PRP Auxiliary and Console Ports

The auxiliary and console ports on the PRP are EIA/TIA-232 (also known as

RS-232) asynchronous serial ports connect external devices to monitor and

manage the system.

• Auxiliary port—A (male) plug that provides a data terminal equipment

(DTE) interface. The auxiliary port supports flow control and is often used to

connect a modem, a channel service unit (CSU), or other optional equipment

for Telnet management.

• Console port—A (female) receptacle that provides a data circuit-terminating

equipment (DCE) interface for connecting a console terminal.

PRP Reset Switch

Access to the (soft) reset switch is through a small opening in the PRP front panel

(see

Figure 4-3). To press the switch, insert a paper clip or similar small pointed

object into the opening.

Caution The reset switch is not a mechanism for resetting the PRP and reloading the

Cisco

IOS XR image. It is intended for software development use only. To prevent

system problems or loss of data, use the reset switch only on the advice of Cisco

service personnel.
