Figure 27: Removing the AC Power Supply
Do not use the captive installation screw or the power retainer to pull out the power supply.
Caution
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
Installing the AC
Power Supply
figure.
Step 5
Replace the AC power supply within 5 minutes. See
Installing the AC Power Supply
figure. 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
Installing an SFP Module without a Bale-Clasp Latch into an SFP Module Slot on Cisco
ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router
figure. These field-replaceable modules
provide interfaces.
See the
Supported PIDs
section 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.
