Proliant Fan failure

We re-booted our Proliant 6000 this morning and the POST detected a failed fan, and went into a cycle of reboot/POST error/reboot etc. We can see the dead fan, and have placed support call with a 3rd party organisation to replace it.
But they are going to take a while to get the part and engineer to us. In the meantime, is there any way to persuade the machine to ignore the POST error and actually boot to the O/S?

Re: Proliant Fan failure


NO It will restart as soon as
Caution Temperature 57.3o C 135.14o F
Critical Temperature 80.7o C 177.26o F

Reason Why :

All current and some discontinued Compaq ProLiant Servers are equipped with thermal sensors called thermistors to monitor internal over temperature conditions. Thermistors are either discrete components mounted on the chassis near the front of the server or they are surface mounted components (integrated on a printed circuit board) located near the processors and I/O expansion slots. The temperature thresholds detected by the integrated thermal sensors can be programmable or hardwired. As a result, temperature thresholds during system boot (determined by the System ROM) may be different from thresholds that are reprogrammed ( by the Operating System Health Driver) during normal system operation. In the ProLiant 1500, 6000, and 7000
