Figure 5-1. LANVIEW LEDs
PWR (Green)
When this LED is on it indicates that the SEH is receiving power. If this LED is off, it indicates a loss of input power. Check the input power source (circuit breaker, fuse, etc.). If the proper source power is present, the problem could be with the SEH.
MGMT (Green Flashing)
This LED flashes when an intelligent hub manages the SEH. If this LED does not flash, an intelligent hub is not managing the SEH. If you connect an intelligent hub to the SEH and the LED does not flash, inspect the HubSTACK Interconnect cables for proper connections.
