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.
