Release 8 Installation Tests
Prior to beginning the following tests the office alarm interface to this shelf (either
J56 or J57) should be removed before tests are executed and replaced upon
completion.
The following tests should be performed with the DDM-2000 OC-3 configured with
the default parameters described under "Login Procedure", as described later in
this section.
Observe the following notes:
!
WARNING:
Unterminated optical connectors may emit laser radiation. Do not view
beam with optical instruments. Avoid direct exposure to beam.
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 must be performed after the pack is unseated to
clear alarms. If cross-connects exist they must be removed to clear a circuit
pack. If in-service ports exist they must be set to auto to clear an in-service
port.
NOTE
:
It is important that circuit packs not be installed or replaced when the
SYSCTL is not in place and operating normally. Replacing or installing cir-
cuit packs when the SYSCTL is not in-place and operating normally can
result in unpredictable provisioning of the replaced/installed circuit pack.
LED, Pushbutton, and Display Descriptions
The LEDs have a delay default of 2 seconds. Therefore, the LEDs will not light
until an alarm condition has existed for 2 seconds. This delay can be altered with
the
set-attr
command.
The following LEDs are located on the circuit packs:
* A flashing FAULT LED on the OHCTL indicates a loss of communication with the
far-end SYSCTL
** DS1 packs do not have an ACTIVE LED but are assumed to be in-service
unless other information is provided through the CIT.
LED Description
FAULT(solid) Circuit pack is failed
FAULT (flashing) Circuit pack has lost its input signal*
ACTIVE Pack is carrying service**
