Installing the Switch

Before installing the switch:

1.Unpack the switch.

2.Choose a location near the devices to be connected and close to an electrical outlet.

3.Proceed to “ Installing the BayStack 70 Series 10/100 Ethernet Switch on a Flat Surface” or “ Mounting the BayStack 70-24T 10/100 Ethernet Switch in a Rack.”

Installing the BayStack 70 Series 10/100 Ethernet Switch on a Flat Surface

The BayStack 70 Series 10/100 Ethernet Switch can be mounted onto any appropriate flat, level surface that can safely support the weight of a switch and its attached cables, as long as there is adequate space around the unit for ventilation and access to cable connectors.

Caution: When the BayStack 70 Series 10/100 Ethernet Switch is installed in a stack on a shelf or tabletop, the accumulated weight of the port cables increases with the height of the shelf or tabletop.

To install the switch on a desktop or any other flat surface:

1.Install the self-adhesive rubber pads on the bottom of the switch.

Peel off the protective backing from the rubber pads and apply one at each marked location on the bottom of the switch.

2.Set the switch on a desktop or any other flat surface.

For proper ventilation, make sure that the switch has at least 2 inches (5.1 cm) of space on each side and 5 inches (12.7 cm) of space at the back.

Caution: Restricted airflow could cause overheating of the components. Be sure to provide adequate ventilation space on the sides and rear of the switch.
