HP ProLiant servers that support redundant power supplies only allow installation of same-type supplies. A power
supply mismatch or an unsupported power supply will result in an error indication as described in Table 4.

iLO will detect the mismatch and not allow the added power supply to turn
on.
Unsupported power
supply detected
during boot
Power supply LED
(added supply only)
blinking amber
BIOS ROM will detect an unsupported power supply installation. BIOS ROM
will halt at POST with a failure message and will light the appropriate LED.
The LED will reset when the unsupported supply has been removed and
system is restarted.
HP CS power supplies are hot-pluggable/hot-swappable on ProLiant servers under the following conditions:
• The server must already be configured with redundant power supplies.
• The removed and replacement power supplies must be of the same type (same part number).
For all other situations, the ProLiant server should be powered down before a power supply is removed or installed.
Conclusion
The common slot power supply bay allows over 90% of the ProLiant server line to use 80 PLUS-certified power supplies.
By using IT equipment that supports common-slot power supplies, IT and facilities administrators can reduce spares
inventory costs and space requirements while reducing energy consumption costs and reclaiming data center power
capacity.
