Dell PowerEdge 2650

Medium Priority

I have a Dell PowerEdge 2650 that is no longer under warranty and I have a Fan #4 that has failed. I had to reset the button on the back of the server to get the server to boot up. I don't want it to crash again. Looks like I have 7 fans in this box (see below)
The fan is not reading right now, it has a big red "X" in the Dell Open Manager software. I am not sure what to do with this. Any help would be greatly appeciated.  Thanks, Kathy

Try swapping the fan with another in the box to make sure it is just the fan.  If it is, replace it.  If the error stays in the same slot, then you have a bad motherboard slot (which can occasionally be fixed by updating BIOS and ESM firmware).

I do have the latest BIOS,  not sure about the ESM firmware. I will try swapping the fans and checking the ESM firmware. Thank you!

I suggest the ESM because it is the device that is actually responsible for managing fan speeds and reporting.  Generally, as the BIOS and ESM are inter-dependent, they should be updated together to prevent a number of strange issues that can arise.  Good luck.

It's almost certainly the fan in my opinion, only because the motherboard doesn't have moving parts and fans ARE moving parts.  Definitely follow PowerEdgeTech's diagnostic instructions, but I'll be surprised if it's the motherboard.

If by chance it does turn out to be the motherboard, you can potentially get a similar fan and hook it into a standard power cable or another relatively standard/common power source.  It won't read properly from the motherboard, but it should help keep things cool and ensure the system continues to run in a stable manner.  (This is not ideal, but if you insist on using an old server, it may be the best option - again, IF it's the motherboard, which it probably isn't)

Thank you, I think I will order a fan and just replace it, sounds like that would be less downtime right now.

Fans are hot-swappable, so replacing the fan won't require downtime, but removing more than one at a time is not supported (although I've done this with non-processor fans without issue, I wouldn't recommend it in this scenario).  As it is almost always the fan (although I've seen the board connector go bad or simply need a reseat on these too), simply ordering another would involve no downtime to replace it.

Hi,
I have a couple of questinos, I brought a cooling fan and when I open the server I could not tell which fan is #4. Also I have two bigger fans near the back of the server, what are these used for?  How do I tell which fan I need to replace.

thank you, :)

The fan locations are labeled on the board - not very large, but they are there.  It is the rear fan for processor 1.

Commented:
So I guess I got the wrong size fan, I ordered the little one, OK back to order the processor fan.

Commented:
I am seeing that both the Dell P/N 8J202 Fan & 5J294 Processor Fan Assembly are the same and my question is that the two fans near the back are a lot wider then the fans near the front of the server. Is there another part number for the fans?

Oh dear! This is my fault I'm afraid.   There are two entries in my Dell Spares list for the fans:

P/N 8J202 Fan & 5J294 Processor Fan Assembly
P/N 5Y378  CPU Fan & 4Y364  Processor Fan Assembly

I think I've given you the front & rear part #'s not the smaller CPU fans which is what you actually need :(

Commented:
Whew, I thought I was losing it. Thanik you so much for this information, having a few extra fans for that old server can't hurt anyway.

Commented:
I did buy the fan but decided the server was to old to use so the server was replaced. Thank you!!!!
