Nexus 9300 repair and refurbishment
The Cisco Nexus 9300 is the current-generation datacenter switch platform supporting 10G, 25G, 40G, and 100G interfaces. Deployed as leaf and spine switches in UK datacenter fabrics, the Nexus 9300 is a high-value platform where failure directly impacts server and storage connectivity. We carry out component-level repair on Nexus 9300 units, particularly those that have exceeded their warranty period.

Nexus 9300 repair FAQs
Can you repair a Nexus 9300 with power faults?
Yes. Power circuitry faults are the most common failure. We carry out component-level repair on the power circuitry.
My Nexus 9300 has a dead 100G QSFP28 port — is this repairable?
Yes. QSFP28 port failure is typically a transceiver interface or PHY circuitry fault. We diagnose at board level and carry out the repair.
