SG350X-24 switch overheating, shuts down ports under low stress

i have been recieving the following error on my SG350X-24 managed switch. it only occurs when we plug 2 devices into the switch's 10gbe ports (rj45, not sfp+), even when no data is being transferred over the 10gbe lines, the fans go from level 0, through 1-2-3-4 and then 5, followed shortly after by the following warning:

 

%Environment-A-ENV-MONITOR-CHNG: sensor 4 (Phy) temperature 99C .Temperature reached the critical threshold, All ports will be shut down in 2 minutes

 

the ports then shut down. the switch is cool to touch during this whole process.

 

switches are in a 25°C environment with good airflow.

 

i have two of these switches, linked together with an sfp+ cable. when i try the same test, but have 1x device connected to 1x rj45 10gbe port on each switch, instead of both on the same switch, there is no problem.

 

any ideas? i found another topic with similar reported issues with a SG500 a few years ago, looks like it was resolved with a firmware update, but i can't find any info about my switch in particular. https://bst.cloudapps.cisco.com/bugsearch/bug/CSCux37567/?rfs=iqvred

 

thanks!

This seems to be a bug in the 2.5.x code line.  I had the same issue after upgrading from the 2.4 code line.  Rolling back to the 2.4 line made everything happy again.

 - Switch temperature  does not correlate to network  traffic volumes on ports. Make sure the device is really in an appropriate operational environment concerning temperature.

I can confirm this is a bug.  Had to rollback firmware upgrade on a couple of them today because of this.  One of them was the only device in the rack in a 68F room.  At least on 2.5.0.83.

I'm looking into this switch. I have a couple of questions:

1. If the 10GbE RJ45 ports are not used (only the 1GbE and 10GbE SFP+ ports are used), how loud is the fan?

2. Some folks mentioned that when the 10GbE RJ45 ports are used, the fan gets very loud. Is this still true? Or has a firmware upgrade resolved this issue?

Same problem here.

Tried to make stacking with two 10 gbit RJ45 ports (three switches, ring topology). Swithes ran latest firmware - 2.5.5.47. Also tried 2.5.0.92. Fans get loud when two 10 gbit RJ45 ports are used. About 8500 rpm or so. Environment conditions are ok, switches are cold.

 

Downgrading to 2.4.0.94 resolved this issue, seems whole 2.5.X.X branch is still bugged.
