Installing a Cisco 12008 3-43
Connecting Source Power to the Power Supplies
To connect source power to an AC-input power supply, perform the following steps:
Step1 Verify that the rotary power switch on the power supply is in the Standby (OFF)
position.
Note A power supply bay not occupied by a power supply must have a power
supply blank installed for EMI compliance and to ensure proper airflow through
the router.
Step2 Locate the AC power cord shipped with your system and verify that it is the
correct type for your particular site.
For this purpose, refer to the section in Chapter 2 entitled “AC-Powered
Systems.”
Note If the proper power cord was not shipped with your system, contact your
service representative.
Step3 First ensure that the bail latch is pushed down; then plug the AC power cord into
the AC receptacle on the power supply faceplate (see Figure3-19).
Note If you have a redundant AC-input power supply configuration, we
recommend that you connect each power supply to an independent AC power
source and install an uninterruptable power source (UPS) in your site to protect
your router against power failure. Each AC-input power supply operating
between 200 VAC and 240 VAC requires a dedicated 20A service.
Step4 Position the bail latch over the power cord plug by pulling the latch up and over
the plug to secure the plug in the AC receptacle on the power supply faceplate
(see Figure3-19).
