User Panel LEDs
6
The user panel LEDs show a composite of all alarms and status conditions in the
local shelf. The composite is defined as follows:
■
The highest level alarm LED (CR, MJ, PMN, or MN) of all alarms at the
local shelf is lit. (At most, one alarm LED will be lit at any time.)
■
The ABN LED is lit if an abnormal condition exists on this shelf.
■
The ACO LED is lit if the alarm cutoff function is active on this shelf.
■
Each PWR ON LED is lit if the local shelf is receiving
−
48 V power from its
power feeders.
■
The NE ACTY LED is lit if any alarm, ABN, or "activity" condition exists on
this shelf.
When this composite information is being displayed on the user panel, the
7-segment FE ID is blank.
FE SEL Pushbutton
6
In previous DDM-2000 FiberReach releases the FE SEL pushbutton allowed
technicians to see far-end DDM-2000 conditions from the local shelf. Starting with
FiberReach Release 3.0 and all later FiberReach TARP releases, when the FE
SEL pushbutton is pushed for the first time, the FE ID display shows "L" and the
user panel LEDs show the conditions of the local shelf only.
Each time the FE SEL pushbutton is pushed again within 15 seconds, the FE ID
display will show the local shelf address (with the decimal point), and the user
panel LEDs will show a composite of the alarm and status condition of that same
shelf.
