Moxa EDS-405A and EDS-408A repair and refurbishment.
Power supply repair, Turbo Ring diagnostics, and board-level repair for Moxa EDS-405A and EDS-408A managed switches. No fix no fee.
EDS-405A / EDS-408A repair and refurbishment
The Moxa EDS-405A and EDS-408A are 5-port and 8-port managed industrial Ethernet switches widely deployed in UK automation networks. The EDS-408A-EIP variant includes explicit EtherNet/IP CIP object support, making it a common choice in Rockwell Automation environments. These switches support Moxa's Turbo Ring and Turbo Chain redundancy protocols for high-availability network configurations. We carry out component-level repair on both models.
Common EDS-405A / EDS-408A faults we fix
-
Power supply capacitor degradation causing intermittent boot failures or spontaneous restarts during operation
-
Turbo Ring redundancy protocol hardware failure preventing the switch from participating in the ring topology
-
Fiber SFP port failure on models equipped with fiber uplinks, preventing backbone connectivity
-
Relay output contact wear preventing the switch from signalling fault conditions via the alarm relay

EDS-405A / EDS-408A repair FAQs
Do you repair the EDS-408A-EIP variant?
Yes. The EDS-408A-EIP includes EtherNet/IP CIP object support for Rockwell integration. We carry out the same board-level diagnostics and repair as on the standard EDS-408A.
My EDS-408A restarts randomly — what is the cause?
Random restarts are typically caused by power supply capacitor degradation. This is a board-level repair involving capacitor replacement, which we carry out routinely.
Can you repair a Turbo Ring fault on a Moxa switch?
We diagnose Turbo Ring faults at board level. Where the fault is a component-level issue in the redundancy circuitry, repair is viable. We assess each unit and confirm viability before proceeding.
