LED
Description
POWER
This green LED is on when the GRF power is on.
FAULT
This amber LED flashes once as the board starts self-test; then flashes once again
when self-test completes. If the Fault LED turns on and remains on, an error condition
has been detected.
STATUS
This green LED is on and flashes a “heartbeat” during positive board operation.
COM BUS ACTIVE
This green LED flashes during bus activity.
COM BUS TRANSMIT
This green LED flashes during bus activity.
COM BUS RECEIVE
This green LED flashes during bus activity.
PS1-OK
This green LED is on when power supply 1 is operating at required level. If the power
supply fails, the LED goes off.
PS2-OK
This green LED is on when power supply 2 is operating at required level. If the power
supply fails, the LED goes off.
LINK OK
This green LED is on while the Ethernet connection from the control board is good.
100
This green LED is on when the Ethernet is in 100Base-T mode. The LED is off under
10Base-T mode.
XMT ACT
This green LED flashes while data is sent to the management software.
RCV ACT
This green LED flashes while data is received from the management software.
During start-up, media card “PWR” LEDs come on green. This manual is organized so that
you attach cables after power on and can watch the progress of each card’s LEDs for indication
of normal or error conditions. Chapter 5 contains descriptions of all media card LEDs.
