Brocade VDX 6740 Operation

In this chapter

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. Refer to
page 26 and
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 6740 LEDs

The Brocade VDX 6740 switches have the following LEDs:

on page 28 for details on LED behavior.
One bicolor system status LED (green and amber) on the port side.
One power status LED (green) on the port side.
Two Ethernet management port LEDs (green) for the Ethernet management port. The two
LEDs show the status of the port link and the port activity.
One triangle-shaped bicolor port status LED (green and amber) for each 10 GbE port on the
switch. These LEDs are arrayed above each vertical pair of ports on the Brocade VDX 6740.
The left LED corresponds to the upper port of the pair and the right LED corresponds to the
lower port.
One triangle-shaped bicolor port status LED (green and amber) for each 40 GbE port on the
switch. These LEDs are arrayed between each vertical pair of 40 GbE ports on the Brocade
VDX 6740 switches. The left LED corresponds to the upper port of the pair and the right LED
corresponds to the lower port.
One power supply and fan assembly LED (green) above the AC power switch on each combined
power supply and fan assembly on the non-port side of the switch on the Brocade VDX 6740.
