The diagram below is an example of the connections that may be used for a
building automation system with one MRP ring and two Daisy Chains both supervised by one
network engine
.
Note: When using MRP ring configurations in the network, all engines must be at the same
Metasys release.
The specific termination for a specific installation depends on the switch configuration. In the normal workflow it is summarized in an installation sheet.

| Label | Example use |
|---|---|
| 1 | MRP ring 1, port 1 |
| 2 | MRP ring 1, port 2 |
| 3 | Daisy chain port |
| 4 | DC power input |
| 5 | Maintenance port |
| 6 | Standard location for serial number |
| 7 | SD card slot |
| 8 | Uplink port |
| 9 | Network engine port |
| 10 | Daisy chain port |
The configured ports are set for autonegotiation for speed and duplex.
If a destination port is connected to another active device, then LEDs indicate the port status. For more information, see Table 1.
