4 Disconnect cables from the MSU faceplate, release the locking devices,
and remove the MSU.
5 Disconnect the MSU shelf alarm connector.
6 Remove remaining cards from the CE shelf and store them in a safe
place.
7 Install the NT8D81 Power Regulation card into slot 2 of the CE shelf in
the ST cabinet.
After the option 61C columns are installed and the peripheral cabinet has
been prepared, you must connect them with external cables.
1 Install network cables between the SL-1 cabinet and the option 61C
modular column. These cables connect network cards in the
Core/Network module to the peripheral buffer card in the PE shelf in the
cabinet. 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 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 SL-1 cabinet. A connector housing kit is
required for the cabinet to accept the cable.
• 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 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 SL-1 cabinet CE shelf.
