Cisco Catalyst and Nexus switch repair and refurbishment.
Board-level diagnostics and component-level repair for Cisco Catalyst and Nexus enterprise and datacenter switches. No fix no fee.
Cisco Catalyst & Nexus switches
Cisco Catalyst and Nexus switches form the backbone of enterprise campus and datacenter networks across the UK. From access-layer Catalyst 2960 switches in offices to Nexus 9300 spine switches in datacenters, Cisco hardware dominates the UK enterprise networking market. Discontinued models including the Catalyst 2960-X, 3750-X, and 3850 remain in widespread service, with migration to current-generation Catalyst 9000 platforms representing a significant investment. We carry out component-level repair on Cisco enterprise switches — focusing on power circuitry faults, PoE controller failures, port-level repairs, and boot circuit diagnostics.
Common faults we fix on Cisco switches
-
Power circuitry faults causing complete failure to power on or intermittent restarts under load
-
PoE controller degradation reducing available PoE budget or causing individual port PoE failures on access-layer switches
-
Stacking module or cable faults on stackable platforms such as the Catalyst 3750-X, 3850, and 9300, disrupting stack ring connectivity
-
Boot faults caused by flash memory failure or power corruption on the boot circuit

Cisco switch repair FAQs
Which Cisco switches do you repair?
We service the Catalyst 2960-X, 2960-XR, 3750-X, 3750-G, 3850, 9200, 9300, 9500, and the Nexus 3000, 5000, and 9300 series. Contact us with your specific model and we will confirm scope.
Do you repair discontinued Cisco Catalyst switches?
Yes. Discontinued models such as the Catalyst 2960-X, 3750-X, and 3850 are among our highest-demand repairs. Migration to current Catalyst 9000 platforms is expensive and disruptive. Our repair service returns the original unit to service.
My Cisco switch stack has a failed member — can you repair just that unit?
Yes. We repair individual stack members. A failed stack member can be sent to us while the remaining stack continues to operate at reduced capacity.
Do you offer a warranty on repaired Cisco switches?
Yes. All repaired units are returned with a 2-year limited warranty covering the repair carried out.
