1.17.1 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
"3.1.2 Card Compatibility" section on page 3-3
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
"7.1 Electrical Card
Protection" section on page 7-1
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 1-32
shows the slot and card symbol definitions.
