Cisco Industrial Ethernet switch repair and refurbishment.
Component-level diagnostics and repair for Cisco IE series industrial Ethernet switches. Engineer-led, no fix no fee.
Cisco Industrial Ethernet switches
Cisco Industrial Ethernet switches are deployed across UK manufacturing, energy, transportation, and water treatment networks. The discontinued IE-2000 and IE-3000 series remain in widespread service, with replacement requiring migration to the current IE-3200, IE-3300, or IE-3400 platforms at significant cost. We carry out component-level repair on Cisco IE series switches, focusing on power supply faults, expansion module failures, and boot circuit diagnostics — returning the original unit to service without the cost and disruption of a platform migration.
Common faults we fix on Cisco switches
-
Power supply failure — the most common hardware fault across all IE series switches, causing complete failure to power on or intermittent restarts under load
-
Boot faults caused by flash memory failure or power corruption on the boot circuit, preventing the switch from starting up
-
Expansion module port faults on modular IE-3000 and IE-3400 platforms, presenting as dead ports or intermittent link failures on the expansion module
-
Alarm relay output failure preventing the switch from signalling fault conditions to the plant control system

Cisco switch repair FAQs
Do you repair discontinued Cisco IE-2000 and IE-3000 switches?
Yes. The IE-2000 and IE-3000 are discontinued and are among our highest-demand industrial switch repairs. Migration to current-generation IE-3200 or IE-3300 platforms is expensive and disruptive. Our repair service returns the original unit to service at a fraction of the migration cost.
Which Cisco industrial switches do you service?
We service the IE-2000, IE-3000, IE-3400, IE-3400H, and IE-4000 series. Contact us with your specific model and we will confirm scope.
My Cisco IE switch will not boot — is this repairable?
Yes. Boot failures are commonly caused by flash memory chip failure or power corruption on the boot circuit. We diagnose the hardware fault and carry out the component-level repair.
My Cisco IE-3000 expansion module has dead ports — is this repairable?
Yes. We diagnose expansion module faults at board level. Where the fault is component-level rather than a damaged backplane connector, repair is viable.
