To connect an external device to an alarm relay contact (see Figure 82 on page 234):
1. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08
and 2.08 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. 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.
4. Attach the other end of the wires to the external device.
To attach a reporting device for the other kind of alarm, repeat the procedure.

Connecting the MX480 Router to a Network for Out-of-Band Management
To connect the Routing Engine to a network for out-of-band management, connect an
Ethernet cable with RJ-45 connectors to the ETHERNET port on the Routing Engine. One
Ethernet cable is provided with the router. To connect to the ETHERNET port on the
Routing Engine:
1. Turn off the power to the management device.
2. Plug one end of the Ethernet cable (Figure 79 on page 232 shows the connector) into
the ETHERNET port on the Routing Engine. Figure 78 on page 232 shows the port.
3. Plug the other end of the cable into the network device.
