Switch s1500 12p operating temperature

[ Edited ]

Hello i was wondering if i should get worry when looking at this temperature of one of our swithces?

 

System Temperature : CPU Temp : 67 C
                                   : Mid Temp : 62 C
                                   : DPE Temp : 73 C

 

Does this look to high? for a fanless switch?

I can see on the datasheet that it says from 0 to 40 

 

It seems to be working fine and we just have 2 AP 225 connected to that Switch(which drain power) other ports are used for PCs.

 

Which would be the tempature trehoold  for S1500 12p switch?

 

I did find the controller ones here http://community.arubanetworks.com/t5/Controller-Based-WLANs/What-are-the-controller-temperature-thresholds-for-normal-minor/ta-p/178116

 

But not Switches ones.

 

Cheers

Carlos

Hi Carlos

Looks ok to me for fanless (not far off the temps of my 1500-24p which has a fan). Note that the 0-40 is the ambient supported, the temps you are seeing are localised at the temp sensors - will always be higher.

 

Not sure the exact thresholds - will try to track them down

Re: Switch s1500 12p operating temperature

hi Carlos

here are some more details from R&D

regards

-jeff

 

=================

 

Name               Threshold

-----------------   ----------------

CPU Temp         95 *C

Mid Temp           85 *C

DPE Temp         110 *C

 

These thresholds values are same for all MAS platforms/models.

 

System shutdown is triggered when CPU or DPE temperature crosses the above mentioned threshold values. Before shutdown there will be ‘syslog’ and ‘trap’ generated, along with ‘alarm’

 

Depending on the proximity of the current temperature to the threshold  value:

 

Minor alarm:   If temperature lies between (threshold – 15)  to  (threshold – 5)

Major Alarm:   If temperature lies between (threshold – 5) to  threshold.

Critical Alarm: If temperature is above respective threshold.  Then triggers shutdown.

 

And when the switch shutdown happens, it will NOT resume/auto-bootup post cooling. User has to manually cycle the AC power.

==================================================
