Connecting Route Processor Cables
Cisco 12008 Gigabit Switch Router Installation and Configuration Guide 3-22
Note
You must provide the EIA/TIA-232 cables to connect the terminal to the GRP
console port or other devices to the auxiliary port. Cisco Systems does not provide console
and auxiliary port cables; cables are available from other vendors. For compliance with GR-
1089 (intra-building surge), you must use shielded cables on the GRP console and auxiliary
ports.
Because the connectors on some standard cables are tall enough to interfere with the front
covers installed on the card cages, Cisco includes a lower-profile cable adapter that permits
you to connect a flat cable with modular RJ-45 plugs to the GRP console port.
For console and auxiliary port pinouts, refer to Table 3-1 and Table 3-2, respectively.
GRP Console Port Signals
Both Data Set ready (DSR) and Data Carrier Detect (DCD) signals are active when the
system is running. The console port does not support modem control or hardware flow
control. The console port requires a straight-through EIA/TIA-232 cable. Table 3-1 lists the
signals used on this port
Table 3-1 GRP Console Port Signals
