Connecting Power To The Router; Connecting Power To An Ac-Powered Router - Cisco ASR 9000 Series Installation Manual

Connecting Power to the Router

The alarm subconnector can be used to connect the router to an external site alarm maintenance system.
Any critical, major, and minor alarms generated by the router also energize alarm relays on the alarm
card and activate the external site alarm. The alarm relay contacts on the RSP/RP card consist of standard
common, normally open, and normally closed relay contacts that are wired to the Alarm Out connector
pins.
Table 1-8
Because alarm contact cables are entirely dependent on installation site circumstances, alarm connector
cables are not available from Cisco. For information about alarm connector wiring requirements and the
pinouts for the alarm connector interface, see the
Only safety extra-low voltage (SELV) circuits can be connected to the Alarm Out connector. Maximum
Caution
rating for the alarm circuit is 100 mA, 50 V.
To comply with the intra-building lightning surge requirements of GR-1089-CORE, Issue II,
Note
Revision 01, February 1999, you must use a shielded cable when connecting to the external alarm port
on the RSP/RP card. The shielded cable is terminated by shielded connectors on both ends, with the
cable shield material tied to both connectors.

Connecting Power to the Router

Caution A router must be operated with all its power modules installed at all times for electromagnetic
compatibility (EMC).

Connecting Power to an AC-Powered Router

Follow these steps to connect the AC power cords to the router.
Note
Check that the power switch is set to the OFF (0) position. On version 1 power trays, this switch is at the
Step 1
rear of the power tray. On version 2 power trays, this switch is at the front of the power tray.
Check that the circuit breaker assigned to the AC power source you are connecting is set to OFF.
Step 2
Connect the permanent ground connection (central office grounding system) to the NEBS grounding
Step 3
location on the router chassis.

Connect each AC power supply to a dedicated power source (branch circuit). Each AC input
power supply operates at a nominal input level of 200 to 240 VAC. For more information on AC
power input levels, see the
