OK LED – Module Health
A bicolor OK LED indicates module health. A red LED indicates that
module startup diagnostics have failed or a major module fault such as
watchdog timeout or jabber inhibit has occurred. Green indicates that the
card has passed all power-up diagnostics and is functioning normally.
This LED is red during powerup.
All LEDs Red
If all three LEDs are solid red and the 4-character display shows
