CMUs are hot-pluggable components. See CMU Cage Component Locations for the location of CMUs.
Caution - The CMU is very susceptible to ESD damage. Use an antistatic wrist strap when working with the CMU. Use a grounded antistatic mat, particularly when opening a packaged CMU.
Caution - The CMU is heavy. A fully-loaded CMU weighs 56 lbs (25.5 kg).
Caution - Do not remove more than one CMU at a time. Fill the empty slot as soon as possible to avoid overheating the server.
Note - Before installing SPARC M6 CMUs into a SPARC M5-32 server, see CMU Configuration.
