transparent polymer Polycarbonate (PC). Polycarbonate (PC) material has a refractive index (denoted by the symbol n) of about 1.58.
Fig. 5 illustrates the working principle of the image projection device 22. In detail, fig. 5 shows the focal length f of the fresnel lenses 56, 58, 66, 68 and the transmission image 72 of the service information label 48. The focal lengths of the fresnel lenses 56, 58, 66, 68 are substantially the same. The transmission image 72 is approximately three times the size of the service information label 48, and is approximately 16 millimeters (mm) from the second fresnel lens 68. The optical parameters of the image projection device 22 are determined by the following equations. In the equation, r1And r2(is represented by r)i) Respectively, the radii of curvature of the condenser lens 56 and the projection lens 58. Condenser lens 56 and projection lens 58 may have the same or different radii of curvature.
In the equation, the focal length "f" is a vector having a positive value (denoted by "+") if placed on the object side and a negative value (denoted by "-") if placed on the imaging side.
The image-projecting device 22 may alternatively be referred to as a pico projector, or a pico projector. The image projection device 22 transmits the magnified image to a location at a distance from the computing server or the image projection device. In contrast, the tag magnifier can not only magnify the service information tag image onto a remote screen, but can also display an enlarged copy near the service information tag, referred to as local. In contrast, the enlarged copy may enhance, clearly showing the brightness and clarity of the service information label. Furthermore, the tag amplifier may present a holographic image of the service information tag or have a high density holographic data storage. The holographic image may be dynamic or static.
When the information slide 42 is inserted into the housing 36, the information slide 42 and the housing 36 become a sealed enclosure so that external dust, bacteria or moisture cannot corrode the service information on the information slide 42. The service information slides are thus more robust.
The housing 36 and the rear cover 44 are made of a low cost plastic. In addition, because the interior surface 54 of housing 36 is a mirror finish texture, housing 36 is referred to as a good reflector for focusing the illumination light onto information slide 42.
The LED bulb 52 may be replaced by other light sources such as incandescent, halogen, arc lamps (e.g., xenon arc, mercury xenon arc, ultra high performance, ultra high pressure mercury vapor arc, metal halide), gas discharge lamps (fluorescent, compact fluorescent, neon, mercury vapor, sodium vapor, sulfur, electrodeless). The super capacitor 31 may be replaced by one or more batteries of various sizes.
In use, an electrical switch (not shown) on the bracket 24 is opened so that the supercapacitor 31 is charged. The LED light bulb 54 receives power from the super capacitor so that the service information label 48 is illuminated. The divergent light from the LED bulb 54 is focused from the condenser lens 56 to the projection lens 58 and becomes parallel light. Since the service information label 48 is a transparent sheet on which the service information of the calculation server 20 is printed, the service information printed on the service information label 48 is projected as a projected image 72 to the screen 74 with an opposite orientation to the service information label 48. The service information can be easily and clearly read from the screen 74 by a service technician (not shown). The screen 74 is a temporary flat panel from which a4 sheet is from a nearby copier.
