Description
Update the chapter “Add a Network Group to Option 81C with FNF” to “Add
a Network Group to Option 81C CP2-4 with FNF” and include Option 81C
CNI group assignments on a system that originated as a non-FNF system
prior to X11 Release 25.
Correction
Note: Figure, table, procedure, and page numbers (for example, Table 5,
page 10) are subject to change in the next standard release of documentation.

Preparing for installation
The procedures in this section are for systems that have already been
upgraded to the Fiber Network. Follow the procedures in order.
Verifying removal of 3PE cards from Option 81 Core shelves
In Option 81 systems, the 3PE card must be removed from the Core shelves.
This card should have been removed during the upgrade procedure. If this
card was not removed during the upgrade process, remove it now.
Note: This procedure is for Option 81 systems with Core shelves. This
procedure is NOT necessary for Option 81C systems with Core/Net
shelves.
Procedure 1
Removing the 3PE card from both Cores:
1In Core 1, hardware disable the 3PE card.
2In Core 0, hardware disable the 3PE card.
3Remove the 3PE faceplate cable.
4Remove the 3PE cards from Core 1 and 0.
—————————— End of Procedure ——————————
Add the new Network modules
The new Network modules must be connected to the system. Follow the
instructions in System Installation Procedures (553-3001-210) to correctly
configure the power and System Monitor connections.
Add CNI cards if necessary
CNI-3 cards are added only if additional ports are required. CNI-3 cards can
only be installed in an inactive Core module.
Port assignments
The default port assignments for CNI cards in Option 81 and 81C systems are
shown in Table 1 and Table 2. These assignments can be modified in
Overlay 17 if necessary.

Documentation Release Note Number: MER-1002-003
Nortel Networks11/4/024of 26
TM
When a two port CNI card is replaced with a three port CNI-3 card, the
original port assignments for the backplane connections remain the same.
Procedure 2
Installing the CNI-3 cards
1On the inactive Core, software disable the CNI slots where the new
cards will be installed:.
2Faceplate disable the CNI cards to be replaced on the inactive Core.
3Remove the CNI cards to be replaced, if necessary.
4Install the new CNI-3 cards. The CNI-3 cards must be faceplate
disabled before installation.
5Faceplate enable all CNI cards on the inactive Core.
—————————— End of Procedure ——————————
Procedure 3
Adding a CNI group
1Add CNI group(s).
2Software enable the original CNI ports on the inactive Core. Do NOT
activate the CNI ports for the new Network Groups:.
3Switch active Cores:
4Follow steps 1 and 2 to install the CNI cards on the second Core. Be
sure to make the second Core inactive.

5Verify the status of the CNI cards:
—————————— End of Procedure ——————————
Pre-routing CNI to 3PE cables
The CNI backplane ports are connected to the 3PE cards with two NTND14
CNI to 3PE cables per port. The third port connects from the CNI-3 faceplate
to the 3PE card with two NT9D89 cables.
When a CNI card is upgraded to a CNI-3 card, the original NTND14
backplane cables are left in place; only the NT9D89 CNI-3 to 3PE faceplate
cables must be added.
Procedure 4
Pre-routing CNI to 3PE cables
1Label the cables with Network Group, CNI port and connection
information.
2Route the new CNI to 3PE cables according to the port assignments in
Tables 1, Table 2 and Table 3. Do NOT attach the cables.
—————————— End of Procedure ——————————
STAT CNI to check the status of the cards and ports.

Installing and enabling 3PE cards
1Verify the 3PE card settings.
The group and shelf number of each Network module is determined by
the switch settings on the 3PE card. Use the information in Table 6 on
page 18 to verify that the 3PE cards in the new Network modules have
the correct switch and jumper settings.
This group and shelf setting is displayed on the FIJI card display.
2Install a 3PE card in slot 1 of each new Network module. Push the
latches forward to lock the card in place.
3Attach the cables to the inactive 3PE faceplates.

Enabling the CNI cards
If new CNI-3 cards are required, they must be installed before the cards are
enabled. See “Add CNI cards if necessary” on page 3 to install the cards.
Note 1: If you are adding more than one Network Group, it is
recommended that you add one group at a time in software. Follow all
the remaining procedures in this chapter to complete the addition of one
group before starting to add another group.
Note 2: CNI cards can be enabled and connected on the inactive Core
only.
Follow Procedure 12 to connect and activate the new CNI ports.
Procedure 12
Connecting and activating CNI ports
1Verify that the cables are correctly routed, labeled, and connected to
the 3PE cards. See “Pre-routing CNI to 3PE cables” on page 5.
2Attach the cables to the inactive CNI cards.
See Table 1, “Option 81 CNI group assignments,” on page 6, Table 2,
“Option 81C CNI group default assignments (introduced with X11
25.xx),” on page 7 and Table 3, “Option 81C CNI group assignments
on a system that originated as a non-FNF system prior to X11 Release
25,” on page 8 for connection information.
3Software enable the new CNI ports on the inactive Core.
CAUTION
Damage to Equipment
The backplane connector pins are easily bent. Install
backplane cables with extreme caution to ensure that
these pins are not damaged. Carefully line up the cable
and press it into place. Never force a cable into the slot.
If the cable gets stuck, remove it and try again. Damage
to the backplane connector pins can make installation of
CNI cables impossible.
