Opening and Closing the Housing

Overview

Installation or maintenance of the Model GS7000 Optical Hub requires opening the
housing to access the internal modules.
Proper housing closure is important to maintaining the node in good working
condition. Proper closure ensures a good seal against the environment, protecting
the internal modules.

Opening the Housing

Open the housing as follows.
1 Remove the bolts securing the lid to the base.
2 Carefully open the lid to allow access to the inside of the housing.
3 Inspect gaskets on the cover flange and on the test port plugs.
4 Replace any gaskets showing signs of wear (cracked, twisted, pinched, or dry)
with new, silicon-lubricated gaskets.

Closing the Housing

Close the housing as follows.
1 Ensure any worn gaskets are replaced, and the gaskets are clean and in the
correct position.
2 Carefully close the lid.
3 For strand-mounted housings, pull the lid away from the base and remove the
slack from the hinge before rotating the lid up toward the base.
4 Ensure no cables are pinched between lid and base.
5 Secure lid to base with bolts. Tighten from 5 to 12 ft-lbs (6.8 to 16.3 Nm) in the
sequence shown in the following illustration. Repeat the sequence twice,
ending with the final torque specification.

CAUTION:
Use caution when closing the housing. Improper closing may result in the unit
not being sealed from the environment.
