M7i Internet Router Quick Start

CAUTION: To prevent damage to fiber-optic transceivers and fiber-optic cables, observe the following precautions:

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

■Do not bend fiber-optic cable beyond the maximum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

■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.

1.Make sure you have the appropriate cable for the FIC or PIC.

2.If you are connecting to a FIC or PIC with removable transceivers, make sure the transceiver is installed.

3.If the transceiver is covered by a rubber safety plug, remove the plug.

4.If the cable connector is covered by a rubber safety cap, remove the cap.

5.Insert the appropriate cable connector into the cable connector port on the FIC or PIC faceplate.

6.Arrange the cable in the cable management system 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 in the cable management system. Placing fasteners on the loop helps to maintain its shape.

Step 5: Connect Ground and Power Cables

NOTE: Connect each power supply to a separate external power source.

The M7i router uses either AC or DC power supplies. Perform the appropriate procedure for each power supply in your router.

■Connect DC Power on page 11

Connect AC Power

1.Locate the power cords shipped with the router, which should have a plug appropriate for your geographical location.

2.Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
