I have above chassis error on hp n class .Looks like Fan 0 has failed .Anybody has anyclues on "How to disable the fan "

[Pete Randall]

I would say that your fan is already disabled and you should be trying to fix it instead.

But my machine reboots at least once a day .I dont know why.Plus can u let me know from where i can get the part number of the fan unit.

[manu_9]

my GSP Logs says SOURCE ID :0 and Source id : 3 FOR FAN FAILED .But stm says fan 6 has failed ......i am confused

[Chris Vail]

If a fan has failed, and the system reboots, this is probably due to an overheat condition. The logs will show this.

Get that fan fixed and/or lower the air temperature where the N class is. My rule for any server any where is that inlet temperature should never be above 80 degrees F. When inlet temperatures climb to 85, I start shutting down systems. At 95 degrees, the system is likely to fail all by itself, so its better to do a controlled shutdown.

If you can't get the proper fan installed, just get standard floor fan (the more powerful the better) and force air through the front of the cabinet. This will usually suffice until the tech rep shows up.

hi manu,

you should be able to see the status of all the fans and psu's in the gsp. i would be inclined to trust this first before stm. stm maybe just numbering them generally.
If your really cannot decide then just remove the covers one at atime on the server and check the led's green is ok and amber faulty. All the fans have them, just dont leave the covers off very long. If all fans are ok then you may have a problem with the power monitor board.

Hello Manu,


As per the chassis codes,fan 0 has to be replaced ,which is located in front side on the left hand side, if viewed the server from front .
