Status Displays
The GB-750 has seven LEDs on the front panel, indicating power, connec-
tivity and activity. When the red GTA logo on the front panel of the GB-500
is lit, the GB-750 is powered on. Two groups of three LEDs labeled 0, 1 and 2
correspond to the network interfaces; the amber LEDs blink whenever activity
at any speed is detected by the rewall, while the green LEDs will be lit
whenever the network interface is connected.
Three sets of lights on the back panel correspond to the indicator lights on the
front, except that the colors are reversed: amber is link and green is activity.
Warning
There are no user serviceable parts in the GB-750. Opening the unit
will void the warranty on the system.
