Connecting Optical Fiber - H3C S3100 Series Installation Manual

Keep the removed filler panel properly for future use.
Step 3: Unwrap the interface module. Gently push the interface module in along the slot guide rails until
the interface module is in close contact with the switch.
Step 4: Tighten the captive screws with a Phillips screwdriver to fix the interface module.
Removal procedure
Step 1: Wear an ESD-preventive wrist strap, ensure a good skin contact and make sure that the
ESD-preventive wrist strap is properly grounded.
Step 2: Use a Phillips screwdriver to loosen the captive screws at both sides of the interface module
until all spring pressure is released.
Step 3: Pull the interface module along the guide rails until it completely comes out of the switch
chassis.
When installing or removing an optional interface module, pay attention to the following points:
Do not touch the surface-mounted components directly with your hands.
Do not use too much force in the operation.
After removing an interface module, if no new module is to be installed, install the filler panel as
soon as possible to prevent dust and ensure the normal ventilation in the switch.

Connecting Optical Fiber

After a switch starts, the optical port may emit invisible radial when there is no optical connector
connected to it and the protective cap is removed from it. Therefore, do not stare into the optical
interface.
Be sure to cover the protective cap within 10 seconds if an optical connector is not in use to keep
the optical connector clean.
Be sure to cover the protective cap if an optical port has no optical connector attached.
Place the protective caps in a safe place when an optical port has fiber connected to prepare for the
cases the fiber is pulled out.
