Put on the ESD gloves or wrist strap and connect the grounding terminal to the ESD jack
on the rack.
2.
Remove the connectors. Then, cover the connectors with dust caps.
NOTE
If a connector is dusty, clean it with a dust cloth or fiber cleaning tissue.
3.
Remove the old optical cable from the corrugated pipe.
Step 6
Insert the new optical cable.
Before inserting the new optical cable, remove the dust caps store them for future use. Then,
connect both ends of the new optical cable to the optical interfaces.
