Power Up Gateway
Connect the gateway to a DeviceNet network to power up the gateway.
DeviceNet Status LEDs
The CDN36X gateway has two bi-color status LEDs (
NET
and
MOD
) that indicate operational
status. During power-up, the LEDs cycle through a sequence of alternating red and green. After
power-up, the
NET
LED should be flashing green (or solid green if allocated to a DeviceNet
master) and the
MOD
LED should be solid green. If this does not occur, disconnect from
DeviceNet and verify all the switch settings. See Chapter 8 for additional troubleshooting topics.
