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 

 for an illustration of cable routing 

from the CyberData 4-Port PoweredUSB 2.0 Hub.

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.
