Ethernet network

The multifunction power supply has six Ethernet connection ports with a built‑in Ethernet
switch, supporting RSTP for Class N pathway realization. Follow the procedure below to
connect the device to a network and other system devices.
The network must be set up in such a way that the multifunction power supply can be
discovered and reached by the system controller.

Port 6 is an SFP socket for a Small Form-factor Pluggable module. This allows for a long
distance connection as field wiring between 19"‑racks using glass fiber.

Connect at least one of the ports to the network, so that it can be discovered by the
system controller to make it part of the system.
The other ports can be used for a loop‑through connection to a next device. Devices can
just be daisy‑chained or be connected in a loop, in which case the system can recover
from a broken link.
The availability of a multi‑port switch makes the multifunction power supply an ideal
device for decentralized system clusters that are interconnected to create a large system.
One or more of these multifunction power supplies in cluster can be easily
interconnected to other clusters, while the remaining ports are used to connect loops of
other devices in that cluster.
