Chapter 3 Installing the Router
Connecting the Network Cables
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 an RJ-45 rollover cable with an RJ-45-to-DB-25 adapter.
The provided adapter is labeled MODEM. For cable pinouts, see the online publication
Cisco Modular
Access Router Cable Specifications
available both on the Documentation CD-ROM and CCO.
Step 2
Make sure that your modem and the router auxiliary port are configured for the same transmission speed
(up to 115200 bps is supported) and hardware flow control with Data Carrier Detect (DCD) and Data
Terminal Ready (DTR) operations.
Connecting the Network Cables
This section describes connecting the following support MWR 1941-DC router interfaces:
•
Connecting the Fixed FE Interface Cables, page 3-5
•
Connecting the VWIC Interface Cables, page 3-6
•
Connecting the WIC-2A/S Interface Cables, page 3-8
•
Connecting the Network Module Interface Cables, page 3-9
Connecting the Fixed FE Interface Cables
The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair
(UTP) cables (refer to Figure 3-15). Cisco Systems does not supply Category 5 UTP cables; these cables
are available commercially.
Step 1
Confirm that the router is turned off.
Step 2
Connect one end of the cable to the FE port on the router.
Step 3
Connect the other end to the BTS patch or demarcation panel at your site.
