The console port functions as an asynchronous serial port; any devices connected to the console port must
be cabled for asynchronous transmission. (Asynchronous is the most common type of serial device; for
example, most modems are asynchronous devices.)
Note
Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement

Warning
The Cisco ASR 901S Series Aggregation Services Router uses a RJ-45 port for the console port.
Complete the following steps to connect a terminal or a PC running terminal emulation software to the console
port on the router:
Procedure
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
Connecting Console Port and Pinouts , on page 92
.
The RJ-45-to-DB-25 adapter (part number: 29-0810-01) can be purchased from Cisco Systems,
Inc.
Note
Step 2
Configure the terminal or terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.
Hardware flow control is not possible on the console
port.
Note
Connecting Network Cables
This section describes how to connect the following router interfaces:
Connecting Gigabit Ethernet Interface Cables
The RJ-45 port supports standard straight-through and crossover Category 5 (Cat5), shielded twisted pair
(STP) cable.
The Cisco ASR 901S Aggregation Services Router is not shipped with Category 5 STP cables; these
cables are available commercially and need to be procured.
There are two ways to install the RJ45 copper cable:
Note
•
Externally
—
Through the copper port (Cu).
•
Internally
—
Through the cable gland. For information about installing the cable through the cable
gland, see
Installing Cable Glands, on page 59
