existing expansion cabinet 1 to the daughterboard in connector
"Fiber 1" and cabinet 2 to the daughterboard in connector "Fiber
2." Make sure you have labeled and connected the cables, as
shown in Table 3.
— If you use two dual port expansion daughterboards, connect
the first expansion cabinet 1 to the top connection on the
daughterboard in connector "Fiber 1." Connect cabinet 2 to the top
connection on the daughterboard in connector "Fiber 2." Make
sure you have labeled and connected the cables from the
expansion cabinets as shown in Table 3 on page 104
— If you use one dual port expansion daughterboard, connect
the first expansion cabinet 1 to the top connection on the
daughterboard in connector "Fiber 1." Connect cabinet 2 (the
existing expansion cabinet) to the bottom connection on the
Option 11C and 11C Mini
