Checking Enclosure Power Redundancy (Optional) - HPE 3PAR StoreServ 9000 Customer Self Install Manual

IMPORTANT: The Status LED at the storage system front is not illuminated green at this time.
Instead, after the power on sequence, the UID/Service LED is illuminated blue and the Fault LED
is illuminated amber. Later during the software Guided Setup, these LEDs turn off and the Status
LED becomes illuminated green.

Checking enclosure power redundancy (optional)

To verify that the storage system has been correctly configured to achieve power redundancy, complete
the following procedure:
CAUTION:
• Hewlett Packard Enterprise recommends checking for power redundancy before the system is
initialized. If the system is already initialized, checking the power redundancy could cause an
outage.
• To maintain power to the storage system during this procedure, only one power distribution unit
(PDU) should be powered off at a time.
NOTE: The generic term "power supply" refers to various types of power components, such as a power
supply unit (PSU), power cooling module (PCM), or a power cooling battery module (PCBM).
Prerequisites
Ensure that the power cabling for the storage system follows the guidelines for redundant power cabling.
See Guidelines for redundant power cabling on page 26.
