Note
Front-panel PoE ports use Amber to indicate PoE states.
Port LEDs in Default (SYS) Mode
In the default SYS mode, SPD is OFF, and the port status displays behavior for link, traffic, and PoE as
described in the following table:

Port LEDs in SPD Mode

After one press of the Mode button, the port LEDs enter the SPD Display Mode, indicated by the SPD
LED. SPD mode is used to help determine the operational speed of a port.
RJ45 and SFP ports have a single LED per port. QSFP ports have four LEDs because QSFP ports can be
divided into four different channels, each of which can indicate link and activity independent of the
other channels. When a QSFP port is divided, each LED indicates the rate of an individual channel.
When a QSFP port is used as single port, all of the channel LEDs indicate the rate of the single port.
Color and blink pattern indicate speeds, as referenced by the following table:
