More Information

Overview Manuals Port Layout Ring Recovery Network Setup Diagnostics

Features:

  • Two gigabit single-mode SC interfaces connect the switch to optical segments.
  • The RJ45 side has one gigabit port and seven Fast Ethernet ports.
  • Managed ring and diagnostic functions help organize and monitor industrial traffic.
By linking optical and copper equipment, the 6GK5308-2FM00-2AA3 forms one managed Ethernet device without treating all copper ports as the same speed class.

The redundant-ring manager and RSTP functions address topology recovery, while VLAN and IGMP features organize traffic within the configured network.

A separate fault contact, LED indication and C-PLUG give the installed switch distinct signaling, local observation and removable configuration paths.

The Siemens 6GK5308-2FM00-2AA3 SCALANCE X308-2LD Managed Industrial Ethernet Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Copper and fiber connection roles

  • Fiber pair: Two SC connections carry gigabit traffic on single-mode optical fiber.
  • Gigabit copper: One RJ45 port accepts 10/100/1000 Mbit/s equipment.
  • Fast Ethernet: Seven further RJ45 ports accept 10/100 Mbit/s equipment.
  • Link selection: The connected cable and peer interface determine whether a given copper link runs at 10, 100 or 1000 Mbit/s where supported.

Topology and recovery functions

  • Ring manager: The integrated manager coordinates supported redundant-ring operation.
  • RSTP: Rapid Spanning Tree provides another loop-control mechanism for configured topologies.
  • MRP: Media Redundancy Protocol is supported for a configured ring.
  • Standby: Standby redundancy can couple supported network segments without making the switch a substitute for every topology design.

Management and configuration paths

  • Web interface: Device settings can be viewed or changed through web-based management.
  • CLI: A command-line interface provides another management path.
  • VLAN: Port-based and dynamic VLAN functions separate configured traffic groups.
  • C-PLUG: The supplied removable plug carries configuration data independently of the fixed housing.

Local and remote fault indications

  • LEDs: Front indicators identify link and device states locally.
  • Signal contact: The separate two-pole contact provides a wired fault indication.
  • PROFINET diagnosis: A configured PROFINET IO system can receive supported device diagnostics.
  • Port statistics: Error and packet counters help narrow an issue to a specific connection.
Description
In the SCALANCE X-300 family, Siemens 6GK5308-2FM00-2AA3 is an X308-2LD managed industrial Ethernet switch. It passes network traffic between two single-mode optical links and its copper Ethernet ports within an industrial communications segment.

The two SC fiber interfaces of 6GK5308-2FM00-2AA3 carry gigabit optical links, while one RJ45 connection also supports gigabit copper. The other seven RJ45 ports are Fast Ethernet, so equipment connected to them does not gain gigabit speed merely because the switch has a gigabit uplink.

For a managed network, 6GK5308-2FM00-2AA3 can act as a ring redundancy manager and provides RSTP, VLAN, and IGMP functions. Its PROFINET IO diagnosis and port statistics help distinguish a connection fault from an application-level communication problem.

Power for 6GK5308-2FM00-2AA3 enters through a four-pole terminal block, separate from the two-pole signaling contact. Status LEDs and that contact report device faults, while the included C-PLUG retains removable configuration data for the managed switch.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Will both fiber ports on 6GK5308-2FM00-2AA3 accept multimode SC cable?
No. The two optical interfaces on Siemens 6GK5308-2FM00-2AA3 are specified for single-mode SC fiber; the supported distance depends on the fiber link and reaches up to 10 km.
Which RJ45 connection on 6GK5308-2FM00-2AA3 supports gigabit Ethernet?
Only one copper port on 6GK5308-2FM00-2AA3 supports 10/100/1000 Mbit/s; its other seven RJ45 ports are limited to 10/100 Mbit/s.
Can 6GK5308-2FM00-2AA3 manage an Ethernet redundancy ring?
Yes. The 6GK5308-2FM00-2AA3 includes a ring redundancy manager and supports MRP and RSTP; the network topology and selected protocol still need to be configured consistently.
How is a device fault from 6GK5308-2FM00-2AA3 passed to a wired alarm input?
The 6GK5308-2FM00-2AA3 provides a separate two-pole signaling contact for fault indication; it is distinct from the four-pole DC power connector.
What can be checked when one 6GK5308-2FM00-2AA3 port loses traffic?
The 6GK5308-2FM00-2AA3 exposes port diagnostics and error statistics, allowing that connection to be checked before changing ring or VLAN settings elsewhere.
Is a C-PLUG an extra accessory for 6GK5308-2FM00-2AA3?
No. Siemens lists the C-PLUG in the supply scope of 6GK5308-2FM00-2AA3; it is the removable configuration-storage component for this switch.
