the front panel: a green power LED, a red network activity LED,
and four red peripheral port activity LEDs. The
POWER

illuminate when the unit has power applied to it. The
RX/TX

will illuminate when the unit detects activity on the network. When
the unit receives a print job to send to a printer or a network user
has a connection to a modem, the LED for the target peripheral will
illuminate (

The PS-MIO has one network activity LED which will illuminate
whenever activity is detected on the network.
All 10BASE-T models have a
LINK
LED on the back panel which
will illuminate if there is a good connection between the BayTech
print server and the hub.
