Chapter 3 Installing the Router
Connecting GRP Route Processor Cables
Connecting to the GRP Auxiliary Port
The auxiliary port on the GRP is an EIA/TIA-232 DTE DB-25 plug for connecting
a modem or other DCE device (such as a channel service unit/data service unit
(CSU/DSU) or another router) to this router.

Use the following procedure to connect an asynchronous serial device to the
GRP auxiliary port.
GRP auxiliary port.
Step 1
Power off the asynchronous serial device.
Step 2
Attach the device end of the cable to the interface port on the asynchronous serial
device.
device.
Step 3
Attach the other end of the cable to the GRP auxiliary port.
Step 4
Power on the asynchronous serial device.
Connecting to the GRP Ethernet Port
The Ethernet port on the GRP supports two types of Ethernet ports as shown in
(
(
):
•
A media-independent interface (MII), 40-pin, D-type receptacle.
•
A media-dependent interface (MDI) RJ-45 receptacle.
The RJ-45 and MII receptacles on the GRP represent two physical connection
options for only one Ethernet interface; therefore, you can use either the
RJ-45 connection or the MII connection, but not both simultaneously.

Caution
The GRP can support only one Ethernet connection at a time. To prevent router
and network problems, do not connect both RJ-45 and MII cables to the Ethernet
receptacles at the same time, and use cables that comply with EIA/TIA-568
standards.
