Industrial build for harsh conditions
The IP40 aluminium housing and fanless cooling mean there are no moving parts inside for dust or cold to damage. An operating range of −40 to 75 °C lets you install the switch in an unheated cabinet, a factory hall or an outdoor enclosure. 6 kV lightning protection and two separate power inputs keep the network running even if one power source fails. The SFP slots allow a fibre link to a distant building or mast.
