Figure 4-28 SCALANCE XR-500
SCALANCE XR500 switches are ideal for use in industrial networks and for integrating the
industrial network in an existing enterprise network. From the control level to the
management level, the switch handles the networking of both plant sections and distributed
field devices and ensures high plant availability with wide-ranging diagnostics options and
high transmission speeds. Due to the scalability of the basic device and optionally available
layer 3 functions, the network can be set up specially for relevant application or adapted and
expanded at any time. SCALANCE XR500 switches are suitable for setting up electrical and
optical Industrial Ethernet linear bus, star or ring structures. With transmission rates up to 10
Gbps, the switches can be used as Industrial Ethernet backbone switches and as hubs in the
plant bus (redundant connection possible).
Apart from four integrated SFP+ slots (for SFP+ transceivers) (10 Gbps) or SFP transceivers
(1000 Mbps) the device variants XR528-6M and XR552-12M provide six or 12 media module
slots. These can be fitted with electrical and/or optical 4-port media modules. Using media
modules or SFP+/SFP allows:
● • Expansion of networks by adding additional media modules in unused media module
slots
● Replacement of the cabling technology, for example converting from copper to FO cable
or from multimode to single mode FO cable
● The transmission rate to be changed, e.g. from 1000 Mbps to 10 Gbps
With their low height of one height unit, the device variants XR524-8C and XR526-8C require
little space in the cabinet. Both devices are suitable for fanless operation and redundant
power supply. Eight of the twenty four ports are designed as combo ports, the can have
pluggable transceivers fitted therefore providing electrical or optical interfaces as required.
