IE-4000 repair and refurbishment
The Cisco IE-4000 is a large-frame managed Layer 2/Layer 3 industrial Ethernet switch platform available in configurations from 8 to 28 ports with support for Gigabit and 10-Gigabit uplinks. Deployed in UK substations, process plant, and large-scale automation environments, the IE-4000 is one of the most capable and most expensive industrial switches available. We carry out component-level repair on IE-4000 units.

IE-4000 repair FAQs
Can you repair a Cisco IE-4000 with a failed power supply?
Yes. Power supply failure is the most common fault on the IE-4000. We carry out component-level repair on the power circuitry.
My IE-4000 has dead ports on an expansion module — is this repairable?
Yes. We diagnose expansion module faults at board level and carry out component-level repair where viable.
