Chapter 1 Hardware Installation
Card Installation
Slots 3 and 15 can host E1N-14 and DS3i-N-12 cards that are used in 1:N protection.
Note Do not operate the ONS 15454 SDH with a single TCC-I card or a single XC10G card installed.
Always operate the shelf assembly with one working and one protect card of the same type.

slot. Table 1-7 shows the slot and card symbol definitions.
Table 1-8 lists the number of ports, line rates, connector options, and connector locations for ONS 15454
SDH optical and electrical cards.
