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 specialized stacking cables. Most stacking cables are compatible, regardless of the manufacturer.

**Just Add Power has experienced fiber modules passing 5Gb bandwidth between SG500 switches on Cisco firmware 1.3.7.18 and later. However, Cisco's documentation has yet to support this claim.**
