If no protection switching is provided, the Main unit
plugs into any odd-numbered slot. The next higher
even-numbered slot may contain a blank card or can
be left empty. See Figure 2.
Installing the QFO-C
1. Set the right switch segment S2-2 to Working
“on” or Protect “off” depending on where the
QFO-C is to be located (even- or odd-numbered
slot).
• Odd-numbered slot - set to Working
• Even-numbered slot - set to Protect
NOTE
The left switch segment S2-1 should be in the
“off” position.
2. Plug the transmit and receive fiber cables into the
fiber optic transceiver (U8) and route the cables
as shown in Figure 3.
CAUTION
For proper operation, the ends of the fiber cables
must remain clean. Do not touch the ends of the
cables. When routing the cables, make sure the
cables have no sharp bends.
3. Position the QFO-C into the selected shelf slot.
While holding the fiber cables between the two
cable guides on the top of the QFO-C front panel,
lower the card retention lever and slide the unit
into the shelf assembly.
