More Information

Overview Manuals Media Power Fault Mounting

Features:

  • One RJ45 port converts 10/100 Mbit/s copper Ethernet to 100 Mbit/s single-mode fiber.
  • The BFOC optical interface supports the documented single-mode path up to 26 km.
  • Redundant 24 V DC inputs, LED diagnostics, and a signaling contact support monitored operation.
Siemens 6GK5101-1BC00-2AA3 bridges a copper Industrial Ethernet segment and a long-distance single-mode optical segment without managed-switch configuration.

The RJ45 and BFOC ports serve different media, while the converter maintains the 100 Mbit/s optical path between the connected network sections.

Power and alarm wiring terminate separately, allowing redundant 24 V DC feeds and the external fault contact to be checked without disturbing the fiber connection.

The Siemens 6GK5101-1BC00-2AA3 SCALANCE X101-1LD Unmanaged Media Converter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6GK5101-1BC00-2AA3 SCALANCE X101-1LD Unmanaged Media Converter Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

How the two media paths connect

  • Copper side: One RJ45 interface connects a 10 or 100 Mbit/s Ethernet device or network segment.
  • Optical side: One BFOC interface carries the converted link over 100 Mbit/s single-mode fiber.
  • Distance: The documented single-mode optical path extends to 26 km when the specified fiber link conditions are met.
  • Media check: Connector type, fiber mode, and the speed of both connected Ethernet devices must be checked together.

Supply path and terminal organization

  • Input range: The converter accepts 24 V DC through its documented 18 to 32 V DC operating range.
  • Dual feed: The four-pole terminal provides separate entries for the redundant supply arrangement.
  • Power demand: Maximum current consumption is 0.12 A and power loss at 24 V DC is 3 W.
  • Supply review: Verify both feeds, polarity, protection, and common reference before evaluating link diagnostics.

Local and remote status paths

  • Local indication: Front LEDs provide the converter's visible diagnostic status at the cabinet.
  • Remote contact: A separate two-pole terminal block connects the external fault-signaling contact.
  • Set control: The set pushbutton belongs to the documented fault-signaling function and should be handled according to the installed alarm logic.
  • Troubleshooting order: Check power, copper link, fiber path, LEDs, and contact wiring as separate parts of one converter fault.

Cabinet placement limits

  • Rail options: The compact housing can mount on a 35 mm DIN rail or an S7-300 rail.
  • Wall option: Wall mounting is also documented when the fixing and enclosure arrangement are suitable.
  • Enclosure boundary: IP30 protection requires the installation environment to prevent exposure beyond the converter's enclosure rating.
  • Operating climate: The installed unit must remain within -10 °C to 60 °C and 95% relative humidity at 25 °C without condensation.
Description
Siemens 6GK5101-1BC00-2AA3 is a SCALANCE X101-1LD unmanaged industrial Ethernet media converter. One 10/100 Mbit/s RJ45 port receives copper Ethernet traffic and the 100 Mbit/s single-mode BFOC interface transfers that traffic across the optical link.

A 24 V DC source enters 6GK5101-1BC00-2AA3 through the four-pole terminal block, which provides the documented redundant supply connection. The separate two-pole signaling contact passes the configured fault indication to external monitoring while front LEDs provide local diagnostic status.

The single-mode optical path on 6GK5101-1BC00-2AA3 is specified for distances up to 26 km. Because the copper side can negotiate 10 or 100 Mbit/s while the fiber side operates at 100 Mbit/s, both connected Ethernet devices and the fiber plant must be checked as one link.

Installation options for 6GK5101-1BC00-2AA3 include 35 mm DIN rail, wall, or S7-300 rail mounting. Its IP30 enclosure and documented temperature and humidity limits apply to the installed converter and therefore define the cabinet environment.

Technical notes
On Siemens 6GK5101-1BC00-2AA3, the RJ45 side supports 10/100 Mbit/s while the single-mode BFOC side runs at 100 Mbit/s; verify both media and the redundant 24 V DC wiring.

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.
Can multimode BFOC fiber be used on 6GK5101-1BC00-2AA3?
6GK5101-1BC00-2AA3 is the X101-1LD single-mode variant; verify a single-mode BFOC path rather than assuming the multimode X101-1 interface is equivalent.
Why can the copper link on 6GK5101-1BC00-2AA3 be active while the optical path remains down?
For 6GK5101-1BC00-2AA3, separately check the single-mode fiber type, BFOC connections, optical path, 100 Mbit/s peer, and the converter LEDs.
Does 6GK5101-1BC00-2AA3 support a Gigabit Ethernet device?
6GK5101-1BC00-2AA3 provides 10/100 Mbit/s RJ45 and 100 Mbit/s optical interfaces; it does not document a 1000 Mbit/s port.
What should be checked when the fault contact on 6GK5101-1BC00-2AA3 changes state?
On 6GK5101-1BC00-2AA3, review both 24 V DC feeds, RJ45 status, the single-mode optical link, LED indications, and the two-pole contact wiring.
Can 6GK5101-1BC00-2AA3 be powered from only one supply feed?
6GK5101-1BC00-2AA3 provides a redundant four-pole supply connection; verify the installed wiring and alarm behavior for the site's single-feed or dual-feed arrangement before service.
Which mounting record is needed before replacing 6GK5101-1BC00-2AA3?
Record whether 6GK5101-1BC00-2AA3 uses 35 mm DIN rail, S7-300 rail, or wall mounting, along with fiber routing, BFOC orientation, supply terminals, and alarm-contact wiring.
Why is the IP30 rating important for 6GK5101-1BC00-2AA3 placement?
IP30 on 6GK5101-1BC00-2AA3 does not provide a sealed outdoor enclosure, so the cabinet must maintain the documented temperature, humidity, and contamination limits.
