Installing external cables

553-3001-250 Standard 14.00 August 1996
After the option 61C columns are installed and the option 51 column has been
prepared, you must connect them with external cables.
Note: Installing external cables between the option 51 and option 61C
columns is required only if the two columns are not positioned
side-by-side. If these columns are adjacent to each other, you must install
column spacer kits and route cables between the columns as outlined in
Meridian 1 system installation procedures (553-3001-210).
1 Install network cables between the option 51 column and the option 61C
column. These cables connect network cards in the Core/Network
module to the IPE Controller card in the IPE shelf of the option 51. Refer
to Upgrade engineering (553-3001-150) for a detailed explanation of
connector kits and cables required to connect network loops between a
cabinet and an option 61C column.
Each network loop connection requires three cables:
• Connect the NT8D88 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 NT8D98 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
IPE module.
• Connect the NT8D92 cable from the faceplate connector of the
peripheral controller to the I/O panel connector at the rear of the IPE
module.
2 Install alarm cables as outlined in "System monitor upgrade installation"
on page 13-1.
3 Connect the external cable to the Core/Network module I/O panel
connecting PRI/DTI to the network interface.
4 Install one PRI/DTI card in this module to be the master card and install
the rest of the PRI/DTI cards, as slaves, in the option 51 CPU/Network
shelf.
