• Extender interface for expansion by 8 Fast Ethernet ports (X414‑3E only):
  • Electrical ports with Fast Ethernet extender (can be docked on right of switch) or
  • optical ports with module extender and media modules
• Implementation of optical Gigabit rings with 2‑port Gigabit Ethernet media module for conversion of integral Gigabit Ethernet ports to fiber-optic (FO):
  • Module version for multi-mode (1000BaseSX ports for up to 750 m FOC) and
  • single-mode (1000BaseLX ports for up to 120 km FOC, see Catalog IK PI)
• SCALANCE X414‑3 has 2 slots for optical Fast Ethernet media modules with 2 ports, SCALANCE X408‑2 has 2 universal slots, can be alternatively used for optical Fast Ethernet or Gigabit Ethernet media modules with 2 ports
• Integration in optical 100 Mbit/s rings using plug-in 2‑port Fast Ethernet media module for multi-mode FOC up to 5 km or single-mode FOC up to 70 km
• Optical interfacing of remote nodes via a second plug-in 2‑port FOC media module for Fast Ethernet
• Addition and removal of extenders (only X414‑3) and media modules during operation
• Max. cable lengths between two modules for communication via multi-mode FOC (for cables, see section on passive network components):
  • Up to 3 000 m via 100BaseFX ports (100 Mbit/s)
  • Up to 750 m via 1000BaseSX ports (1 000 Mbit/s)
• Max. cable lengths between two modules for communication via twisted-pair (for cables, see section on passive network components):
  • Up to 100 m via 10/100BaseTX (10/100 Mbit/s) or 1000BaseTX ports (1 000 Mbit/s)
• Detection of failure of a transmission route or a switch in the ring and activation of the substitute route within 0.3 s (also in large networks):
  • With Gigabit Ethernet (SCALANCE X‑400 switches in ring) just like
  • With Fast Ethernet (SCALANCE X‑400 switches in the ring with SCALANCE X‑200 or X‑200 IRT)
• Standby functionality for redundant connection of two rings
• Slot numbering and labeling strips for unambiguous port identification
• The permissible ambient temperature during operation varies depending on the device type:
  • -40 to +70 °C (X414-3E)
  • 0 to +60 °C (X408-2)

Media modules (MM) for SCALANCE X414-3E and SCALANCE X408-2

SCALANCE X-400 switches can be equipped with 2-port media modules. Media modules are available for both multi-mode and single-mode optical fibers. They can be added or replaced during network operation. The operating temperature range is -40 to +70 °C. The SCALANCE X414-3E basic unit supports two optical Gigabit Ethernet ports and up to four additional optical Fast Ethernet ports.

On two media-module slots, SCALANCE X408-2 supports as many as four optical ports which can optionally be equipped with optical Gigabit Ethernet or Fast Ethernet media modules.

The following media modules are available:

• MM491-2;
  two fiber optic ports (BFOC sockets) 100 Mbit/s for distances up to 5 km with multi-mode fiber-optic conductors
• MM491-2LD;
  two fiber optic ports (BFOC sockets) 100 Mbit/s for distances up to 26 km with single-mode fiber-optic conductors
• MM491-2LH+;
  two fiber optic ports (SC sockets) 100 Mbit/s for distances up to 70 km with single-mode fiber-optic conductors
• MM492-2;
  two fiber optic ports (SC sockets) 1 Gbit/s for distances up to 750 m with multi-mode fiber-optic conductors (when using SIMATIC NET FO cable 50/125µm)
• MM492-2LD;
  two fiber optic ports (SC sockets) 1 Gbit/s for distances up to 10 km with single-mode fiber-optic conductors
• MM492-2LH;
  two fiber optic ports (SC sockets) 1 Gbit/s for distances up to 40 km with single-mode fiber-optic conductors
• MM492-2LH+;
  two fiber optic ports (SC sockets) 1 Gbit/s for distances up to 70 km with single-mode fiber-optic conductors
• MM492-2ELH;
  two fiber-optic ports (SC sockets) 1 Gbit/s for distances up to 120 km with single-mode fiber-optic conductors

Plug-in media modules for Gigabit Ethernet convert the Gigabit Ethernet twisted pair-ports included in the switch to optical mode. The Gigabit ports can then be used as either twisted-pair or fiber-optic ports. In the case of the SCALANCE X414-3E basic device, optical media modules for Fast Ethernet each create two additional ports per slot.

Extender modules for SCALANCE X414‑3E

An optional extender module with up to eight additional Fast Ethernet ports can be mounted next to the expansion interface of the SCALANCE X414-3E. The operating temperature range is -40 to +70 °C.

Versions:

• EM495-8 with 8 twisted pair ports (RJ45 sockets with retaining sleeves) 10/100 Mbit/s; this enables the twelve onboard Fast Ethernet twisted pair ports of the SCALANCE X414-3E to be expanded to a total of 20 ports.
• EM496-4 with 4 additional media module slots for Fast Ethernet media modules for up to 8 optical Fast Ethernet ports
