Preferably, in the fan backboard of safeguarding on described support fan, in order better to judge that whether fan is normal, whether in operation process, break down, be provided with two LED lamps on each fan connector side, be used to refer to the operating condition of the fan that connects of corresponding fan connector, described PSOC chip is connected and is controlling the light on and off of the LED lamp of indicating fan-status with described LED lamp simultaneously.
Preferably, two LED lamps of corresponding described fan connector, are provided with two light-guiding pillars on described fan connector on the fan connecting, and the light of the LED lamp of instruction fan-status is exported to cabinet outside, conveniently the operating condition of fan are checked to maintenance.
Preferably, the fan backboard of safeguarding on described support fan is arranged on system top, on described fan backboard, offers several fixing threaded holes, by screw, described fan backboard is fixed on the cabinet sidewall of correspondence system fan.
Embodiment:
Below by an embodiment, a kind of design content and advantage of supporting the fan backboard of safeguarding on fan described in the utility model is elaborated.
A kind of fan backboard of safeguarding on fan supported described in the present embodiment, its structure as shown in Figure 1, on described fan backboard 1, be provided with eight fan connectors 2, PSOC chip 3 and back panel connector 4, described fan connector is for connected system fan, and corresponding each fan connector 2 is provided with the LED lamp 5 of two instruction fan-status, described PSOC chip is arranged on one end of described fan backboard, and described PSOC chip 3 is connected with described fan connector 2 and then is controlling the rotational speed regulation of fan on fan connector, described PSOC chip 3 is connected and is controlling the light on and off of the LED lamp of indicating fan-status with described LED lamp 5 simultaneously, described back panel connector is arranged on the side of described fan backboard, is plugged on system signal backboard by fan backboard described in described back panel connector, and described PSOC chip 3 is connected with described back panel connector 4 by the SMBus bus on described fan backboard simultaneously.
The logic diagram that accompanying drawing 2 is the fan backboard safeguarded on described support fan, as shown in Figure 2, PSOC chip on described fan backboard is all connected with described fan connector and LED lamp, is controlling respectively the light on and off of the rotational speed regulation of fan that described fan connector connects and the LED lamp of instruction fan-status; One, two LDE lamps of corresponding each fan connector be green light another be red light, in the time that fan running is normal, green light can be bright; In the time there is fan running fault, red light can be bright; Described PSOC chip is connected with described back panel connector by SMBus bus simultaneously, fan backboard is plugged on system signal backboard by described back panel connector, communicate alternately by iic bus (being connected with described back panel connector) with the BMC on described IO Riser, realize fan control.On the other hand, the power supply of the system fan on described fan connector, is powered to the system fan on described fan backboard by back panel connector by described signal backplane.
Described in the present embodiment, support the fan backboard of safeguarding on fan, transmitted the signal of controlling rotation speed of the fan by the iic bus of the BMC on described IO Riser, after described PSOC chip receives signal, decode, and the signal that sends corresponding dutycycle is to fan, controls rotation speed of the fan with this; Meanwhile, fan rotating speed signals passes to described PSOC chip, and PSOC chip monitors rotation speed of the fan with this to the BMC on described IO Riser by encoder feedback.When system is in operational process, need to safeguard fan time, fan is extracted, BMC on described IO Riser monitors less than rotation speed of the fan, judges that rotation speed of the fan is 0, as long as system temperature is no more than critical value, system just can normally be moved, and can realize fan warm connection function.
Use the fan backboard of safeguarding on described support fan, utilize PSOC chip to realize detection and the control of rotation speed of the fan; And need not open cabinet completely, only turn on the operational situation that the casing of fan top can be checked fan by fan-status pilot lamp LED lamp.In the time that fan running is normal, green light can be bright; In the time there is fan running fault, red light can be bright.And by the light-guiding pillar on fan structure, the luminous situation of LED lamp is exported to system top, greatly facilitate the diagnosis of fault position of fan, saved the time of dismounting cabinet.Owing to using this fan backboard to support fan hot plug, can constantly in the situation that, plug processing to fan in system, and can safeguard separately each fan respectively, and the system that do not affect is normally moved, support fan to carry out upper maintenance, improve the stability of system.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection domain of the present utility model.
