3.Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

4.Use caution when installing or modifying telephone lines.

5.This equipment is intended to be used behind devices that provide primary lightning protection.

For 1:1 Automatic Protection Switching (APS), two identical units are installed into adjacent slots. The Main unit plugs into any odd-numbered slot and its Auxiliary unit plugs into the next even-numbered slot to the right.

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 ÒonÓ or Protect ÒoffÓ 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 ÒoffÓ 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.
