You can install the Switch 7750 in a standard, 19-inch cabinet or on a workbench.

When you are ready to install the Switch 7750 in the cabinet:

1 Carry the switch to the front of the cabinet. At least two people are required to 

move the switch.

2 Put the switch on the tray or the guides and push it into the cabinet.

3 Fix the switch in the cabinet with the combination screw and floating nuts that are 

shipped with the switch.

To install the switch on a workbench, take the following precautions: 

■

Ensure that the workbench is smooth and stable.

■

Leave a heat-dissipation clearance in the front and back of the switch of more 
than 1 m (3 ft) and at least 0.8 meters (2.5 ft) away from the walls on the sides.

■

Do not put heavy objects on the switch.

To install the cabling rack:

1 Attach the rack brace to the left side of the chassis (opposite the fan frame).

2 Insert the wiring channel into the brace and fasten the screws.
