Stacking (QSFP28) Port LEDs:
Feature | Detailed Description |
LINK/ACT LED (Bi-color LED) | 1st LED: Green/Amber - Â Â 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) - Â Â 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) - Â Â 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) - Â Â 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) - Â Â 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. - Â Â Solid Green = 4x25GbE Link on QSFP28 port. Green (Luminance at 1.5ft = 45+5 cd/m2)
- Â Â Solid Amber = 4x10GbE Link on QSFP28 port. Amber (Luminance at 1.5ft = 45+5 cd/m2)
- Â Â Flashing (~30ms) Green = 4x25GbE Activity on QSFP28 port.
- Â Â Green (Luminance at 1.5ft = 45+5 cd/m2)
- Â Â Flashing (~30ms) Amber = 4x10GbE Activity on QSFP28 port.
- Â Â Amber (Luminance at 1.5ft = 45+5cd/m2)
- Â Â Off = No link
-   Flashing Amber with 1 sec on and 1 sec off – Port Beacon. Amber (Luminance at 1.5ft = 180+10 cd/m2)
