System Status LEDs

The sections describes the two types of system status LEDs used on the PRP: LED
indicators and alphanumeric LED displays.
The device or port activity indicators consist of the following functional groups:
•
Two Flash disk activity LEDs (labeled SLOT-0 and SLOT-1)—1 LED per Flash disk
slot: these go on when the slot is accessed.
•
Four RJ-45 Ethernet port LEDs (labeled LINK, EN, TX, and RX): used in conjunction
with each of the RJ-45 Ethernet connectors. Each connector includes a set of 4 LEDs
that indicate link activity (LINK), port enabled (EN), data transmission (TX), and data
reception (RX).
•
Two Ethernet connection LEDs (labeled PRIMARY): these two LEDs, when on,
identify which of the two Ethernet connections is selected. Since both ports are
supported on the PRP, the LED on port ETH0 is always on. The ETH1 LED goes on
when it is selected.
The alphanumeric display LEDs are organized as two rows of four characters each and are
located at one end of the card. These LEDs provide system status and error messages that
are displayed during and after the boot process. The boot process and the content displayed
are controlled by the PRPs MBus module software.
At the end of the boot process, the LEDs are controlled by the Cisco IOS software (via the
MBus), and the content displayed is designated by the Cisco IOS software.
The alphanumeric display LEDs provide information about the following:
•
Status of the PRP
