page 10.
Powering off the Brocade VDX 6720
To power off the Brocade VDX 6720, power off both power supplies by setting each power supply
switch to “O” for the Brocade VDX 6720-24 or unplugging the power supplies for the Brocade VDX
6720-60.
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: off (no light), a steady light, and a flashing light. Flashing lights
may be slow, fast, or flickering. The LED colors are either green or amber. See Table 3 on page 24
and Table 4 on page 25 for details on LED behavior.
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.
Brocade VDX 6720 LEDs
