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:
DDM-2000 circuit packs contain static sensitive components
which can be damaged by electrostatic discharge. A static
ground wrist strap must be worn when handling the circuit
packs. See electrostatic discharge considerations in
Trouble Clearing: TAD-100
.
NOTE:
If the DDM-2000 fails to respond in the indicated manner,
refer to Trouble Clearing: IXL-001.
NOTE:
It is assumed that the DDM-2000 FiberReach shelf in the
system has passed the looped transmission test(s) (System
Turnup: NTP-007). It is also assumed the DDM-2000 OC-3
shelves have been equipped and tested (363-206-285,
DDM-2000 OC-3 Multiplexer, TARP Release 13 and Later,
User/Service Manual (TOP) — Volume II
