Identifying the spare part number
Parts have a nine-character spare part number on their label. If necessary, Hewlett Packard Enterprise
Support can assist in identifying the correct spare part number.

Figure 39: Sample product label on page 76 displays the spare part number shown in green.
Identifying swappable parts
Colored touch points on the part (such as a lever or latch) identify whether the system should be powered
on or off during a part replacement:
• Hot-swappable
Parts are identified by red-colored touch points. The system can remain powered on and active during
replacement.
• Warm-swappable
Parts are identified by gray-colored touch points. The system will not fail if the part is removed but data
loss may occur if the replacement procedure is not followed correctly.
• Cold-swappable
Parts are identified by blue touch points. The system must be powered off or otherwise suspended
before replacing the part.
IMPORTANT:
Hewlett Packard Enterprise does not support hot removal of storage controllers. Before removing a
suspect controller, fail over to the surviving controller, even if you are only reseating the controller.
If failover is not possible the use the unfolded paper clip to power off the controller.
