Replacing a direct-current power cooling module in a drive enclosure—SP
5.x
This procedure is for the replacement of an -48V direct-current (DC) power cooling module (PCM) in a
drive enclosure using HPE 3PAR Service Processor (SP) 5.x.
WARNING: Since there is a risk of injury from electric shock or high energy levels, only a certified
electrician who knows about the procedures, precautions, and hazards associated with direct-
current (DC) power should perform the power wiring, cabling, routine maintenance, and service of a
storage system installed in a direct-current power environment. Hewlett Packard Enterprise and
partner service personnel are not authorized to perform DC power wiring or cabling.
CAUTION: Connecting to a direct-current power source outside the designated -48V DC nominal
range (-36V DC to -72V DC) may damage the direct-current power cooling module.
IMPORTANT: The direct-current components are qualified and supported only with a direct-current
HPE 3PAR StoreServ 8000 Storage system running HPE 3PAR OS 3.3.1 and later versions.
IMPORTANT: The storage system ordered for installation in a direct-current (DC) power
environment requires the installation of DC-specific components. Use of components with
alternating-current (AC) power in the DC storage system is prohibited.
