Incorrect Cabling on Cisco ASR 1002 Router AC Power Supply
Note
Using a tie wrap for the AC power cable is optional and not necessary. However, if you do attach
the AC power cable to a power supply tab and then you remove the AC power cable for some
reason, check for any damage to the cable after you cut the tie wrap off. If the power cord is
damaged, replace it immediately.
Step 4
Plug the AC power supply cable into the AC power source.
This completes the procedure for connecting an AC power supply in the Cisco ASR 1002 Router.
Connecting –48 VDC Input Power to Cisco ASR 1002 Router
The –48 VDC power supply input connector is a Euro-style terminal block. A means to provide strain
relief to the input wires is provided on the power supply. The connection order is negative (
–
), positive
(
+
), and GND; but this is the order from left to right that the terminals appear on the power supply, not
the order in which the leads should connected during installation. The order the leads should be attached
is GND, positive (+), and negative (-).
The recommended branch circuit breaker for the Cisco ASR 1002 Router –48 VDC power supply is 30
A. Use a AWG #10 wire gauge on the 30 A circuit.
