Installing external cables

553-3001-250 Standard 14.00 August 1996
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 NT8D86 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 NT8D73 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.
• Connect the NT9J98 cable from the faceplate connector of the
peripheral buffer to the I/O panel connector at the top or the side of
the cabinet.
2 Install alarm cables as outlined in "System monitor upgrade installation"
on page 13-1.
3 Connect the external cable from the Core/Network module I/O panel
connector (labeled "PRI/DTI") to the network interface.
4 Install one PRI/DTI card in this module as the primary clock reference
and install the rest of the PRI/DTI cards in the peripheral cabinet CE
shelf. For installation procedures, refer to Circuit card installation and
testing (553-3001-211).
5 Verify that the PRI/DTI cards in the peripheral cabinet CE shelf are
connected to the MDF.
6 Connect all external cables from the MDF to the PE shelf connectors on
the cabinet I/O panels and the IPE module I/O panels. Refer to the
appropriate procedure in Meridian 1 system installation procedures
(553-3001-210) for IPE module cabling procedures.
