Zywall 1100 shutdown with overheat message

ChrisK

I have a Zywall 1100 at my datacenter with very controlled temperature. All fans are blowing. Suddenly I had several thermal shutdowns this week with no changes except firmware 4.65 installed. After removing all ethernet connections and using another ATP unit. The Zywall 1100 is staying up although no ethernet port connected.
Anyone have a clue ??

Hi, would you please share the temperature that you know is into the rack?

Hi @ChrisK,

Use the following commands to get information about the temperature of the processor (CPU) and the system board (System Board). Values are presented in degrees Celsius.

Router> debug hardware

Router (debug hardware) # fan-get

Here is the suggested temperature of operating environment for your reference

Maybe Fan0 has an issue. Still don't understand thermal errors.
Thoughts
The datacenter has a hot zone back and a cool zone front.
the hot zone is typicaly mid 80's F / Cool zone is 70ish or better.

Hi @ChrisK,

If the system halted/shutdown because of overheat, the SYS LED will turn Red.

If your ZyWALL 1100 is still online, connect console and follow the video to keep collecting console logs.

If the device halted again because of overheat, monitor the status of SYS LED and send the console logs to me in private message.
