Pull down the spring-loaded plunger latch on the right side of the protection block. While holding the plunger
down, rotate the block back into its mounting position. Release the plunger latch to secure it in the mounting
fixture.
c.
Install two supplied screws into the left side of the block to secure it to the frame. (The screws provide a
critical ground path to the cabinet's main ground bar or EXM's subground bar.)
Terminate the protection block interface cables as follows:
a.
Route the two RJ-21 equipment interface cables into the main compartment and connect to the Clearfield
service unit's RJ-21 connectors.
b.
Mate the two MS2 or 710 subscriber interface cables to the counterpart OSP interface cables.
c.
Dress and secure the interface cables to the rack or towel bars as needed.
Apply line identification labels over the protection block's dead pair positions (25, 50).
•
Use the blue labels to identify user lines (POTS/xDSL).
• If applicable, use the green labels to identify PSTN overlay lines.
Repeat Steps 1–6 to install additional protection blocks for lines served (adjacent to the first), as needed.
