SpectraLink 6300 MCU: Facility Preparation

Install Intershelf Junction Panel

The Intershelf Junction Panel (JPI300) is to be installed only in restricted access areas (dedicated equipment rooms, equipment closets, or the like), in accordance with Articles 110-16, 110-17, and 110-18 of the NEC, ANSI/N FPA 70.

The expansion shelf controllers of shelves 2 through 20 are connected to the system controller by an intershelf junction panel. The panel converts the RJ-21 connections on the system controller to the RJ-45 connections on the expansion shelf controller.

Install the panel in the rack or on the wall adjacent to the Primary Shelf, which contains the system controller (CSC306 or CSC320).

Wall mounting requires 1.75” #8 panhead wood screws. The panel must be mounted with standoffs at least 1.5” long and 1/4” inside diameter.

Connect Power to Shelves

Polycom recommends that a licensed electrician install the -48V DC power supply and connect power to the shelves.

When connecting the -48 V DC system to power, note the following precautions:

A 30 amp circuit breaker must be present on the non-grounded DC circuit conductor, and the installer must ensure that means are provided for connection of the equipment to the DC source by permanent wiring methods, and no disconnecting device is located in the grounded DC circuit conductor between the point of connection to the supply and the point of connection to the grounding electrode and equipment grounding conductors.

The DC input to the power supply is polarity sensitive. Incorrect hookup will prevent normal operation of the system and may cause damage. Double check polarities before making any connections. Verify that the DC power switch on each shelf is OFF.
