Replacing a power supply/fan assembly
This section describes how to remove and replace the power supply/fan
assemblies. Although these CRUs can be removed and replaced without special
tools, qualified personnel should perform the installation and service procedures.
The switch can continue operating during the CRU replacement if you adhere to
the conditions specified in the procedures.
Attention: Before installing, removing, or replacing any component, read and
follow the “Safety notices and labels” on page xiii.
The switch has two power supply/fan assemblies, #1 (
1
in Figure 11) and #2
(
2
). The power supply/fan assemblies are hot-swappable as long as one of them
remains operating during the procedure. Each power supply/fan is identical and
fits into either power supply/fan slot. Refer to “Power supply/fan status LED
patterns” on page 29 to help diagnose problems with a power supply/fan. You can
also use the
switchStatusShow command to verify the status of the power
supply/fan assemblies. Refer to the Fabric OS Command Reference for more
information on this command.
