Installing a Protection Mounting Frame
The modular design of the cabinet's copper line protection system allows you to
incrementally expand line capacity. Protection blocks are housed in mounting frames that
install on the 43-inch rack in the copper splice compartment. Each mounting frame holds up
to ten 50-pair protection blocks. Since ten protection blocks are required to support a fully
equipped C7 shelf (480 lines), one protection mounting frame is required per C7 shelf.
You can field-install protection mounting frames to expand system capacity.
To install a protection mounting frame
1.
Unpack the protection mounting frame from the shipping packaging.
2.
Verify that two ground wires are connected to the mounting frame. Install the ground
wires if necessary.
3.
Mount the protection mounting frame onto the rack as follows:
a.
Turn the two knobs on the frame counter-clockwise to the open position.
b.
Attach the mounting frame to the rack using four supplied self-tapping screws.
c.
While holding the top of the mounting frame against the rack, turn the two knobs
clockwise to secure the frame to the rack in the closed position.
4.
Route the two frame ground wires to the main ground bar (located at the bottom of the
splice compartment). Attach the ground wire lugs to any open position on the main
ground bar.
