CAUTION:
This procedure requires a complete initialization of the system. All
software settable features will need to be reentered. If office records are
not available, all the settings listed
[DLP-511]
will need to be recorded,
so the settings can be reentered at the end of this procedure. The
cross-connections will most probably change. The new
cross-connections must be available from the provisioning center.
!
WARNING:
Unterminated optical connectors may emit invisible laser radiation. Avoid
direct exposure to the beam. Do not view beam with optical instruments.
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
!
CAUTION:
Before installing
28/29-Type
OLIU
s, ensure all optical fiber connectors
and couplings have been properly cleaned
[DLP-527]
. Signal
performance may be degraded if the connectors and couplings are not
cleaned properly.
!
CAUTION:
If optical fiber cables are routed beneath the
OLIU
s, be careful not to
pinch or crush the fibers when the
OLIU
s are inserted.
NOTE:
The DDM-2000 FiberReach shelf operating at an OC-3 rate requires
28-Type OLIUs in the MAIN slots. The DDM-2000 FiberReach shelf
operating at an OC-12 rate requires 29-Type OLIUs in the MAIN slots.
Two OLIUs are required.
NOTE:
The red FAULT LED flashes when no signal is present to the OLIUs.
NOTE:
The 28-Type and 29-Type OLIUs require a faceplate interconnect cable
assembly, [comcode (847721271)].
