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

object into the opening.
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.
