Hirschmann RS40 switch repair and refurbishment.
Board-level diagnostics and component-level repair for Hirschmann RS40 all-Gigabit managed switches. No fix no fee.
RS40 repair and refurbishment
The Hirschmann RS40 is a 9-port all-Gigabit managed industrial Ethernet switch with 5 copper RJ45 ports and 4 SFP combo ports. As the highest-performance compact switch in the Hirschmann OpenRail range, the RS40 is deployed where Gigabit throughput is required across all ports. We carry out board-level repair on RS40 units, focusing on SFP combo port faults, power supply failures, and Ethernet controller issues.
Common RS40 faults we fix
-
SFP combo port failure — with four SFP slots, the RS40 has more fiber interfaces exposed to potential transceiver circuitry faults
-
Power supply capacitor ageing causing intermittent operation or failure to power on
-
Gigabit Ethernet controller failure affecting multiple ports simultaneously
-
Configuration retention failure after internal backup component degradation

RS40 repair FAQs
Can you repair SFP combo port faults on a Hirschmann RS40?
Yes. SFP combo port failure on the RS40 is typically a board-level fault in the transceiver interface circuitry. We diagnose and repair at component level.
My RS40 has multiple dead ports — is it still worth repairing?
Multiple dead ports can indicate an Ethernet controller failure rather than individual port faults. We diagnose the root cause and confirm viability before proceeding.
