Back Panel Equipment
P1 and P2
The two amber Port LEDs are labelled P1 and P2 . Together with the STATUS LEDs, they indicate unit
status. When the unit is operating normally and all is well, these LEDs turn on and off every few seconds
with all
STATUS LEDs off.
When a problem exists, the Port LEDs will show the problem’s location (P1 or P2, or if both P1 and P2
are lit, a major alarm exists). The
STATUS LEDs will then indicate the problem. If more than one port
has a problem, they will be shown in a cycle of 5 seconds each.
Power
The Power LED has two functions. When power is applied, it comes on amber to indicate that the unit is in
self-test mode. When the self-test satisfactorily completes, it changes to green to indicate that the unit is
functioning correctly.
