2.2 Installation

The CyberData 4-Port PoweredUSB 2.0 Hub is a tabletop unit with mounting feet that sit on a flat
surface.

2.3 Connections

This following topics provide illustrations and information on connecting the CyberData 4-Port
PoweredUSB 2.0 Hub to power supplies, the host, and peripheral devices.

2.3.1 Power supply

The PoweredUSB specification requires supplying +24V at 2.3A and +12V at 1.5A to each voltage
designated port. These requirements are met only if the power supply has sufficient wattage for this
amount of power.
The Epson PS180 brick and Dell printer power supply are examples of lower-cost alternate power
supplies that can be used with this Hub and peripherals requiring less power. Two power plug
receptacles are provided on the back of the CyberData 4-Port PoweredUSB 2.0 Hub to facilitate the
use of alternate power supplies.
The three-pin connector is normally used for the Dell and Epson Bricks. The four-pin connector is
used for a high-current power supply. See
CyberData 4-Port PoweredUSB 2.0 Hub.
CAUTION
Operations Guide
The P1 and P2 DC input jacks on the back of this Hub are for input only. Do not plug
power supplies into both input jacks simultaneously as equipment damage that might void the
product warranty could occur.
