When a card is inserted in a card slot, it will contact the shelf backplane but is not fully installed until
the ejectors are fully closed.
1.11.1 Card Slot Requirements
The ONS 15600 SDH shelf has 14 card slots numbered sequentially from left to right. Slots 1 to 4 and
11 to 14 are reserved for optical (STM-N) traffic cards. These slots can host any of the ONS 15600 SDH
optical cards. Slots 6/7 and 8/9 are dedicated to SSXC cards, and Slots 5 and 10 house the TSC cards.
Each card is keyed to fit only in an appropriate slot for that card. Unused card slots should be occupied
by a filler card (blank faceplate).
Do not operate the ONS 15600 SDH with a single TSC card or a single SSXC card installed. Always
Caution
operate the shelf with one active and one redundant standby TSC card and two SSXC cards.
Shelf assembly slots have symbols indicating the type of cards that you can install in them. Each
ONS 15600 SDH card has a corresponding symbol. The symbol on the card must match the symbol on
the slot.
