Figure 3-27 Removing the AC Power Supply
Caution Do not use the captive installation screw or the power retainer to pull out the power supply.
Step 4 Grasp the AC power supply metal tab with one hand, and slide it part of the way out of the chassis. Place
your other hand underneath the power supply, and slide it completely out of the chassis. See Figure 3-24.
Step 5 Replace the AC power supply within 5 minutes. See Figure 3-24. If the power supply bay is to remain
empty, install a blank filler plate (Cisco part number 800-39165-01) over the opening, and secure it with
captive installation screws.
Installing and Removing SFP Modules
These sections describe how to install and remove SFP modules. The modules are inserted into the SFP
module slots as depicted in Figure 3-30. These field-replaceable modules provide interfaces.
See the Supported PIDs for the list of SFP modules that the router supports. Each port must match the
wavelength specifications on the other end of the cable. For reliable communications, the cable must not
exceed the stipulated cable length.
Use only Cisco SFP modules on the Cisco router. Each SFP module has an internal serial EEPROM that
is encoded with security information. This encoding provides a way for Cisco to identify and validate
that the SFP module meets the requirements for the router.
For detailed instructions on installing, removing, and cabling the SFP module, see the SFP module
documentation.
