Antigravity Clutches
There are antigravity clutches on the system for CPU/Memory boards, IB_SSC
assemblies, and L2 Repeater boards. This chapter explains how to replace clutches
for these boards and assemblies. This chapter describes how to remove and replace a
clutch.
Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an ESD-protected mat. Store ESD-sensitive
components in its ESD safe packaging box before placing them on any surface.
Caution – This procedure requires the system to be extended out of the system
cabinet on its slides. You must extend the system cabinet stabilization bar.
14.1 Clutch
The replacement antigravity clutch kit contains three different types of clutches, one
for each type of FRU. They can be identified by their part numbers, which are listed
in the
Sun System Handbook .
