Catalyst 4510R stops responding.

Hello,

My 4510 switch stops responding over the weekend. No users in the office that day so no complains about conenctivity. I can't telnet to it, can't ping it. I can ping loopback0 but no telnet allowed though. CDP works fine, can see the switch from the directly connected neighbor switch. This morning local SA gets to the server room and reports all modules )8 of them) have no power. He reboot the device. Comes back up with no problems. Diagnostic clean, no errors currently reported. CPU history shows very high utilization on and before of the problem occurance. I have no outside log so no way I can see any errors. What would be the way best to approach this problem. I have set up local syslog server . The switch is running IOS 12.2(18)EW3, 512MB RAM, 64MB Flash.

Thanks for your help.

Raf

IOS 12.2(18)EW3 is a defferred release so the first then you should do is upgrade to 12.2(20)EWA3 or 12.2(25)EWA5

First of all thanks for reply. We have more than just one of 4500 series in that office and there is no problem with other switches. Our network is kind of lage, there is no easy way to do an IOS upgrade especially in case like this when only one device with a particular IOS has failed. This of course will be addressed in the next month or two. Currently colelcting log messages to the Syslog server hoping that I will catch some valuable data. Thanks

Possible causes of problem: a) software bug - if you detect something in syslog and call it in to Cisco the first thing they are going to do is to tell you to upgrade b) misconfiguration - post your config if you wish so group can take a lot c) hardware problem

I do not understand the comment about "no easy way" to do an upgrade

IOS used in our devices are standardized, new IOS must be approved by different group before. Thanks.

Well you probably should advise the group responsible that the standardization process that the IOS version in use is a deferred ( read junked ) release.
