Description

  The present invention relates to an electronic device storage rack that stores information communication devices such as servers, and more particularly, to an electronic device storage rack that can always visually check the temperature distribution inside the rack.

  With the development of information processing technology and communication technology, there are many cases where information communication devices such as servers and routers are highly integrated indoors. As a result, the interior of the electronic device storage rack that stores these devices is locally In particular, the high temperature portion tends to occur. The allowable operating temperature of the components that make up these devices is generally around room temperature. If the ambient air becomes hotter than this, the device itself automatically stops due to protection control, and services cannot be continued. May be destroyed, leading to failure.

For this reason, conventionally, a technique for monitoring a temperature in the rack by arranging a temperature sensor inside the rack and driving a circulation fan provided on the bottom of the rack to uniformly control the temperature is known (for example, patents). Reference 1).
However, the temperature distribution inside the rack is not uniform depending on the amount of heat generated by the electronic equipment to be stored, the storage position, and the like, and there is a problem that heat accumulation tends to occur. For this reason, an electronic equipment storage rack that can clearly grasp the internal temperature distribution has been demanded.

On the front surface of the rack 1, a door portion 3 for taking in and out the equipment is provided so as to be opened and closed by a hinge (not shown). Inside the rack 1, a server 7 is housed fixed to the frame rails 12a, 12b. The frame rails 12 a and 12 b are fixed to the frame portion 9. On the back surface side of the door portion 3, a plurality of control boards 4 are arranged at equal intervals in the left and right and up and down directions. Referring to FIG. 2, LED lamp 6 and temperature sensor 5 are attached to control board 4 in an integrated manner, and LED lamp 6 can be viewed from the outside through hole 3 a provided in door portion 3. It is configured as follows. As the LED lamp 6, two diodes capable of emitting red and green light are used.

  A power supply box 16 is installed at the bottom of the rack 1. A wire bundle 10 for power supply and signal transmission is wired between each control board 4 and the power supply box 16, and is configured to perform power supply and alarm transfer to the LED and CPU described later. An outlet 8 is installed on the lower side of the rack 1, and power is supplied to the power supply box 16 through the outlet 8.

Next, the configuration of the power supply and control system in this embodiment will be described. With reference to FIG. 3, the power supply and control system mainly includes a plurality of control boards 4 disposed in the door portion 3 and a power supply box 16 disposed in the rack 1.
