Stand-Alone (Local) Installation Tests for the DDM-2000 OC-12 Multiplexer
Lucent Technologies - Proprietary
See Notice on first page
!
WARNING:
Invisible laser radiation when open. Avoid direct exposure to beam. Observe all
precautions when handling fiber.
NOTE:
Prior to beginning the installation tests, disconnect the office alarms from the
shelf to prevent alarming during tests.
NOTE:
To add a circuit pack to the SYSCTL’s equipment list, the circuit pack needs only
to be installed. However, to delete a circuit pack from the SYSCTL’s equipment
list, an UPD/INIT must be performed after the pack is unseated; otherwise, the
system will alarm.
NOTE:
It is important that circuit packs be installed or replaced only when the SYSCTL
is in place and operating normally. Replacing or installing circuit packs when the
SYSCTL is not in place and operating normally can result in unpredictable provi-
sioning of the replaced/installed circuit pack.
LED, Push-button, and Display Descriptions
The LEDs have a delay default of 2 seconds. Therefore, the LEDs will not light until the
problem has existed for 2 seconds. This delay can be altered with the
set-attr
command.
The user panel contains the EIA-232D connector and the LEDs required to perform the
installation tests and is shown in Figure 6-1 on page 6-33.
The following LEDs are located on the circuit packs:
