Catalyst 3500 Problem

just realized I posted this in wrong section, so here it is:

Hi here is my problem:

I have 2 3500XL switches in a building exhibiting problems. I am having multiple instances of link up/down state changes. Sh post tells me ports 9-12 failed loopback test as well as the Gigabit port 1. No one in the building can data out. I am able to telnet in from another route though. This happened last week on about Thursday. Just prior to this we had a pretty bad storm blow over, lots of lightning. I am thinking Electrostatic Discharge and the interfaces for both are damaged. However I can't justify that, any help would be appreciated. If I had to replace them thats fine I just want to know I have exhausted all my solutions first.

Sincerely

Brandon C McHenry

Re: Catalyst 3500 Problem

If the switch failed POST, it is bad hardware. Get it replaced.
