Status LEDs are also included on the front of the SeaI/O-270U module to indicate the following
information:
ENABLE
(Yellow) – Lights when the USB hub is enumerated by the host system.
FAULT
(Red) – Lights when there is a problem with a downstream USB port. Disconnect
the downstream devices one at a time until the status returns to normal.
EXT POWER
(Green) – Indicates the external power supply is properly connected to the
hub and an AC power source.
The SeaI/O-270U includes an industrial grade wall-mount power supply (Item#
TR123
) that
outputs 12VDC @ 2.5A. Power is input via a 5mm 2-position removable screw terminal block
(shown below). To prevent accidental disruption of power, the terminal block includes mounting
screws for securing to the hub.
