2. Position the MCS300 so that the six mounting screws are aligned with the six
keyhole openings in the back of the shelf.
3. Slide the shelf down onto the screws to lock the shelf into place. Check that all
six screws are properly locked.
4. Tighten all six screws fully.
Do not install cards until power is connected.
5.4 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.
5.5 Connect Power to Shelves
SpectraLink 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.
Run Conduit To Shelf
The shelves have two possible points of entry for conduit: on the side, used for wall
mounted shelves, or in the rear, used for rack mounted shelves.
