Power-Up
In order to minimize the possibility of accidental power shut off to the OmniMux 400,
no power switch has been designed into the product. Special care must be taken
when applying power to the OmniMux unit.
WARNING
The OmniMux unit does not have a power switch,
so extra care must be taken in powering the unit.
Always plug the Power Adapter into the back of
the Mux unit first. This is in order to prevent
damage to the Mux unit and to prevent potential
shorts, sparks, and fire hazards.
Verify that the power supply voltage (by reading the label on each power adapter
unit) is consistent with the facility’s line voltage (115/230 Volts), and that the Power
Adapter plug fits in the outlet.
Plug the Power Adapter’s cable connector to the appropriate matching connector
in the back of the OmniMux Unit.
Plug the Power Adapter into the wall outlet. Observe that all LED’s light up for
approximately 0.5 seconds. After 0.5 seconds, all should extinguish except the
yellow power LED; It stays On.
Control Switches
The following figure depicts a rear view of the OmniMux 400. There are two Switch
Banks which control the operation of the OmniMux 400.
