HP NonStop G-Series - Manual (Page 141)

Start
Starts the CRU's PIF. The PIF must be in the Stopped state before you perform this action. When the
Start action completes, the PIF is in the Started state.
Stop
Rather than automatically stopping the PIF (as the Abort action does), this action first warns you if
the PIF is currently in use (and stops it only after you confirm).
PMCU
The power monitor and control unit (PMCU) controls and monitors the battery connection to the DC
power distribution buses. Along with the service processor, the PMCU diagnoses the condition of the
batteries, fans, and power supplies and regulates the voltage supplied to the fans.
Location in OSM Tree: System > Group > Module > PMCU
Slot Location: PMCUs are located in slots 21 and 22 of processor enclosures (appearance side).
Example: PMCU (1.1.21)
