Installing the Router 3-21
Connecting the Console Terminal and Modem
Connecting a Modem to the Auxiliary Port
Take the following steps to connect a modem to the auxiliary port on the router:
Step 1 Connect a modem to the auxiliary port using the thin, flat, RJ-45-to-RJ-45
roll-over cable (looks like a telephone cable) with the RJ-45-to-DB-25 adapter
(labeled “MODEM”) included with the router. (See Figure 3-17.)
Step 2 Make sure that your modem and the auxiliary port on the router are configured for
the same transmission speed (38400 baud is typical) and hardware flow control
with Data Carrier Detect (DCD) and Data Terminal Ready (DTR) operations.
Warning This equipment is intended to be grounded. Ensure that the host is connected to
earth ground during normal use. (To see translated versions of this warning, refer to the
Regulatory Compliance and Safety Information document that accompanied the router.)
