Status LEDs
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.
External Power
The SeaI/O-270U includes an industrial grade wall-mount power supply (Item#
TR122) that outputs 12VDC @ 2A. 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.
