DC switches reboot upon voltage calibration!

[yahel]

Happened twice today, at two different locations:

Switch #1: WS-12-250-DC firmware 1.4.8rc6 Board Rev D, PS firmware 53, PS board Rev A
Switch #2: WS-12-250-DC firmware 1.4.8rc10 Board Rev F, PS firmware 53, PS board Rev B

At calibration, upon entering the measured voltage, the switches rebooted!

To add to the confusion, switch #1, when rebooted, kept the POE-output powered on - so no radios rebooted.
However, switch #2, upon reboot, switched off ALL outputs, and got everything to reboot!

Sad day!

PS - We have done calibration to many other switches without a problem before.

My bad - I copied the info about boards from a wrong switch...
Both switches have the same board revision F, and the same PS board revision B (and same PS firmware 53).

One has firmware 1.4.8.rc6 and the other 1.4.8rc10 - as I indicated above.

Thanks,

Yahel.

Yahel- have tested this feature extensively and not seen this behavior. Few questions:

Were you using the GUI or commandline?
Was it an immediate reboot, or was there a minute or so delay?
Can you drop to command line and run:

cmd
cat ../tmp/config/dc_multiplier

and get back to me with the output?

I recommend upgrading these two to 1.4.8 as a matter of course - will upgrade PS firmware from 53 to 58

Thanks,

Julian

We'll try to upgrade tonight.

There was a delay - if I had to guess, it was much shorter than a minute.
In other switches, where this reboot DIDN'T happen - the log reads "warm start" when we do the calibration.

Here's output from one switch:
admin@PALH-Netonix:/www# cat ../tmp/config/dc_multiplier
1.005
admin@PALH-Netonix:/www#

Here's the other:
admin@Bean_Netonix_(solar_12P):/www# cat ../tmp/config/dc_multiplier
0.995
admin@Bean_Netonix_(solar_12P):/www#

Thanks,

Yahel.

Have to confirm with Eric, but 'warm boot' populated in logfile is expected behavior as far as I'm aware.

Cutting PoE is not expected behavior - Do advise on results where firmware is upgraded to 1.4.8 final prior to calibration, please. Have so far been unable to duplicate in a controlled environment, will continue testing.

Thanks!

We've done a few more calibrations that went well.
Both to 1.4.8 and previous firmwares -- I know it's not helpful to you, but nothing more I can contribute....
Just hoping it would continue that way, and where possible we'll upgrade prior to calibration..

Thanks,

Yahel.
