Step 7 Route the fiber cable through the cable-routing channel and cutout on the appropriate side of the shelf
assembly, as necessary (Figure 15-35 on page 15-37).
Step 8 As needed, route slack fiber-optic cable around the round cable retainers in the fiber-storage tray
(Figure 15-38 on page 15-40).
Caution When you close the fiber-storage tray, the cables must not be pinched, and the cable bend radius must
be equal to or greater than the minimum radius that is recommended in your site specifications. As you
route each cable through the fiber-storage tray, make sure that adequate cable slack remains.
Step 9 Route the fiber cable out either side of the fiber-storage tray as necessary.
Step 10 Plug the other end of the cable into the TX port.
Note Cards display an SF LED after the OSC terminations are created (see the “NTP-G38 Provision
OSC Terminations” procedure on page 3-84) if transmit and receive fibers are not connected
correctly. For example, an RX port is connected to another RX port or a TX port is connected to
another TX port.
Step 11 Repeat 5 through 10 until you have connected the nodes according to the site plan.
Step 12 Return to your originating procedure (NTP).

Note Throughout this task, west refers to Slots 1 through 8, and east refers to Slots 10 through 17.
Note To avoid errors, connect fiber-optic cable in fiber connections so that the farthest slot to the right
represents the east port, and the farthest slot to the left represents the west port. Inter-shelf, line side
connections (connections that span between adjacent sites), should be made such that fiber connected to
an east port on one node connects into the west port on an adjacent node.
Step 1 Refer to the Cisco MetroPlanner Internal Connections table (see Table 3-1 on page 3-3) for your site
when completing connections. Before you begin connecting fiber-optic cabling for ROADM nodes, read
and understand the following rules:
Purpose This task gives instructions, rules, and examples for installing fiber-optic
cables on an ROADM node in a DWDM shelf.
