Port LEDs in Default (SYS) Mode

In the default SYS mode, SPD is OFF, and the port status will display behavior for link, traffic, and PoE as

Port LEDs in SPD Mode

After one press of the Mode button, the port LEDs will enter the SPD Display Mode, indicated by the
SPD LED. SPD mode is used to help determine the operational speed of a port.
There are two LEDs per QSFP28 port on 5520 models. In stack mode, the first LED will represent the
link state and traffic of the stack port with solid or blinking green. When a QSFP28 port is used for
Ethernet and partioned to 4x10 or 4x25, one LED will be shared for two ports. The first LED will indicate
state for the first two ports and the second LED will indicate state for the second two ports. The LED is
on or blinking green to indicate link and traffic when any of the 2 ports are up. It is off when both ports
are down. In partitioned 2x50, each LED will represent link and traffic for one 50G port. In aggregate
Meaning
Link is OK; port is not powered
Link is OK; port is powered; no traffic
Link is OK and transmitting packets; port is not powered
Link is OK and transmitting packets; port is powered
No link, or disabled port; port is powered
Port has a power fault
