I'm using an IOGEAR GCS1732 KVM switch with a Sun Ultra 20 workstation.
The KVM is on the HCL list.

After connecting to the switch the Ultra 20 fails to boot up. On
powerup the fan spins for a few seconds and then shuts off but the
power light stays on. The system doesn't show any video or spin the
host drive.

Since I had Sun support, Sun sent a guy out who checked it and couldn't
find anything wrong. He chalked it up to a bad power supply, replaced
it, and the system came back up.

After a month, I reconnected the system to the KVM and it immediately
failed again.

Has anyone else seen this problem?

I put a console back on the Ultra 20 but it refuses to boot now, just
like before.

I would be inclined to believe that the KVM switch is defective!

It's hard to see how it could wreck a power supply, as it apparently did first
time.

I'm not saying you are odd that changing a PSU would bring about a cure the
first time.

Oops, that come out a bit wrong!!

I meant to say I am not saying that you are *wrong*, but it seems unlikely to
wreck a PSU.
