Safety rules
Description
The safety rules describe the operations and/or precautions to observe to safeguard
operating personnel during the working phases and to guarantee equipment safety. Please
read the
1850 TSS-320 Safety Guide before starting each task.
General rules
Check that the equipment is operating with all the shields properly positioned (dummy
covers, ESD connector protections, etc.).
Carefully observe the front-panel warning labels prior to working on optical connections
while the equipment is in-service.
To reduce the risk of damaging the electrostatic sensitive devices, it is mandatory to use
the elasticized band (worn around the wrist) and the coiled cord connected to the rack
ground when having to touch the equipment.
All measures must be done at the ODF/DDF points (ODF= Optical Distribution Frame,
DDF= Digital Distribution Frame).
Inserting the units (and modules) into the subrack
The screw tightening torque for inserting the units (and modules, if any and if screw
fastened) into the subrack must be:
2.8 kg x cm (0.28 Newton x m) ± 10 %
Exceeding this value may result in screw breaking.
CAUTION
Carefully read the front-panel warning labels prior to working on any
connections.
CAUTION
Avoid equipment damage
