Mounting the Hub

This hub can be placed directly on your desktop, or mounted in a rack.

Before you start installing the hub, make sure you can provide the right
operating environment, including power requirements, sufficient physical
space, and proximity to other network devices that are to be connected. Verify
the following installation requirements:

· 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 cm. (4 in.) 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.
