Dac I/O Panel - Toshiba VP 300 Installation Instructions Manual

To mount the power supply:
1. Screw the two upper screws (#10 or #12 by 3/4 inches) all but 1/8 inch of the thread
into the backboard. Place the screws 6-1/2 inches apart.
2. Hang the power supply on the screws and then tighten the screws.
3. Screw in the two lower screws to complete the mounting procedure.
I Attach the Telephony Ground
The power supply harness consists of a jacketed, 3-conductor cord and a separate 14-gauge
ground wire (green and yellow in color). The ground wire is to be connected to the building
telephony ground.
Remove any insulation from the contact areas before connecting or splicing the wires.
The connection at the telephony ground point may require one or more special clamps. This
is determined on a site-by-site basis.
I Install DAC Cards
Plug the DAC into the VP 300 cabinet. Since the DAC is hot-pluggable, the VP 300 need
not be powered OFF to do this. Verify that the cards are plugged into those slots
configured for the DAC, as described previously.
Up to eleven DAC cards may be installed in a VP 300 cabinet for a total of 44 DID or
special service trunks. Standard LICs and DACs may be mixed in a system. However, the
DAC cannot reside in slot A12.
