The System Status display gives an overview of the entire system, both local and remote
units, the channel conditions, optical connections, and power supply status. In the above display
note that all Port cards are installed and that all 4 channels (1A~1B) are in service (v) without any
errors from local or remote side except for Port 4 which is a LAN card (The LAN card combines
the entire port throughput into a single WAN bridge). The optical 1 (O1) connection is working (W)
and optical 2 (O2) is in standby (S) mode. Both power supplies (P1 and P2) are active in both local
and remote side units.
The display screen will refresh every 5 seconds. If there is no link to the remote unit, then no
status information will be available from the remote side, all fields will go blank, and the refresh
will take more than 20 seconds.
Another important diagnostic display of the
Fiber Multiplexer
is the Alarm Buffer display.
Note that it is item three on the root menu. If we press "3" the Alarm Buffer will display.
