@RuNguyen​ probably i have the same issue...I have C6520 that are dropping the following log "The Inlet temperature is greater than the upper critical threshold."

Hello C.bryson,

I think this is the information you are looking for.

Standard operating temperature specifications:

C6400 : https://dell.to/3C5VYO7

C6525 : https://dell.to/3swcPGW

Hello,

I had currently purchase same unit C6520 our inlet always at 27 and 28C which trigger warning alert. How do you guys fix the issue? Just increase the threshold warning to higher? did you guys open ticket with Dell support and what you guys outcome. According to dell they said the inlet temp should be below 25C, which kind of very low as compare to all other dell poweredge servers

Dear all !
I have C6400 chasssis, but some node have inlet temperature max is 47 but some have 37. That node same bios version, idrac version.

Can i set same 47 for all nodes ? 
Thank you !

Has there been any fix for this yet?

Hello,

Could you let us know what system you have?

Do you have any image of errors you can post?

Is this something that just started?

Was anything done on the system around the time this started like any parts removed or installed?

Is the datacenter cooling sufficient? Has it had any issues?

Initially I could recommend make sure the system firmware is up to date to have any fixes they may have to be applied.

We are seeing this issue too in our C6500/C6525 systems, each has 2x64core AMD 7713 procs. Our firmware is up to date.  Is the high threshold set wrong on these?  

Hello,

What is the error you are seeing?

     Inlet temperature is greater than the upper critical threshold

     CPU temperature is greater than the upper critical threshold

Or another temperature error? An image of the error(s) may help.

When did the issue start and was anything done on the systems around that time such as hardware added or removed or updates applied?

Do you see any related errors in the System Event Log (SEL) you can share such as fan failures or other related errors?

Could you post the iDRAC firmware you are on?

If it is happening with all the systems; Is the datacenter cooling sufficient? Has it had any issues?

The threshold is set for most typical use, I don't know offhand what that is.

The iDRAC allows you some customization if you need to.

You may try some customization:

@DELL-Charles R​ Sorry for the delay.

We are seeing 'Inlet temperature is greater than the upper critical threshold' errors. There are no fan failures or any other hardware errors in the SEL.  IDRAC firmware is 7.10.30.00 (Build 30). This is happening on both of the units we own (we own 2), the temps are consistent across all 8 C6525s.  The ambient temp in front of these racks is reading 20C. We know this isn't ideal, but we expect the inlet temps to be in line with the incoming ambient temps and we don't understand how it's so high. 

Here is the temp output from one:

------------------------------------------
Main System Chassis Temperatures: Critical
------------------------------------------

Index                     : 0
Status                    : Critical
Probe Name                : Inlet Temp
Reading                   : 27.0 C
Minimum Warning Threshold : 3.0 C
Maximum Warning Threshold : 26.0 C
Minimum Failure Threshold : -7.0 C
Maximum Failure Threshold : 27.0 C

It seems odd that you are warned at 26C and it fails at 27C??
