Table 6: Recommended Managed Ethernet Switches Overview For Unigear Digital - ABB UniGear Series Engineering Manual

Managed Ethernet switches
A switch is an Ethernet device that filters and forwards data packets between the LAN seg-
ments. The switches operate on the data link layer and occasionally the network layer.
Packets that arrive on a port are analysed for errors and only forwarded onto the port that
has a connection to the destination device.
The AFS family offers many features which are required in the utility environments, including
fast protection schemes, redundant power supply and alarm contacts, and enables the step-
wise introduction of Smart grid applications. Recommended types of managed Ethernet
switches are shown in table below.
