Enterprise, Data Centre & Network Security Equipment (2024+)

When Cisco hardware hits its End-of-Sale (EOS) and End-of-Service-Life (EOSL) dates, businesses run into some real problems. This means greater operational risks, higher support costs, and being pushed to replace equipment sooner than they might want.

Flux IT Hardware helps businesses like yours, data centres, and IT service providers manage their network hardware. We make it simple to extend the life of your current equipment or replace old gear, sourcing what you need. We also handle secure decommissioning of retired assets, ensuring a seamless process for any lifecycle event.

Why Cisco EOSL Matters

When Cisco hardware reaches EOSL:

  • ❌ No Cisco TAC support

  • ❌ No security patches or bug fixes

  • ❌ No hardware replacement from Cisco

  • ⚠️ Increased cyber, compliance, and uptime risk

Yet for many organisations, this hardware is still perfectly serviceable.

That’s where Flux IT hardware knowledge comes in.

Red / Amber / Green Lifecycle Risk Scoring

We categorise Cisco hardware by lifecycle risk:

  • 🔴 RED – EOSL reached or within 12 months

  • 🟠 AMBER – EOS announced, limited runway

  • 🟢 GREEN – Supported but approaching EOS

This allows IT teams to prioritise spend, avoid panic refreshes, and plan upgrades on their terms.

Frequently Asked Questions

Q1. Can I keep using Cisco hardware after EOSL?
Right. When something hits EOSL, Cisco walks away – doesn’t mean it breaks. Plenty of companies keep going fine with third-party help instead.
Q2. Is third-party maintenance safe for Cisco equipment?
Absolutely. In companies and server farms, TPM shows up often because it cuts repair bills quite a bit by handling tasks behind the scenes without constant oversight.
Q3. Do you supply refurbished Cisco hardware?
Fresh equipment from Cisco? Flux IT delivers it – checked, ready, backed by flexible warranty choices.
Q4. Can Flux IT help with secure disposal of EOSL equipment?
For sure. Our services include wiping data safely, recycling with certification, plus payouts when possible.
