Chapter 4. Removing and replacing CRUs
This chapter describes how to remove and replace the customer replaceable units
(CRUs) in the router. The CRUs for this router include the power supplies, fan
assemblies, the SFPs, and the entire router chassis (see “Parts list (CRUs)” on
page 60 for part numbers). Although these CRUs can be removed and replaced
without special tools, qualified service personnel should perform the installation and
service procedures. With the exception of the chassis replacement, the router can
continue operating during the CRU replacements 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 xv.
Refer to the following sections for specific CRU removal and replacement
procedures:

“Replacing a power supply”

v “Removing, and installing SFPs” on page 44
v “Replacing the router” on page 53
Replacing a power supply
Attention: Before installing, removing, or replacing any component, read and
follow the “Safety notices and labels” on page xv.
The router has two power supplies, power supply #1 (

in Figure 10 on page 40)
and #2 (

). The power supplies are hot-swappable as long as one power supply
remains operating during the procedure. Each power supply is identical and fits into
either power supply slot. Refer to “Power supply status LED patterns” on page 35 to
help diagnose problems with a power supply. You can also use the
switchStatusShow command to verify the status of the power supplies. Refer to
the Fabric OS Command Reference for more information on this command.
