Detailed Description

LINK/ACT LED
(Bi-color LED)

1st LED: Green/Amber

Solid Green = Port linked operating at max port speed, i.e. running 100GbE on QSFP28 port. Green (Luminance at 1.5ft = 45+5 cd/m2)
Flash Green (~30ms) = Port Activity operating at max port speed, i.e. running 100GbE on QSFP28 port. Green (Luminance at 1.5ft = 45+5 cd/m2)
Solid Amber = Port linked operating at lower speed, i.e. running 40GbE or 25GbE or 10GbE on QSFP28 port. Amber (Luminance at 1.5ft = 45+5 cd/m2)
Flashing Amber (~30ms) =Port Activity operating at lower speed, i.e. running 40GbE or 25GbE or 10GbE on QSFP28 port. Amber (Luminance at 1.5ft = 45+5 cd/m2)
Off = No link

Flashing Amber with 1 sec on and 1 sec off – Port Beacon. Amber (Luminance at 1.5ft = 180+10 cd/m2)

All four LEDs shall be used when 4x25GbE mode or 4x10GbE mode is running on QSFP28 port.

Solid Green = 4x25GbE Link on QSFP28 port. Green (Luminance at 1.5ft = 45+5 cd/m2)
Solid Amber = 4x10GbE Link on QSFP28 port. Amber (Luminance at 1.5ft = 45+5 cd/m2)
Flashing (~30ms) Green = 4x25GbE Activity on QSFP28 port. Green (Luminance at 1.5ft = 45+5 cd/m2)
Flashing (~30ms) Amber = 4x10GbE Activity on QSFP28 port. Amber (Luminance at 1.5ft = 45+5cd/m2)
Off = No link

Flashing Amber with 1 sec on and 1 sec off – Port Beacon. Amber (Luminance at 1.5ft = 180+10 cd/m2)
