Cni Configuration; Cable Installation Guidelines - Nortel Meridian 1 Manual

CNI configuration

In the NT5D21 Core/Net Module, port 0 on the NT6D65 Core to Network
Interface (CNI) Card in slot 12 must be configured as "group 0."
Communication between the CNI and 3PE cards for group 0 is accomplished
through the backplane; no cable is required.
Since only one network group is supported in option 61C, only one CNI card
is required. The CNI card must be installed in slot 12 in the Core/Net Module,
and Port 0 is dedicated to "group 0."

Cable installation guidelines

Core/Net module backplanes, like all circuit boards, have a primary side and
a secondary side. The primary side, which faces the front of the module,
contains the primary shrouds, which provide mechanical guidance for the
pins of the card edge connectors. The secondary side of the backplane, which
faces the rear of the module, contains the secondary shrouds, which provide
mechanical guidance for cable connectors.
The columns of secondary backplane shrouds are designated 18 through 12
from left to right (facing the rear of the backplane). This numbering matches
the card slots in the front of the module. The connector rows of secondary
backplane shrouds are designated A through F from top to bottom.
Before you connect cables to the backplane, visually inspect the backplane
shroud connectors to make sure there are no bent pins. To connect cables:
1 Orient the cable connector so the strain relief paddle is to the right.
2 Partially insert the cable connector so its guides mate to the
corresponding backplane connector.
3 Apply a small amount of pressure to push the cable connector straight
into the backplane connector. You will feel a detent click when the
connector seats.
Pins may be bent or broken if you try to insert the cable connector at
an angle. Do not push the connector in any further after you hear the
detent click.
