Hello everybody. I'm very happy finding this Site.

I'm a systems technician with a great problem with a Cisco 3500 XL.

The switch received a mains overvoltage and the power supply's primary condenser burned....

I repaired it and check that the 5 and 12 volts in the secondary were OK, but when i connected to the cisco 3500 mainboard only ports leds 1 and 2 were lighting. The system does not start and i can not see any activity in system console.
The 3,2 volts supply in the mainboard does not have output. I tried to power it with an external 3,2 volt supply but i have not response..

Any ideas or service manual ?

Thanks.

Hello,

At the moment I do not have solution.
It does not appear any type of boot message or additional information by the console.

It is dead !!! :?

Thank You!!

When you power on the switch, do the POST tests run?
Do you see any status lights lighting and what color are they?
Look at this section of the article I mentioned earlier if it helps:

If your switch doesn't pass POST then you better call Cisco Systems for assistance
Keep us updated,
Cheers
