SCALANCE XR-300 managed
Integration of control cabinets with SCALANCE X-300 in an optical Gigabit ring
The use of media modules in partly and fully modular versions of
the SCALANCE X-300 switches supports:
•
The extension of networks by subsequent insertion of
additional media modules in unused media module slots
•
The changing of cabling technology, e.g. conversion from
copper to fiber-optic cables, or from multimode to single-
mode FOC
■
Design
The SCALANCE XR-300 Industrial Ethernet switches with
rugged metal enclosure with IP30 degree of protection are
optimized for installation in the 19" control cabinet. Versions are
available with 24 V DC or 230 V AC connection. The connection
of the power supply and the data cable outlet are located option-
ally either at the front or rear of the device.
The switches have:
•
4-pin terminal block for redundant voltage feed for protection
against voltage failure in 24 V DC version
•
3-pin terminal block for voltage feed in 230 V AC version
•
2-pin terminal block for connecting the isolated signaling
contact for simple display of faults
•
Row of LEDs for indicating status information (power, link
status, data transfer, power supply, signaling contact)
•
SELECT/SET pushbutton for easy setting of the fault signaling
contact on the device
•
Slot for optional C-PLUG swap medium on the side of the
device for easy replacement in the event of a fault
•
Console port (serial interface) for on-site parameterization/
diagnostics (RJ11 cable to RS232 (9-pin) included in scope of
delivery)
The SCALANCE XR-300 switches are available with the following
port types:
•
12 slots for electrical or optical 2-port media modules for multi-
mode or single-mode connections; the optical media modules
are available in various connection technologies
•
The RJ45 sockets are designed to be industry-compatible
with additional sleeves, for connection of the Industrial
Ethernet FC RJ45 Plug 180
•
All electrical Ethernet interfaces support 10/100/1 000 Mbit/s,
all optical Ethernet interfaces support 100 or 1 000 Mbit/s
•
The SCALANCE XR-300 switches support Gigabit Ethernet (1
000 Mbit/s) at all ports. The 24 ports are divided into three
groups of eight ports each (Gigabit Ethernet Blocking).
Gigabit Ethernet is supported with full wire speed within each
group, but not between the groups.
