If the Right Switch for the installation requires multiple switches, then one of these switch models should chosen:
| Switch Model | Ports On | Max Devices | PoE Ports | Trunk or Stack | Inter-Switch Bandwidth | Max Stack Units |
|---|---|---|---|---|---|---|
| Cisco SG550X | Front | 376 | 376 | Stack | 10Gb | 8 |
JADConfig only supports multi-switch systems in Stack topology.
Please see the Stacking vs Trunking article for more information.
When multiple switches are used, the video bandwidth usage for Transmitters needs to be considered as the cables that connect switches have a maximum bandwidth capability that is much lower than a single switch.
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. The peak bandwidth output of a 3G Transmitter is 850Mbps, most often during boot-up and switching.
Connecting multiple switches together requires specialized cable, and cannot be carried over typical CatX wiring.
Most SFP+ cables are compatible, regardless of the manufacturer.
You can find SFP+ modules on Luxul's website and SFP+ modules on Cisco's website or you can use 3rd-party modules.
All Cisco SFP+ 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 1.3.7.18 and later. However, Cisco's documentation has yet to support this claim.**
The switches listed below are still supported by Just Add Power and JADConfig but are no longer in production by the manufacturer
| Discontinued Model | Maximum Devices | Replacement Model |
|---|---|---|
| Cisco SG500 and SG500X | 47 * 8 | Cisco SG550X |
| Luxul AMS-4424P | 23 * 16 | Cisco SG550X |
| Luxul XMS-7048P | 47 * 16 | Cisco SG550X |
