3.4 Powering On the Unit
Plug the appropriate end of an AC
power cord into the power input
port labeled 120 VAC on the back of
the unit. Plug the other end into its
proper power source.
The Lineshare Master-4 begins a
self-test soon after power is applied.
When the Lineshare completes its
self-check, the PORT LEDs remain
ON.
NOTE
The LINE must be installed
for the unit to pass the self-
test and show proper
indication of LED ON.
