Brocade 6510 Operation
Powering the Brocade 6510 on and off
Complete the following steps to power the Brocade 6510 on.
1. Connect one or both power cords to the power connectors on the power supplies and to a power
source
2. Set the AC power switches to “I”.
Power is supplied to the switch as soon as the first power supply is connected and powered on.
The switch runs POST by default each time it is powered on; it can take up to several minutes to boot
and complete POST.
To power the Brocade 6510 off, power off both power supplies by setting each AC power switch to
“O”. All devices are returned to their initial state the next time the switch is powered on.
LED activity interpretation
System activity and status can be determined through the activity of the LEDs on the switch.
There are three possible LED states: no light, a steady light, and a flashing light. Flashing lights may be
slow, fast, or flickering. The lights are green or amber.
Sometimes, the LEDs flash either of the colors during boot, POST, or other diagnostic tests. This is
normal; it does not indicate a problem unless the LEDs do not indicate a healthy state after all boot
processes and diagnostic tests are complete.
