When you have completed installing the network interface cables on the left-most line card,
proceed to the next card in turn in the upper card cage. Repeat this procedure until you have
installed all of the network interface cables on all of the line cards present in the upper card
cage.
Connecting Route Processor Cables
The console and auxiliary ports for the Cisco 12008 are located on the RP. The GRP has an
optional Ethernet port and the PRP has two Ethernet ports. This section contains connection
equipment and pinout information for the console, auxiliary, and Ethernet ports on the GRP
and PRP.
GRP Console and Auxiliary Port Connection Equipment
The GRP has two EIA/TIA-232 ports: a DCE-mode console port and a DTE-mode
auxiliary port. The console port is a DCE DB-25 receptacle for connecting a console
terminal, which you need to configure the Cisco 12008. The auxiliary port is a DTE DB-25
plug for connecting a modem or other DCE device (such as a channel service unit/data
service unit (CSU/DSU) or other router) to the Cisco 12008 (see Figure 3-7).
