Media modules for modular SCALANCE X-300 managed
2
■
Overview
•
2-port media modules for flexible, 2-port-granular equipping
of partly and fully modular versions of
SCALANCE X-300 switches (e.g. SCALANCE X308-2M,
SCALANCE XR324-12M) as well as the SCALANCE S627-2M
•
Electrical versions with RJ45 ports are available as well as
optical versions with BFOC and SC ports for the use of
multimode and singlemode fiber-optic cables
•
A 2-port SFP media module permits the optional use of fiber-
optic SFP plug-in transceivers (

with LC connection technology. Versions with coated PCBs
(conformal coating) for railway applications are also available.
■
Benefits
•
Unlimited flexibility in the case of network expansions (e.g.
more terminals) or conversion (e.g. from copper to fiber-optic
cables) due to modular design with media modules
•
Reduction of storage costs and maintenance overhead by
focusing on a few basic device versions
■
Application
The use of media modules in partly and fully modular versions of
the SCALANCE X-300 switches or selected SCALANCE S de-
vices supports:
•
Extension of networks by subsequent insertion of additional
media modules in unused media module slots
•
Changing of the cabling technology (e.g. conversion from
copper to fiber-optic cables, or from multi-mode to single-
mode FOC)
•
Bridging of longer cable runs or use of existing 2-wire cables
(variable distance)
