This section contains the removal procedures for the FRUs listed in the preceding table. Each of these procedures
indicates any power removal requirements for the FRU. If a customer replaceable unit (CRU) needs to be removed
during the procedure, it is designated as a CRU. If necessary, refer to Chapter 3 in the HP-UX Operating System:
Continuum Series 400 Operation and Maintenance Guide Release 1.0 (R025H-01-ST) for its removable procedure.
