Chapter 9 Installing Line Cards 75
Note – Do not look at the individual holes, rather look at all of the connector’s holes
as a group. A damaged or contaminated hole will be apparent.
4. Look for any closed over or contaminated holes.
A closed-over or contaminated hole appears brighter than the surrounding holes.
If you see any closed-over or contaminated holes, use the magnifying glass and
pick to remove the contamination or open the closed-over hole.
Verify that the contamination has been removed from the connector and the
connector surface is clean. Use a spare midplane connector pin to verify the
resistance to insertion.
■
If there is great resistance, but the pin does enter the hole properly, investigate
why.
■
If the pin does not enter the hole at all, reject the line card. Contact your
SunService
SM
representative.
5. Look for any enlarged or cracked holes.
An enlarged or cracked hole appears darker than the surrounding holes.
If you see any enlarged or cracked holes, use a spare midplane connector pin to
verify the resistance to insertion.
■
If the insertion gives a little resistance and the pin does not wobble in the hole,
the connector is still acceptable.
■
If there is no resistance to insertion and the pin can wobble in the hole, reject
the fabric card. Contact your SunService representative.
6. Move your head slightly right to the next connector, and inspect its pins,
repeating Step 4 and Step 5 .
7. Continue in this manner for each connector until you reach the right side of the
line card.

To Inspect the iPASS Connectors
The small iPASS connectors on the line card are for the InfiniBand cables. The design
of these connectors is much simpler and more robust, so inspection is much easier.
●
Check the small connectors for any debris, or cracked or bent fittings.
Most debris can be blown out. If you find a cracked or bent connector, contact
your Sun Service representative.
