Installing 5-Pin Protection Modules
To complete the circuit connections between the metallic outside plant cables and equipment cables, you must install 5-pin
protection modules into the protection blocks. The 5-pin modules serve as fuses to protect the equipment from electrical
surges on the lines.
Each protection block protects 48 pairs with each 5-pin position on the block protecting one wire pair (one 2-wire circuit or
half of a 4-wire circuit). Install a 5-pin protection module into each position on the protection block that shall be equipped for
service. Use black modules for T0 circuits and red modules for T1 circuits. Refer to the cabinet pair assignment list for more
information.
