Prepare for Fiber Routing – Remove the Front Door of the Cabinet

Use a screwdriver to loosen the ground screw at
1
the bottom of the cabinet door and disconnect the
cabinet door from the ground cable. The removed

recommended that you use flexible materials such as
foam to protect the cabinet door from scratches.
2
Hold and pull down the lock rod on the upper part
2
of the cabinet door to separate the rotating shaft
from the cabinet (ensure that the cabinet door
does not fall down), and then lift and remove the
cabinet door.

If the front door of the cabinet has been removed,
skip this step.
