Network Equipment Obsolescence: Anticipating and Planning Renewals

Anticipate network equipment obsolescence and renewal through inventory management, a refresh roadmap, budgeting and strategies covering new vs refurbished equipment, TPM and extended support. Critical for NIS2 compliance (no EoL devices). 2026 guide for CIOs.

Key Concepts

• EoS (End-of-Sale): end of new product sales
• EoSM (End-of-Software Maintenance): end of functional patches
• EoVSS: end of security patches
• EoL: complete end of support
• Cisco lifecycle: EoS → EoL = typically 5-7 years

Refresh Roadmap

• Complete inventory (CMDB): serial number + model + purchase date + EoS/EoL
• Alerts 18 months before EoS
• Annual refresh budget: 20-25% of the installed base
• Standard lifecycles: 5-7 years
• Accelerated lifecycle: 3-4 years for the critical core

End-of-Life Strategies

Replacement with new equipment (standard)

• Equivalent or higher-specification hardware
• Phased migration
• SmartNet / FortiCare for support

OPTINOC Refurbished Equipment

• Recent EoS equipment at -40-70%
• 12-36-month warranty
• Ideal for secondary sites and labs
• Less suitable for the critical core

Extended Manufacturer Support

• Cisco Service Extension: +1-3 years after EoL
• 2-3× the standard SmartNet price
• Use case: migration cannot be completed in time

TPM (Third-Party Maintenance)

• Park Place, Curvature, Service Express
• -40-60% vs SmartNet
• No software patches
• Suitable for the post-EoS period until EOL

Risks of EoL Equipment

• No security patches: exploitable vulnerabilities
• Non-compliance with NIS2 / DORA
• No TAC support
• Excluded by IT insurance policies
• Reputational risk: a breach may highlight the use of EoL equipment

Financial Planning

• Standard 5-year depreciation period
• Refresh CAPEX: spread expenditure over several years
• Leasing: an OPEX alternative
• Refurbished equipment to spread CAPEX
