How did you attempt to clean the compression connectors?

If you vacuumed across the compression connectors in a dry room, there
is a very good chance that you killed them.  SGI recommended to me using
a horsehair brush or computer-grade compressed air in a reasonably humid
environment as the ONLY way of cleaning a compression connector, and
that's only if it -needs[0]- to be done.

Which model IP30 do you have?

Unfortunately, it sounds that way.

[0] They never need to be cleaned unless they were out of the case in a
    dirty environment with the connector covers removed.  It's
    impossible for them to get dirty while mated to the frontplane.
