Connecting a Multi-Shelf Node
To connect a three shelf node in a splitter configuration where the OSC modules are added and dropped
on each shelf, follow these steps:
Step 1 Connect the cables of the first OADM module in slot 0 of shelf A as follows:
a. Connect the OSC IN port of the OADM to the TX port of the OSC module.
b. Connect the OSC OUT port of the OADM to the RX port of the OSC module.
c. Connect the MID_IN port of the first OADM on shelf A to the MID_OUT of the second OADM on
the shelf A.
d. Connect the MID_OUT port of the first OADM on shelf A to the MID_IN of the second OADM on
the shelf A.
e. Connect the TRUNK_IN port and the TRUNK_OUT port of the first OADM on shelf A to the west
side trunk.
Step 2 In addition to the cables already connected to the second OADM module in slot 0 of shelf A, make the
following connections:
a. Connect the OSC IN port of the OADM to the TX port of the OSC module.
b. Connect the OSC OUT port of the OADM to the RX port of the OSC module.
c. Connect the TRUNK_IN port of the second OADM on shelf A to the TRUNK_OUT port of the first
OADM on shelf B.
d. Connect the TRUNK_OUT port of the second OADM on shelf A to the TRUNK_IN port of the first
OADM on shelf B.
Step 3 In addition to the cables already connected to the first OADM module in slot 0 of shelf B, make the
following connections:
a. Connect the OSC IN port of the OADM to the TX port of the OSC module.
b. Connect the OSC OUT port of the OADM to the RX port of the OSC module.
c. Connect the MID_IN port of the first OADM on shelf B to the MID_OUT of the second OADM on
the shelf B.
d. Connect the MID_OUT port of the first OADM on shelf B to the MID_IN of the second OADM on
the shelf B.
Step 4 In addition to the cables already connected to the second OADM module in slot 0 of shelf B, make the
following connections:
a. Connect the OSC IN port of the OADM to the TX port of the OSC module.
b. Connect the OSC OUT port of the OADM to the RX port of the OSC module.
c. Connect the TRUNK_IN port of the second OADM on shelf B to the TRUNK_OUT port of the first
OADM on shelf C.
d. Connect the TRUNK_OUT port of the second OADM on shelf B to the TRUNK_IN port of the first
OADM on shelf C.
