Connect to an External Alarm-Reporting Device
You can connect the router to external alarm-reporting devices through the relay contacts on
the craft interface next to the LEDs labeled

RED ALARM
and
YELLOW ALARM
(see Figure 47). A
system condition that triggers the red or yellow alarm LED on the craft interface also
activates the corresponding alarm relay contact.
activates the corresponding alarm relay contact.
The alarm relay contacts accept wire of any gauge between 28-AWG and 14-AWG (0.09 and
2.09 mm
2.09 mm

) wire, which is not provided. Use the gauge of wire appropriate for the external
device that you are connecting to the contacts.
To connect an external device to an alarm relay contact, follow this procedure:
1.
Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.09 and
2.09 mm

).
2.
Use a 2.5 mm Phillips screwdriver to loosen the small screws on the faceplate of the
appropriate alarm relay contact—the upper contact for a device that reports high priority
(red) alarms, or the lower contact for the device that reports lower priority (yellow)
alarms.

3.
Insert wires into the appropriate slots in the front of the relay contact (
NC
means
“normally closed,”
C
means “common,” and
NO
means “normally open”).
4.
Attach the other end of the wires to the external device.
Connect PIC Cables
Now plug network cable into the PICs housed in the FPCs. For information about the cable
used by the PICs supported on the M40 router, see the M20 and M40 Internet Routers PIC
Guide.

To connect the PIC cables into the PIC cable connectors at the front of the chassis, follow this
procedure:
procedure:
1.
Have ready a length of the type of cable used by the PIC.
2.
If the PIC cable connector port is covered by a rubber safety plug, remove the plug.
3.
Insert the cable connector into the cable connector port on the PIC faceplate (see
Figure 50, which shows a fiber-optic connector).

Do not look directly into the ends of fiber-optic cables or
the transceivers on the faceplate of a PIC that connects to
fiber-optic cable. Single-mode fiber-optic cable and the
PICs that use it (such as ATM or SONET/SDH) emit laser
light that can damage your eyes.

Do not leave a transceiver uncovered except when
removing or inserting the cable. The safety cap keeps the
port clean and prevents accidental exposure to laser light.
