Power Subsystems

Power Source Monitoring

The alarm card monitors the power modules and signals when there is a condition outside the normal range of operation. It discloses problems such as the following:

•Power source voltage is not being provided to a component

•A fault exists in the power source or power module

•Output voltage—Voltage monitor signal is outside the allowable range

•Output current—Current monitor signal is outside the allowable range

Alarm Relay Contact Connector

The 9-pin D-type alarm relay contact connector on the faceplate of the alarm card (see Figure 1-11) is used to connect external alarm indication equipment to the router so that alarm indicator signals in the router can be repeated elsewhere outside the router.

The pins on this connector are tied directly to the critical, major, and minor alarm relay contacts (normally open, normally closed, and common). Any event that causes one of the alarm LEDs on the alarm card faceplate to go on also activates the corresponding relay contact closure. The relay interface is rated at a maximum of 2A, 60V, or 50VA, whichever is greater.

Because alarm contact cables are entirely dependent on site-specific circumstances, alarm connector cables are not available from Cisco. For information about alarm connector wiring requirements and the pinout for the alarm connector interface, see the “Alarm Card Alarm Relay Connector Specifications” section on page A-6.

Power Subsystems

Cisco 12006 and Cisco 12406 routers can be powered by either an AC or DC power subsystem, as described in the following sections:

•AC Power Subsystem, page 1-38
