Switch no responding every night

[tribord]

hi everyone,

i hope someone could help me, this is an customer issue.

i have 4 switchs, but no stack,  SG200-50p with 1 PoE. On the PoE there are servers, routers and other switchs.

every morning i need to reboot my switch PoE because the network is not reachable. when i reboot it, the network is good.

Firmware Version:     1.4.8.6

Boot Version:     1.3.5.06

i attach last log from RAM Memory.

don't worry, the system date is not correct

thank for your help

There's nothing attached may have failed to upload but sounds like a bug you could wait for new release or roll back a version see if it fixes it 1.4.1.03

Thak for your answer,

i can install an older version with the last firmware ?

PS : there is attachement now :)

[Mark Malone]

that log only contains start up information nothing that indicates why it failed unfortunatly

You should be able to roll back to 1.4.1.03 no problem theres no upgarde path between them , if the issue still persists after that you may have to look at replacing the hardware if its under support board may have an issue and its resetting itself to recover from malfunction

out of interest is it at a specific time each night ? have you checked the usual before changing software the electrical connections going to the switch or moved it to another section to make sure its not that , or that no one is disconnecting it by accident each night i.e cleaners , sometimes it can have nothing to do with teh switch itself or cehck if its on ups thats not interfering with it somehow

Hi

If you have contract or warranty you should open a case with the Cisco TAC to verify this unusual situation.

Yes i know,



But they ask me to send us switch and after they will send me an another switch.



I can't do that



My customer need to work et i have only one switch PoE

I understand, they usually send a new switch and once it is received you send the failed one. They could create the RMA process for this switch. This situation is  not usual it looks like a kind of bug or it could be a problem with hardware.
