SFP28 port status LED Indications:

One Port Link/ Activity Status Green/Amber bi-color LEDs is provided for each front panel port

Solid Green = Port linked operating at max port speed, i.e. running 25G on SFP28 port

Flash Green (~30ms) = Port Activity operating at max port speed, i.e. running 25G on SFP28 port

Solid Amber = Port linked operating at lower speed, i.e. running 10/1G on SFP28 port.

Flashing Amber (~30ms) =Port Activity operating at lower speed, i.e. running 10/1G on SFP28 port.

Off = No link

Flashing Amber with 1 sec on and 1 sec off – Port Beacon

QSFP28 port status LED Indications:

1st LED: Green/Amber

Solid Green = Port linked operating at max port speed, i.e. running 100G on QSFP28 port

Flashing Green (~30ms) = Port Activity operating at max port speed, i.e. running 100G on QSFP28 port

Solid Amber = Port linked operating at lower speed, i.e. running 40G or 10G on QSFP28 port.

Flashing Amber (~30ms) =Port Activity operating at lower speed, i.e. running 40G or 10G on QSFP28 port.

Off = No link

Flashing Amber with 1 sec on and 1 sec off – Port Beacon

All four LEDs are used when 4x25G mode or 4x10G mode is running on QSFP28 port.

Solid Green = 4x25G Link on QSFP28 port

Solid Amber = 4x10G Link on QSFP28 port

Flashing (~30ms) Green = 4x25G Activity on QSFP28 port

Flashing (~30ms) Amber = 4x10G Activity on QSFP28 port

Off = No link

Flashing Amber with 1 sec on and 1 sec off – Port Beacon
