GRP Auxiliary and Console Port Connections
The GRP has two EIA/TIA-232 ports (Figure 2-12):
• Auxiliary port— DB-25 plug, DTE-mode port for connecting a modem or
other DCE device (such as a CSU/DSU or another router) to the GRP.
• Console port—DB-25 receptacle, DCE-mode port for connecting a data
terminal to perform the initial configuration of the router.
Note The auxiliary and console ports are asynchronous serial ports. Devices
connected to these ports must be capable of asynchronous transmission.
Figure 2-12 GRP Auxiliary and Console Port Connections
Because the connectors on some standard cables are large enough to interfere with
the front covers installed on the card cages, a lower-profile cable adapter is
included that permits you to connect a flat cable with modular RJ-45 plugs to the
GRP console port.
Note EIA/TIA-232 cables are not available from Cisco, but are available from any
commercial cable vendor.
