reboots on its own

reboots on its own

reboots on its own

this is an ip office which randomly reboots and we can't see why. config has been checked and reloaded, psu has been changed, ip office has been changed, ip office is now on a ups, environment is air conned [cool] and no interference nearby [eg copier, large screen vdus etc] : any ideas?

RE: reboots on its own

When running the monitor application using the correct tick box's for system reboot you should be able to search the txt file for either cause codes (BT errors other than 16/17 normally 127/79/65/38  ) or search for contact lost. These will show you when the system reboot, one classic is the customers LAN , if they run SNMP  queries (The lan administrator has set up all the monitoring tools on the network).

TRy to get the customer to run a sniffer at the same time this would normally show details as well, to assist you in finding the problem, check the amount of network traffic on the LAn as well.

Therer is not just one reason why this happens but one reason from a list, sorry its over to you.

Get an electrian to check the power sockets, it may be "unclean" or you have something like a compressor nearby

RE: reboots on its own

Don't know if you have resolved this issue but one possible cause is if you have a large paging group defined for the switch. We discovered that the reboots were occurring at the time of messages being paged. We had one install where this was an issue and Avaya provided a patch specifically to deal with this problem.  No problems with reboots since.

RE: reboots on its own

I have an IPO 406 Doing the same thing.  Ive replaced 1 30 port module and also the IPO 406 module itself.  System is located in a rack in an air conditioned environment.  Isolated power with Isolated ground.  
Im starting to get use reboots with this system.  
What a nightmare!!!

RE: reboots on its own

From my experience the majority of system reboots are caused by either incorrect programming of the switch or a particular set of circumstances that highlight a bit of buggy code.

IPOJedi is right to suggest that the monitor application is the way to go forward, particularly looking for contact lost sections in it which are followed by contact made and a very short uptime in ms.

It would also be worth leaving a laptop connected to the serial port, saving all output to file as this may catch something useful that doesn't get output to the monitor file.

I would be happy to look at any saved monitor file for you to help get your problems resolved.

RE: reboots on its own

There is currently and issue with Phone30 modules rebooting. A patch is due out shortly to rectify the problem. A monitor trace will indicate whether the IPO is rebooting or whether calls a dropping ie. due to a module rebooting.
