ICX 7550 Stacking Configuration Notes

Consider the following points when configuring an ICX 7550 stack:

  • Any ICX 7550 models can be linked to form a stack from Module 2.
  • Stacking cannot be enabled on an ICX 7550 device containing configuration for Module 2, including port speed. The configuration must be removed before stacking is enabled.
  • ICX 7550-24, ICX 7550-24P, ICX 7550-48, and ICX 7550-48P devices support only 40-Gbps stacking.
  • ICX 7550-24F, ICX 7550-48F, ICX 7550-24ZP, ICX 7550-48ZP, and ICX 7550-24XZP devices support both 40-Gbps and 100-Gbps stacking.
  • ICX 7550-24F, ICX 7550-48F, ICX 7550-24ZP, and ICX 7550-48ZP models can support a 100-Gbps port in one direction and a 40-Gbps port in the other direction in a stacking ring topology; however, this configuration is not recommended.

  • ICX 7550 stacking links can have a speed of 40 Gbps or 100 Gbps, depending on the model and the installed optics.

    Stacking port speed is not manually configurable for ICX 7550 devices and is automatically determined by the optics installed on the device.

    ICX 7550 100G stacking is supported only on passive cables.

  • If Module 3 has a 2 X 40-Gbps module installed, the user will be unable to configure Module 2 for data uplink.
  • When 100G stacking is operational, LEDs 1 and 3 (for ports 1/2/1 and 1/2/2) glow (solid green).
