To connect an external device to an alarm relay contact:
1.
Prepare the required length of wire with gauge between 24-AWG and 12-AWG (0.20
and 3.33 mm
2
).
2.
While the terminal block is not plugged into the relay contact, use a 2.5-mm flat-blade
screwdriver to loosen the small screws on its side. With the small screws on its side
facing left, insert wires into the slots in the front of the block based on the wiring for
the external device. Tighten the screws to secure the wire.
3.
Orient the terminal block according to the labels to the left of the appropriate relay
contact (
NC
means “normally closed,
C
means “common,” and
NO
means “normally
open”).
4.
Plug the terminal block into the relay contact and use a 2.5-mm flat-blade screwdriver
to tighten the screws on the face of the block.
5.
Attach the other end of the wires to the external device.
If attaching a reporting device for the other kind of alarm, repeat the procedure.

Connecting the M40e PIC Cables
After installing the router into the rack as described in “Installing the M40e Router Using
a Mechanical Lift” on page 81 or “Installing the M40e Chassis into the Rack” on page 95,
complete the installation by connecting management and alarm devices, PICs, and power
cables.
Now connect PICs to the network by plugging in network cable. To connect cable to the
PICs (see Figure 69 on page 117, which shows a fiber-optic PIC):
1.
Have ready a length of the type of cable used by the PIC. For cable specifications, see
the
M40e Multiservice Edge Router PIC Guide
.
2.
If the PIC cable connector port is covered by a rubber safety plug, remove the plug.
WARNING:
Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION:
Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
