HPE recommends using the Maintenance Window functionality within the HPE InfoSight portal to inform HPE Support of
upcoming maintenance windows.
Refer to https://infosight.hpe.com/dashboards/nimble/wellness/maintenance-windows for more information.
You can disable automated support case generation during planned maintenance from the Manage Maintenance Windows
page. After a maintenance window is set, no further communication with HPE Support is required.
A PSU with an amber LED may have a fault. But an amber LED also indicates:
• The external power is switched off with the DC power connected
• The power supply is not properly seated in its slot
• The array is powered off
• A power supply internal fault has occurred
Verify that the power cord is plugged in, then check for and correct these conditions before you assume that the PSU in your
HPE storage array needs to be replaced.
CAUTION:
Before you attempt to replace a power supply:
• Do not remove the PSU until you are ready to install the
replacement
• Never unplug or unseat both PSUs at the same time
• Use only UL-approved power cords
Procedure
1. Identify the failed PSU.
The LED on a failed PSU is amber or dark.
2. Remove the power connections.
CAUTION: Before proceeding, verify that the DC power source is turned off at the circuit breaker.
a) Push the power supply release lever to the left, grasp the handle, and pull the power supply out several inches to access
the connector cover.
