Chapter 3 Installing the Cisco ASR 901 Mobile Wireless Router

Connecting Cables

We provide the following cables and adapters for connecting the Cisco ASR 901 router to a console terminal:

One console adapter cable (RJ-45-to-DB-9, blue)

Types of RJ-45 Cables

Cisco products use the following three types of RJ-45 cables:

Straight-through

Crossover

Rolled (or Rollover)

The Cisco ASR 901 router ships with and uses the rollover cable. For instructions on how to identify a rollover cable, see Identifying a Rollover Cable, page B-5.

Console Port

Complete the following steps to connect a terminal or a PC running terminal emulation software to the console port on the router:

Step 1 Connect the terminal using an RJ-45 rollover cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter (labeled TERMINAL) to the console port. For cable pinouts, see the “Console Port Signals and Pinouts” section on page B-3.

Note The RJ-45-to-DB-25 adapter (Cisco part number 29-0810-01) can be purchased from Cisco Systems.

Step 2 Configure the terminal or terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.

Note Hardware flow control is not possible on the console port.
