IMPORTANT:
• Only one power cooling module can be serviced at a time. If another power cooling module is to
be serviced, verify that the first serviced power cooling module is healthy and functioning, and
then restart this servicing procedure from the beginning for the next power cooling module to be
serviced.
• To prevent overheating, the replacement of the power cooling module requires a maximum
service time of six minutes.
• Ensure that cables are clear of the power cooling module when installing.
IMPORTANT:
• The same HPE 3PAR -48VDC 764W Power Cooling Module is used in both the controller node
enclosures and the drive enclosures.
• The HPE 3PAR -48VDC 764W Power Cooling Module is shipped without a battery.
•
Before installation of the -48VDC 764W PCMs in the controller node enclosure
, batteries
are required to be installed in the -48VDC 764W PCM. Remove the batteries from the AC PCMs
and install the batteries in the -48VDC 764W PCMs.
IMPORTANT:
Because each battery is a backup for both controller nodes in the controller node
enclosure, controller nodes 0 and 1 both report a problem with a single battery. The
Qty
appears as
2
in output because two controller nodes are reporting the problem. Battery 0 for controller node 0 is
in the left PCM, and battery 0 for controller node 1 is in the right side PCM (when looking at the
controller node enclosure from the rear).
NOTE:
• The power switch on the HPE 3PAR -48VDC 764W Power Cooling Module is inverted 180° from the
orientation of the power switch on the alternating-current (AC) power cooling module.
• Labels on the HPE 3PAR -48VDC 764W Power Cooling Module show the model as -48VDC INPUT
764W PCM.
Prerequisites
• Arrange to have a certified electrician available during the installation to complete the power cabling
connections of the -48V direct-current (DC) power cooling module (PCM).
•
Only for the controller node enclosure
, verify that at least one PCM Battery in each controller node
enclosure is functional before removing a PCM.
