Prosody X PCI Express R1 Card – Installation Guide
2.3.2 Ethernet interface LEDs
A set of LEDs is used to indicate the status for each Ethernet interface. Once a
connection has been made to a network, the interface LEDs will show activity, frame
clocking etc. Only one of the connections should show activity due to transmit and or
receive call traffic (numbered from right to left):
1 = Link Activity
2 = 100Mbps
3 = Link Up
2.3.3 Host Ethernet interface LEDs
The host Ethernet interface LEDs indicate the following (numbered from right to left):
1 = N/A
2 = Link Activity
3 = 100Mbps
2.3.4 Firmware controlled LEDs
Card firmware LED status
In normal operation the six LEDs D6-D11 are flashing in a “walking one” sequence.
Trunk firmware LEDs
Once initialised, LEDs D18-21 indicate E1/T1 trunk activity as follows :
D18 trunk 3
D19 trunk 2
D20 trunk 1
D21 trunk 0
Inactive trunks will have the corresponding LED turned off. After trunk initialisation
(firmware download) the LED will turn on.
With the exception of SS7 protocols, where the default behaviour is layer 1 state
monitor, during normal operation the firmware LEDs will be seen to flash to indicate
call activity.
Layer 1 state monitor
This is the default for SS7 protocols. Most other protocol firmwares can be changed
to monitor layer 1 by the use of a firmware switch; check the appropriate protocol
release notes for details of the available protocol switches.
When monitoring layer 1, the state of a trunk will be indicated by its associated LED
(LED on indicates a good layer 1. LED off indicates a bad layer 1).
