3.2.2 LAN LEDs
Three LEDs indicate LAN activity. A red TxD LED comes on when if data is being
transmitted; A red RxD LED comes on if data is being received and a green Link LED comes
on if the connection is OK. If Ethernet is not connected, these LEDs will be off.
Note:
The RxD LED will flash for any data on the Ethernet, regardless of destination.
3.2.3 Port LEDs
There are two red Port LEDs, P1 and P2. Together with the Status LEDs, they indicate unit
status. When the unit is operating correctly, these LEDs ripple, with all status LEDs off.
When a problem exists, the Port LEDs will show its location (P1 or P2, or if both P1 and P2
are lit, a major alarm exists). The status LEDs will then indicate the problem (refer to
7.4.3
).
If more than one has a problem, they will be shown in a cycle of five seconds each.
3.2.4 Power LED
The Power LED has two functions. When power is applied, it comes on orange to indicate
the unit is in self-test mode. When the self-test has been satisfactorily completed, it changes
to green to indicate the unit is functioning correctly.
