Alarm Contact
The FL SWITCH SFN… switch provides contacts (R1, R2)
for remote alarms if a failure is detected.
– The contact closes if one or both power supplies fail.
– The contact opens if power is OK.
The maximum current, including inrush, is 100 A.

6.5 Ethernet Interface
The FL SWITCH SFN… has five Ethernet ports on the front
in RJ45 format to which only twisted-pair cables with an
impedance of 100 Ω can be connected. The data
transmission speed is 10/100 Mbps. In addition, every port
has an auto crossing function: it is not necessary to make a
distinction between 1:1 or crossover Ethernet cables.

Fiber Optic Connection
Two different types of fiber optic connection are available.
The fiber optic connector(s) are located on the lower front
face of the 8-port models or on the bottom face of the 5-port
models.
The ST connectors are typically individual round connectors
and use a 1/4-turn connection.
