Stackable Switch Considerations

Stackable Switch Models

If the Right Switch for the installation is a stacked switch, then one of these switch models would have been chosen:

Switch Model Ports On Max Devices PoE Ports Stacking Bandwidth Max Stack Units
Luxul AMS-4424P Rear 368 368 10Gb 16
Luxul XMS-7048P Front 752 752 10Gb 16
Cisco SG500 Front 392 376 5Gb 8
Cisco SG500X Front 376 376 10Gb 8
Cisco SG550X Front 376 376 10Gb 8

Bandwidth Considerations

When a stacked switch is used, the video bandwidth usage for Transmitters needs to be considered as the stacking cables that connect switches have a maximum bandwidth capability that is much lower than if a single switch is used.

To estimate Just Add Power Transmitter bandwidth usage:

Generation Average Bandwidth* Recommended TX per Gb
2G 125Mbps 8
2GΩ/3G 400Mbps 2.5
3G 500Mbps 2

*Actual bandwidth will depend on source resolution, framerate, colorspace and content.

Stacking Cables

Connecting stacked switches together requires stacking cables.

Most stacking cables are compatible, regardless of the manufacturer.

You can find stacking modules on Luxul's website and stacking modules on Cisco's website or you can use 3rd-party modules.

All Cisco stacking cables that work with the Cisco SG500 are also compatible with the Cisco SG550X.

**Just Add Power has experienced fiber modules passing 5Gb bandwidth between SG500 switches on Cisco firmware and later. However, Cisco's documentation has yet to support this claim.**
