!Four rubber foot pads

!Stack cable

!Rack mount bracket kit

!AC power cord

!This installation guide

!Warranty card

Prior to installing your hub, make sure you observe the following cabling and installation environment requirements. The hub can be placed directly on your desktop or mounted in a rack.

!Do not plug a phone jack connector into any RJ-45 port. This may damage the hub. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

!Make sure each twisted-pair cable does not exceed 100 meters (328 feet).

!Allied Telesyn recommends using Category 5 cable for all network connections to avoid any confusion or inconvenience in the future when you upgrade attached devices to Fast Ethernet.

!Power requirements: 100 to 240 VAC ± 10% at 50 to 60 Hz ± 3Hz. The hub's power supply automatically adjusts to the input voltage level.

!The hub should be located in a cool, dry place, with at least 10 centimeters (4 inches) of space at the front and back for ventilation.

!Place the hub out of direct sunlight, and away from heat sources or areas with a high amount of electromagnetic interference.

!If you intend to mount the hub in a rack, make sure you have all the necessary mounting screws, brackets, bolts and nuts, and the right tools.

!Check if network cables and connectors needed for installation are available.
