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. These ports connect external devices to
monitor and manage the system.
• The 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.
• The console port—A (female) receptacle that provides a data
circuit-terminating equipment (DCE) interface for connecting a console
terminal.
PRP-3 LEDs
The PRP-3 has the following LED indicators:
• Two Ethernet port LEDs used in conjunction with each of the three RJ-45
Ethernet connectors:
– LINK—Indicates link activity
– DATA—Indicates data transmission or reception
• Two BITS port LEDs used in conjunction with each of the two BITS ports:
– SIG—Indicates carrier signal available
– ACT—Indicates that the interface is active
Note BITS feature is not supported in Release 3.8.0.
• One auxiliary port (AUX) and one console port (CONSOLE) LED:
– AUX—Used as a backup for the command outputs on the Console.
– CONSOLE—Used for configuring the router by connecting an RJ-45
cable to the console terminal. The router can be configured through the
console terminal.
