these are much longer than on an Ultra 5.  the ones used in the big purple
UltraSPARC III cpu and also in the memory expansion connector in the E420R
(and i'm assuming the Ultra 80 since they have the same motherboard).  the
connectors have jack screws to extract and install the mating half of the
connector and i presume that there is a close limit of the torque required
to make a reliable connection and enough to destroy the connector so they
provide a torque wrench (of sorts) if you don't have the professional tool
to do it.
