Powering Up the Island

1

Energize the bus coupler with 24 Vdc. The island will enter a pre-operational stage once it has completed booting.

2

Check the visual indicators on the bus coupler. See TPRBCEIP – Bus Coupler LEDs

• The PWR LED on the bus coupler, which indicates power supply and system status, should be steady green.

• TPRBCEIP — The MS LED, which indicates bus coupler status, should be flashing green, indicating that the island has not yet been configured.

• TPRBCPFN — The BF LED, which indicates an inoperative bus coupler system, should be red, indicating that the island has not yet been configured.

• TPRBCPFB — The COM LED, which indicates bus coupler status, should be flashing red acyclic (two quick flashes per second), indicating that the island has not yet been configured.
