Sneak Fuse Panels; Cable Installation - Avaya MCC1 Installation And Upgrades

Sneak Fuse Panels

Sneak current protection is required between the incoming RJ21X or RJ2GX network interface and the
system for both trunk and off-premise circuit packs.
The Model 507B sneak current fuse panel, or equivalent, is recommended for sneak current protection.
The panel contains two 25-pair connectors, fuse removal tool, and fifty 220029 sneak fuses (and two
spares).
Connector cables (B25A male to female) connect the network interface to the sneak fuse panel. Also,
157B connecting blocks equipped with SCP-110 protectors can be used for sneak current protection.
NOTE:
Sneak current protectors with a rating of 350 mA at 600 volts must be Underwriter's
Laboratory (UL) listed for domestic (USA) installation and Canadian Standards
Association (CSA) certified for Canadian installation.
•
The 507B includes 52 sneak fuses and two cables.
•
The SCP-110 protectors are used with 110-type hardware and on the 507B Sneak Fuse Panel. The
SCP-110 Protectors can be ordered separately and installed on the 157B connecting block. Fifty
protectors are required per block.

Cable Installation

NOTE:
To route the cables from the rear of the SCC1 stack or MCC1 to the MDF, use the
