Temperature for 5320-24p-8xe

jcrower — Wed, 19 Jul 2023 07:17:56 GMT

Hey all,

We have two 5320-24p-8xe stacked.

Doing a show temperature shows both switches as below:

Field Replaceable Units Temp (C) Status Min Normal Max
------------------------------------------------- --------- ------- --- ------- ---
Slot-1 : 5320-24P-8XE 69.32 Normal 0 10-100 110
Slot-2 : 5320-24P-8XE 67.88 Normal 0 10-100 110

Is this normal temperature considering they have just been installed and are not currently doing much? And Max 110 seems quite a lot (assuming it is celsius and not fahrenheit).

Our stacked Cisco 9300's which are doing all our layer 3 stuff run less than that.

thanks

Hi JC,

I have a local 5320-48T that is running about the same temp, mid 60s.

The temps are in Celsius, that is correct.
The highest 'normal' temp is 100C, the highest temp the switch will allow before it automatically shuts off is 110C.

There is always a tradeoff of how fast to spin fans versus how hot to let the switch get. There is no way to manually adjust the fan speed, the switch will automatically set a suitable fan speed based on active load, PoE load, temperature of various sensors etc.

As long as the temp is in the 'normal' range and your fans are not 'failed' in 'show fans', then you're good to go!

Hope that helps!

No worries, thanks @Gabriel_G,. Just wanted to be certain the temp limits were ok so I can adjust our monitoring systems accordingly.

Actually, some EXOS platforms allow you to tweak the fan speed, but that's more on the debug side I guess (debug hal configure forcefanpercent). There is no way of getting back to automatic fan speed unless you reboot the switch.

Temperature is measured at different points in different switches. Different vendors have different policies for reporting temperature. Some measure on a hot CPU, some air outflow, some on some other surface. In one DC, these switch models are placed in the same rack but show vastly different temperatures:

X690: 70°C

X696: 37°C (a few in the same temp range)

X870: 90°C (a few in the same temp range)

This one is interesting (switch and interface module):

Switch : 5720-48MXW 78.37 Normal 0 10-100 110
5720-VIM-2CE-1 : 31.62 Normal 0 10-100 110

All have 10-100 as their normal range. That's what is odd to me, not that the temp readings differ. Will the X695 still live if the temp goes up by 63°C?

Gabriel,

Can you share this info for a x450G2 and x460G2

You can check 'show temperature' to see operating temperature range on each switch.

Do you mean actual temperatures? Here are some more from select environments. All DC-type switches are in properly cooled locations, the access stuff may be in anything from good to whatever... Intervals are what I observed, not any sort of acceptable range.

X440G2-12p-10G4: 69-76 C
X450G2-48p-10G4: 77 C
X460G2-24t-10G4: 66C
X460G2-24x-10G4: 59-62 C
X695-48Y-8C: 38-50 C
X670V-48t: 38 C
7720-32C: 45-60C
5420F-24T-4XE: 65-75 C
5720-48MXW: 78 C
X350-24t: 37 C
X450a-24x: 39-42 C
X450e-48p: 40-45 C
X440-8p 32 C
X440-48p: 27-28 C
X460-48p: 20-27 C

As mentioned, the temperature may well be measured in vastly different places. Example:

Field Replaceable Units Temp (C) Status Min Normal Max
---------------------------------------------------------------------------
Switch : X440-48p 33.00 Normal -10 0-48 55

Normal is 0-48 and max 55. As you can see above, any X440/450/460-G2 will be over that limit, but they have this spec:

Field Replaceable Units Temp (C) Status Min Normal Max
------------------------------------------------------- --------- ------- --- ------- ---
Switch : X450G2-48p-10G4 77.00 Normal 0 10-100 110

So for them, it is normal with the ~77 C I observed.

Temperatures are measured in different places. It's like saying your car is too hot. Do you mean driver's seat, engine oil, coolant, washer fluid or the brakes?
