3 Repeat the process for the rack-mounting bracket on the other side of the

switch.

4 Insert the unit into the 48.26-cm (19-inch) rack, ensuring that the

rack-mounting holes on the switch line up to the mounting holes on the

rack.

5 Secure the unit to the rack with the rack screws (not provided). Fasten the

lower pair of screws before the upper pair of screws. Ensure that the

ventilation holes are not obstructed.

Installing on a Flat Surface

Install the switch on a flat surface if it is not installed on a rack. The surface

must be able to support the weight of the switch and the switch cables.

To install the switch on a flat surface:

1 Attach the self-adhesive rubber pads on each marked location on the

bottom of the chassis.

2 Set the switch on a flat surface, leaving 5.08 cm (2 inches) on each side

and 12.7 cm (5 inches) at the back.

3 Ensure that the switch has proper ventilation.

Connecting the Switch to Power Supplies

Each switch in the stack must be connected to an AC power supply.

The power connectors are positioned on the back panel. Connecting a

Redundant Power Supply (RPS) or Modular Power Supply (MPS) is optional,

but recommended. The RPS or MPS connector is on the back panel of the

switch. The RPS is used for non-PoE switches and MPS is used for PoE

switches.
