Connecting to the GRP Ethernet Port
Caution
OL-11495-01
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.
See the
"GRP Auxiliary and Console Port Connections" section on page 2-26
more information.
Use the following procedure to connect an asynchronous serial device to the
GRP auxiliary port.
Power off the asynchronous serial device.
Attach the device end of the cable to the interface port on the asynchronous serial
device.
Attach the other end of the cable to the GRP auxiliary port.
Power on the asynchronous serial device.
The Ethernet port on the GRP supports two types of Ethernet ports as shown in
(Figure
3-19):
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.
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.
