Chapter 2 Preparing to Install the Router

Console Port Considerations

Creating a Site Log

The site log provides a record of all actions related to installing and maintaining the router. Keep it in

an accessible place near the chassis so that anyone who performs tasks has access to it.

Create the site log prior to installation. (See Appendix C, “Site Log” for more detailed information on

the site log as well as a sample site log that can be used to make copies.)

Console Port Considerations

The Cisco ASR 901 router provides a single console port (labeled CONSOLE). A single RJ-45 cable is

used for a console connection.

This section describes important cabling information to consider before connecting a console

terminal—either an ASCII terminal or a PC running terminal emulation software—or a modem to the

console port. The console port provides access to the router either locally (using a console terminal), or

remotely (using a modem).

Note The Cisco ASR 901 router uses only console port.

Note Console and rollover cables are not included with the Cisco ASR 901 router. You can order the console

cable from Cisco Systems, Inc. (Part number ACS-1900ASYN=).

Console Port Connections

The router provides an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable

and the adapter used, this port appears as a data terminal equipment (DTE) or data communications

equipment (DCE) device at the end of the cable.
