Cisco ASR 1004 Hardware Installation Guide

*For information about the
DB-25 alarm connector, how
it works, and Cisco ASR
1000 series route processor
LEDs, see the xref section.
Note: Shielded cables must
be used to connect to the
DB-25 alarm connector on
both the AC and DC power
supplies, in order to comply
with
FCC/EN55022/CISPR22
Class A emissions
requirements.
Step 4
Unplug the power cable from the AC inlet on the back of the power supply and the power source.
Step 5
Unscrew the power supply captive screws.
The Cisco ASR 1013 router has two power zones, each containing two power supplies for a redundant system.
Power supplies must be installed in the chassis at all times to ensure sufficient cooling. The system fans are
inside the power supply units and must spin for cooling. Because all the system fans can be powered by one
power supply, the second power supply unit does not have to be powered on, but it must be installed.
Note
If you remove a power supply, the system can run for a maximum of five minutes before the system shuts
down. The fans and power elements are independent within the power supply. Therefore, it is not required
that the replacement power supply be energized within five minutes. The only requirement is that the power
supply be installed in the chassis, which energizes the fans and maintains proper system cooling.
Caution
Step 6
Grasping the power supply handles, pull the power supply from the chassis.
Step 7
Replace the AC power supply within five minutes.
What to Do Next
This completes the procedure for removing the AC power supply from the Cisco ASR 1013 chassis.
