LINK—Indicates link activity.

ACT—Indicates which Ethernet port is selected (ETH 0 or ETH 1). 

Because both ports are supported on the RSP/RP card, MGT LAN 0 is always on. MGT LAN 0 
lights when it is selected.

The auxiliary and console ports on the RSP/RP are EIA/TIA-232 (also known as RS-232) asynchronous 
serial ports connect external devices to monitor and manage the system:

Auxiliary port—RJ-45 interface that 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—Receptacle (female) that provides a RJ-45 interface for connecting a console 
terminal. 

The alphanumeric message displays are organized in one row of four LED characters (see callout 8 in 

 for the RSP card, callout 12 in 

 for the RSP-440 and RSP-440 Lite cards, callout 

13 in 

 for the RSP-880 card, callout 13 in 

 for the RP card, and callout 13 in 

 for the RP2 card. 

The alphanumeric message displays show router status messages during the boot process and after the 
boot process is complete:

During the boot process, the message displays are controlled directly by the CAN microcontroller.

After the boot process, the message displays are controlled by Cisco IOS XR software (through the 
CAN bus).

The alphanumeric message displays also provide information about different levels of system operation, 
including the status of the RSP/RP, router error messages, and user-defined status and error messages.
