Connecting to the Console Port and Auxiliary Ports
This section provides the information for connecting the console to the router.
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.
GRP Console and Auxiliary Ports
This section provides connection equipment and pin designation information for
the console and auxiliary ports on the GRP. There are several models of the GRP
that can be used with the Cisco 12404 router: GRP=, GRP-B=, and GRP-C=.
Note
To comply with Telcordia GR-1089 NEBS standard for electromagnetic
compatibility and safety, connect all console, auxiliary, and Ethernet interfaces
only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable
must be shielded and the shield must be grounded at both ends.
The GRP-C= does not require shielded cables for Class B, EMI compliance.
Note
To properly maintain Class B, EMI compliance, you must use shielded cables on
the console and auxiliary ports of the GRP= and GRP-B=.
The GRP has two EIA/TIA-232 ports:
•
DCE DB-25 receptacle for connecting a console terminal, and
•
DTE DB-25 plug for connecting other DTE devices
The DCE-mode auxiliary console port is a DCE- DB-25 and receptacle is used for
connecting a console terminal, which you will need to configure the Cisco 12404
router (
).
