The following tables show examples of how Side IDs are automatically assigned by the system for
common DWDM layouts.
Table 9-2 shows a standard ROADM shelf with Sides A and B provisioned. The shelf is connected to
seven shelves containing TXP, MXP, ADM-10G, GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards.
Table 9-3 shows a protected ROADM shelf. In this example, Side A and B are Slots 1 through 6 in
Shelves 1 and 2. 40-WSS-C/40-WSS-CE/40-DMX-C or 40-WSS-CE/40-DMX-CE cards are installed in
Sides A and B. Slots 12 through 17 in Shelves 1 and 2 contain TXP, MXP, ADM-10G, GE_XP,
10GE_XP, GE_XPE, or 10GE_XPE cards.
Table 9-4 shows a four-degree mesh node. Side A is Shelf 1, Slots 1 through 6. Side B and C are Shelf 2,
Slots 1 through 6 and 12 through 17, and Side D is Shelf 3, Slots 1 through 6. 40-WXC-C cards in line
termination mode are installed in Sides A through D.
