Extreme ERS Maintenance — vendor-independent service for ERS 3000 to 8000
We service Extreme ERS (Ethernet Routing Switch, Enterasys/Nortel heritage) after factory warranty and Extreme NSA — vendor-independent, with OEM power supplies, fan trays and switches, SLA up to 24×7×4. Complete ERS family: ERS 3500/4800/4900/5900 (edge/aggregation), ERS 8000/8800 (core with modular chassis). Many ERS models have reached Extreme EOSL — TPM is up to 70 percent cheaper than still-available NSA options.
Which ERS models we service
ERS platform history: originally Nortel Networks development, 2009 transferred to Avaya with Nortel acquisition, 2017 transferred to Extreme with Avaya networking takeover. ERS switches are still productive in DACH data centers at former Nortel and Avaya legacy customers — typically in stable installed setups that don't necessarily need refresh. Three classes: ERS 3000/4000/5000 (edge/aggregation, mainly EOSL), ERS 8000 (core chassis, EOSL risk). Many models have reached Extreme EOSL or are approaching.
Why TPM maintenance for Extreme ERS
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.
Generations timeline & TPM coverage

EOSL status of ERS generations
ERS platform is largely EOSL reached — many models were originally developed by Nortel or Avaya and have completed the 7-9 year lifecycle.
