1.13.1 Card Slot Requirements
The ONS 15454 SDH shelf assembly has 17 card slots numbered sequentially from left to right. Slots 1
through 6 and 12 through 17 are for traffic-bearing cards.
Slots 7 and 11 are dedicated to TCC2/TCC2P cards. Slots 8 and 10 are dedicated to cross-connect
(XC-VXL-2.5G, XC-VXL-10G, XC-VXC-10G) cards. Slot 9 is reserved for the optional AIC-I card.
Slots 3 and 15 can also host electrical protect cards that are used in 1:N protection.
Caution Do not operate the ONS 15454 SDH with a single TCC2/TCC2P card or a single
XC-VXL-2.5G/XC-VXL-10G/XC-VXC-10G card installed. Always operate the shelf assembly with
one working and one protect card of the same type.
Shelf assembly slots have symbols indicating the type of cards that you can install in them. Each
ONS 15454 SDH card has a corresponding symbol. The symbol on the card must match the symbol on
the slot.
Table 1-5 shows the slot and card symbol definitions.
