Figure 6-1 LANVIEW LEDs
PWR
When this green LED is on, it indicates that the SEH is receiving power.
If this LED is off, it indicates a loss of input power. Check that the power
cord is properly plugged into the SEH and into the ac input power source
(circuit breaker, fuse, etc.). If the proper source power is present, the
problem could be with the SEH.
NOTE
Flashing indicates an irregular LED pulse.
Blinking indicates a steady LED pulse.
