Note - The CMU replacement kit includes plastic covers to protect CMU connectors. Do not discard the covers. The covers are to be returned to Oracle.
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.
A new CMU does not have DIMMs. The DIMMs from the old CMU will be transferred to the new CMU in this procedure.
Caution - A CMU is heavy. Without DIMMs, a CMU weighs 44.4 lbs (20.1 kg). A fully-loaded CMU weighs 56 lbs (25.5 kg).
Note - Do not rely on checking the events list. The DIMMs on the CMU will not appear in the list unless they were moved to different slot numbers.
Use the DIMM or DCU information that you determined in Remove a CMU .
