26CHAPTER 2: INSTALLATION AND SETUP

CAUTION: When using a rack mounting system, the switch must be mounted on a shelf or runners. The rack mounting brackets alone are not sufficient to support the weight of the switch. The rack mounting brackets are provided to ensure stability across the horizontal plane. If you stack switches, you must ensure that the shelf or runners are strong enough to hold the combined weight. Ensure that the ventilation holes are not obstructed.

After deciding where to install the switch, make sure that:

■The switch is accessible and cables can be connected easily.

■Water or moisture cannot enter the case of the unit.

■Temperature must be within the range of 0 to 40 °C (32 to 104°F).

■Air-flow around the unit and through the vents on the side of the case is not restricted. You should provide a minimum of 75mm (3 in.) clearance.

■No objects are placed on top of the unit.

■Units are not stacked more than four high if the switch is free-standing.

Configuration Rules The connectors, supported media types, and maximum distances for the for Ethernet Switch 9100 are described in Chapter 1.

Rack Mounting	The Switch 9100 is 2U high and will fit in most standard 19-inch racks.
	CAUTION: The switch should only be used in a rack if it is mounted on
	runners, a shelf, or a tray to support the weight. The rack mount kits
	alone are not sufficient to support the weight of the switch. The rack
	mount kits must not be used to suspend the switch from under a table or
	desk, or attach it to a wall.

CAUTION: Disconnect all cables from the switch before continuing. Remove all self-adhesive pads from the underside of the switch, if they have been fitted.
