Cisco ASR 1006 Router DB-25 Pinout Assignments for Alarm Relays
The alarm ports for the Cisco ASR 1006 Router (and Cisco ASR 1004 Router) power supplies reside on
the DB-25 connector on the face of the power supply. The alarm ports are relay contact closures that the
IOS environmental software controls. The environmental monitoring functions of the system can include
voltage and temperature monitoring for the router installed components and failure sensing for power
supply fan tray.
Any alarms that light the front panel LEDs on the Cisco ASR1000-RP1 causes a contact closure between
the corresponding pins within the DB-25 alarm port of both power supplies. In the DB-25 connector,
each alarm consists of a three-pin set containing a common pin, a normally open pin, and a normally
closed pin. The connections that describe alarm activity are Alarm off (Common is connected to
normally closed and normally open is disconnected) and Alarm on (Common is connected to normally
open and normally closed is disconnected).
Table A-7 lists the common, normally open, and normally closed relay contacts accessible to an external
alarm monitoring facility by means of the DB-25 connector.
