Console and Auxiliary Port Connection Equipment

The RP (and RSP7000) contain two EIA/TIA-232 ports: a DCE-mode console port (DB-25
receptacle) and a DTE-mode auxiliary port (DB-25 plug). These are asynchronous ports (unlike the
synchronous FSIP serial ports), so be sure that any devices you connect to these ports are
asynchronous. Synchronous transmission uses precise timing to synchronize transmissions between
the transmitter and receiver, and maintains separate clock and data signals. Asynchronous
transmission uses control bits to indicate the beginning and end of characters instead of a precise
clock signal.
You need a console terminal to configure the interfaces and bring the system online. You also need
an EIA/TIA-232 DCE console cable to connect the terminal to the console port on the RP (or
RSP7000). After you establish normal operation, you can disconnect the terminal. Both ends of the
console cable should be EIA/TIA-232 plugs to enable you to connect to the RP (or RSP7000) DCE
console port DB-25 receptacle and to the DB-25 receptacles used on the DTE ports on most
terminals.
Before you connect a terminal to the console port, configure the terminal to match the router console
port as follows: 9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2).
The auxiliary port is a DTE DB-25 plug that you can use to connect an asynchronous modem,
another router, a CSU/DSU, or other DCE equipment. You also must supply your own interface
cable between the auxiliary port and the equipment you are connecting. For console and auxiliary
port pinouts, refer to the appendix "Cabling Specifications."
Tools for Installation
Following are the tools and equipment you will need to install the chassis and the optional
rack-mount kit:
•

2-110 Cisco 7000 Hardware Installation and Maintenance
Number 1 and number 2 Phillips screwdrivers to tighten the captive installation screws on most
systems.
1/4-inch flat-blade screwdriver for the captive installation screw on some power supplies and for
the chassis feet (you can also use a 7/16 open-end wrench for the chassis foot).
3/16-inch flat-blade screwdriver for the captive installation screws on the RP, SSP (or SP), and
interface processors in some systems.
Antistatic mat or antistatic foam in case you need to remove interface processors to troubleshoot
the installation.
Your own ESD grounding strap or the disposable ESD strap included with the system.
If you are installing the chassis in a rack, you will also need the following:
— Rack-mount kit (the kit is shipped with the chassis in the same shipping container)
— Phillips screwdrivers: number 1 and number 2
— Flat-blade screwdrivers: 3/16-inch and 1/4-inch
— 10-mm nut driver
— 7/16-inch open-end wrench or an adjustable wrench
— Tape measure and level (if needed)
