Connecting the MX2008 to the Network

Tools and Parts Required for MX2008 Router Connections

To connect the router to management devices and MPCs, you need the following tools and parts:

To connect the alarm relay wires between a router and an alarm-reporting device (see Figure 1):

Prepare the required length of replacement wire with gauge between 28 AWG (0.08 mm²) and 14 AWG (2.08 mm²).
Insert the replacement wires into the slots in the front of the block (see Table 1). Use a 2.5-mm flat-blade screwdriver to tighten the screws and secure the wire.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
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.
Attach the other end of the wires to the external device.

Function No.	Label	Description
1	MINOR ALARM—[NC C NO] MAJOR ALARM—[NC C NO]	The alarm relays consist of three terminal contacts with a normal closed (NC), a common (C), and a normal open (NO) relay that signal a minor or major alarm when broken.

To disconnect the alarm relay wires from the router and an alarm-reporting device (see Figure 2):

Disconnect the existing wire at the external device.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
Using a 2.5-mm flat-blade screwdriver, loosen the small screws on the face of the terminal block and remove the block from the relay contact.
Using the 2.5-mm flat-blade screwdriver, loosen the small screws on the side of the terminal block. Remove existing wires from the slots in the front of the block (see Table 2).

To connect the MPCs or MICs to the network (see Figure 3):

Have ready a length of the type of cable used by the component. For cable specifications, see the MX Series Interface Module Reference.
Remove the rubber safety plug from the cable connector port.
Laser 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.
Insert the cable connector into the cable connector port on the faceplate.
Arrange the cable in the cable manager to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on the loop helps to maintain its shape.
CAUTION:
Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

CAUTION:
Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.
