Siemens SCALANCE industrial switch repair and refurbishment.
Board-level diagnostics and component-level repair for Siemens SCALANCE managed industrial Ethernet switches. No fix no fee.
Siemens SCALANCE switches
Siemens SCALANCE switches form the backbone of industrial Ethernet networks across UK manufacturing, process automation, and infrastructure. From compact managed X-200 units at machine level through to modular X-400 and X-500 Layer 3 switches in the plant backbone, SCALANCE is deeply embedded in PROFINET-based automation architectures. We carry out component-level repair on managed SCALANCE switches where the replacement cost and lead time make repair the practical option — particularly on X-200, X-300, X-400, and X-500 series units that sit at the core of the plant network.
Common faults we fix on Siemens switches
-
Power supply electrolytic capacitor degradation causing intermittent boot failures, spontaneous restarts, or complete failure to power on
-
Individual Ethernet port failure from ESD damage or PHY chip faults, presenting as a dead port with no link LED activity
-
SFP module slot failure on fiber-equipped models preventing uplink connectivity to the plant backbone
-
Boot faults after power events — caused by flash memory failure or power corruption on the boot circuit

Siemens switch repair FAQs
Which Siemens SCALANCE switches do you repair?
We service the managed SCALANCE range including X-200, XF-200, X-300, XR-300, X-400, X-500, and XR-500 series. We also assess discontinued models such as the XM-400. Contact us with your specific order number and we will confirm scope.
My SCALANCE switch has a dead port — is it repairable?
Yes. A single dead port is typically caused by ESD damage to the Ethernet PHY chip on that port. We diagnose at board level and carry out the component replacement where parts are available.
Can you repair the power supply section of a SCALANCE switch?
Yes. Power supply faults are the most common failure across the SCALANCE range. We carry out capacitor replacement and voltage regulator repair at board level.
