EOSL status of ERS generations

ERS maintenance is the largest cost saving lever in the Extreme portfolio — many ERS models have reached Extreme EOSL, NSA renewals are partially no longer available or priced at premium terms. For DACH legacy customers operating ERS since Nortel or Avaya times, the alternative option is often either an expensive refresh to X-Series/VSP or a premium EOSL NSA renewal. TPM is the economic middle path: existing ERS hardware remains productive, maintenance costs drop to 30-40 percent of NSA level, refresh can be planned decoupled in time and economically.

We service ERS switches with OEM power supplies, fan trays and complete switches as replacement from our own warehouse. For very old ERS components (Nortel heritage from 2008+) we use certified refurbishing partners from the Nortel/Avaya networking ecosystem. ERS OS (Avaya/Nortel-based switch OS) continues to work without licensing — code updates are no longer available for many ERS models anyway (EOSL reached), usually uncritical with stable configs.

The full OEM-vs-TPM matrix (spare parts, SLA tiers, language, sub-outsourcing, compliance docs, reporting) is the same for every Extreme Networks line — see the Extreme Networks battle card.

BAIT/MaRisk documentation package, DORA Art. 28 contract template, ISO 27001 and GDPR-compliant media handling apply identically to every Extreme Networks line — details on the Extreme Networks battle card.

Same four steps for every Extreme Networks line: inventory → fixed-price quote in 48 h → contract (BAIT/MaRisk/DORA hooks) → hand-over with spare-parts provisioning. Details on the Extreme Networks battle card.

Which ERS models do you service?

Complete ERS family: ERS 3500 (edge), ERS 4800/4900 (aggregation), ERS 5900 (aggregation/core), ERS 8000/8800 (core with modular chassis). Including all power supplies, fan trays, line cards for ERS 8000 chassis and optics. Many ERS models have reached Extreme EOSL — we stock components for fleet continuation.

What does TPM cost for ERS compared to Extreme NSA?

30 to 70 percent savings — the largest spread in the Extreme portfolio because ERS EOSL models are extendable at Extreme only at premium terms or no longer at all. For an ERS 4900 with 24×7×4, TechCare is roughly 65% below the Extreme NSA price (if NSA is still available), and roughly 65% for an ERS 8800 core as well. For installed deployments with 30-50 ERS switches, it is roughly 65–70% below the NSA price.

Do ERS OS functions continue to work without an NSA contract?

Yes. ERS OS (the Avaya/Nortel-based switch OS) continues to work on your ERS switches without licensing — all layer 2/3 functions, spanning tree, OSPF, SMLT (Split Multi-Link Trunking), VRF, multicast, IP Shortcut Routing stay functionally active. Code updates to newer ERS OS versions are no longer available for many models anyway — usually uncritical with stable ERS configs.

How long can we economically operate ERS?

From a pure hardware maintenance perspective: 5-10 years of further operation is realistic because components and refurbishing partners remain available. From a strategic perspective: ERS is end-of-life platform, refresh to X-Series or VSP will be required long-term. TPM maintenance is the economic bridge — you keep ERS fleets productive, save 30-70 percent vs. NSA and can decouple refresh strategy in time and budget.

Can you service very old ERS 8000?

Yes, a focus area. ERS 8000/8800 (developed 2008 under Nortel, EOSL from 2018-2022) is still productive in DACH data centers at former Nortel and Avaya legacy customers. We stock line cards, supervisor modules, power supplies and fan trays for ERS 8000 chassis. For very old components we use certified refurbishing partners from the Nortel/Avaya networking ecosystem.

Which SLA levels do you recommend for ERS?

ERS edge in stable installed setups: 5×9 NBD or Parts Only is typically economical — most ERS edge switches are in non-critical office areas. ERS 4900/5900 as aggregation: 5×9 NBD or 24×7×4 depending on workload criticality. ERS 8000/8800 core: 24×7×4 because core outage affects entire data center connectivity. Multi-site with mixed SLA levels is standard.
