BCM 450 fan Alarm

[7upp]

I recently install a 450 5.0. I continue getting fan1 alarm. I replaced the fan, which didn't resolve the alarm. I've watched the fan when the alarm comes on and it appeares to working fine. Any suggestions would be appreciated.

Thanks in advance Don

Could it be one of the other 2 fans?
Not sure Fan1 point to which one, you have 3, on the CPU,in the PSU and the rear one.

Hi Don, I have the exact same issue, I get a critical fan1 alarm, recovers exactly 5 minutes later each time. What was the resolution?

Thanks, Jeff

Having the same problem with my new 450 5.0 that I am getting ready to install. Do I need to send it back for repair or is there a patch.

I am including information from a case I opened last year. I was getting the same alarms and Nortel fessed up to shipping the wrong fans. Please read below:

-------------------------------
We are currently experiencing an issue with the fans that are shipped from Nortel and included in the BCM450 Redundancy upgrade package. This package is actually shipping with BCM400 fans, these fans are not compatible with the BCM 450 Hardware.

Please confirm that this if you are having a reduncdancy kit that came with the BCM 450.
If yes, please provide me the part numbers of the reduncdancy and the 450.

Thank you.

I just seen a patch for this problem. They have increased the time before the fan brings up a alarm. I was checking on a 32+ red led issue that I have had with the last two BCM 450 that I installed.
Hope this helps Don

you need the patch

 

[joebocc]

thanks bditech
do you know where i can download the patch from?
i am still working with the networking section for a site setup for the bcm. they are holding back to make sure the system is working properly and not causing system slowdown with all the critical alarms. i now get at least 10 in a 24 hour period.

You can get the patch right off the Nortel website. Should be the latest bcm450 update.

I had this problem last spring with an install, and the patch did as promised. I wished I'd had updated prior to the install.
