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.
  • Module 2 ports can be used for stacking or data uplink. Refer to Converting from Stacking to Data Uplink on ICX 7550 Module 2.
  • Module 2 ports can be used for stacking or data uplink. Refer to the "Converting from Stacking to Data Uplink on ICX 7550 Module 2" section of the RUCKUS FastIron Stacking Configuration Guide.
  • 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 ring-topology stack; 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.

  • Module 2 port speeds can be configured on an ICX 7550 standalone (but not on a stack). Refer to Converting from Stacking to Data Uplink on ICX 7550 Module 2.
  • Module 2 port speeds can be configured on an ICX 7550 standalone (but not on a stack). Refer to the "Converting from Stacking to Data Uplink on ICX 7550 Module 2" section of the RUCKUS FastIron Stacking Configuration Guide.
  • A stacking trunk between ICX 7550 devices is only possible in a two-unit configuration (refer to Configuring Two-unit Stack Linear-topology Trunks).
  • A stacking trunk between ICX 7550 devices is only possible in a two-unit configuration (refer to the "Configuring Two-unit Stack Linear-topology Trunks" section of the RUCKUS FastIron Stacking Configuration Guide).
  • 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).
