Meaning
Normal state
Normal state
Normal state. The switch fabric board is
powered up.
Normal state
Normal state. The port board is powered up.
Normal state
No ATM cells are being received. This is not a
normal state if the terminating port network is
supposed to be up and running.
ATM cells are being received intermittently.
This is a typical pattern for Avaya Definity
Server CSI if only Variable Bit Rate (VBR)
signaling connections are present but no talk
paths are up, perhaps because no calls are in
progress.
ATM cells are being received frequently
enough that the LED is lit constantly. This is a
typical pattern for Avaya Definity Server CSI if
Constant Bit Rate (CBR) talk paths are
present.
Loss of carrier on the fiber. The A500 detects
only if the A500-receive (right-hand) fiber is
not working. The state of the A500-transmit
(left hand) fiber is not detected.
Normal state. There is a optical carrier
detected on the fiber from the TN230X.
Normal state
Normal state. AC power is okay.
Normal state. DC power is okay.
