IV. Power Mode Setting
There are two power mode options for the GE
“Executive Series” USB 2.0 4-Port Hub.
The rst is self-power mode (recommended),
which requires the use of the AC power
adapter. In this mode, each port is provided
with 500 milliamps, allowing for additional
hubs, cameras and other high-powered
devices.
The second is bus-power mode, which does
NOT require the use of the AC power adapter.
In this mode, the hub is provided with 500
milliamps for all 4 ports. This should be
adequate for mice, keyboards, and other low
power devices. If you are not sure or if device
performance is poor, use the AC adapter.
When using the AC power adapter, make
sure the plug is properly connected to the hub
and to a standard electrical outlet. GE Surge
protection is recommended.
