Cisco 7000 Hardware Installation And Maintenance

1-20 Cisco 7000 Hardware Installation and Maintenance
Physical Description
The RP, SSP (or SP), and interface processors (collectively referred to as processor modules) slide
into slots in the rear of the router and connect directly to the backplane; there are no internal cables
to connect. Spring-loaded ejector levers help to ensure that a processor module is either fully
connected to the backplane or fully disconnected from it. Captive installation screws at the top and
bottom of each processor module faceplate also ensure proper seating in the backplane, and prevent
the processor module from disengaging from the backplane. (The system will hang if a processor
module pulls away from the backplane and breaks the connection between the processor module
connector and the backplane pins.) Empty slots contain a blank board carrier (an interface processor
carrier without a board, LEDs, or connectors) to maintain proper airflow through the chassis.
One 700-watt (W) power supply is standard equipment in the router. A second, identical power
supply provides a redundant power option. Load sharing and redundancy are automatically enabled
when a second power supply is installed; no configuration is required. Each supply has an individual
power switch and status LEDs. When only one power supply is used, it should be installed in the
bottom power supply bay to maintain a low center of gravity in the router chassis.
