Installing external cables

14 If you are not going to use network shelves for PRI/DTI cards, do the
following:
• Disconnect alarm connectors from the harness to network shelves.
• Unplug all power converter cards from each network shelf.
• Disconnect power connections and the power monitor connector
from the cabinet power distribution harness to the backplane on
QSD39 and QSD40 shelves.
• Tape all exposed power leads with electrical insulation tape.
Now that the option 61C column is installed and the peripheral cabinet has
been prepared, you must connect them with external cables.
1 Install network cables between the peripheral cabinet and the new
modular column. This connects network cards in the Core/Network
module to the peripheral buffer card in the PE shelf of the cabinet. Refer
to Upgrade engineering (553-3001-150) for a detailed explanation of the
connector kits and cables required to connect peripheral shelves in a
cabinet to an option 61C column.
Each network loop connection requires that three cables be installed:
• Connect the NT8D86AC cable from the faceplate connector of the
network card to the I/O panel connector at the rear of the
Core/Network module.
• Connect the NT9J96 cable (up to 16 feet in length) from the I/O
panel connector on the Core/Network module to the I/O panel on the
top or the side of the peripheral cabinet. A connector housing kit is
required for the cabinet to accept the cable connector.
• Connect the NT8D86AC cable from the faceplate connector of the
peripheral buffer to the I/O panel connector at the top or the side of
the cabinet.
