Card Slot Requirements
The ONS 15454 shelf assembly has 17 card slots numbered sequentially from left to right. Slots 1 to 6 and 12
to 17 are multiservice slots that are used for electrical, optical, and Ethernet cards (traffic cards). Card
compatibility depends on the EIA, protection scheme, and cross-connect card type used in the shelf. Refer to
the Card Compatibility for more detailed compatibility information.
Slots 7 and 11 are dedicated to TCC2/TCC2P cards. Slots 8 and 10 are dedicated to cross-connect (XCVT,
XC10G, and XC-VXC-10G) cards. Slot 9 is reserved for the optional AIC-I card. Slots 3 and 15 can also
host electrical cards that are used for 1:N protection. (See the Electrical Card Protection for a list of electrical
cards that can operate as protect cards.)
Caution! Do not operate the ONS 15454 with a single TCC2/TCC2P card or a single
XCVT/XC10G/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
card has a corresponding symbol. The symbol on the card must match the symbol on the slot.
Table 1-29 shows the slot and card symbol definitions.
Note: Protection schemes and EIA types can affect slot compatibility.
