Hardware Lifecycle & Refresh Cycle Guides
Hardware lifecycle is the timing dimension of equipment retirement. When does equipment age out of useful service, why does it get retired, and how is AI changing the equation? The traditional answer was that enterprise networking equipment had 5-to-7-year service lives driven by OEM End-of-Sale timing, depreciation cycles, and slow refresh cadence. The 2026 answer is significantly more compressed, particularly for AI infrastructure where refresh cycles have shrunk to 18-36 months and rack power density has shifted from 5-15 kW to 50-140 kW per rack.
This category collects ROC Telecom’s guides on equipment lifespan, refresh cycle dynamics, and the timing decisions that determine recovery economics. The articles cover the specific lifespans of switches, routers, and optical transport equipment across major OEMs (Cisco, Juniper, Ciena, Infinera, Arista), the OEM lifecycle events that drive value decay (End-of-Sale, Last Day of Support, End-of-Service), and the resale value decay curve that costs operators 5-10% per month after the EOS milestone. Several pieces specifically address how AI is compressing every traditional refresh timeline, why the same equipment generates more retirement volume sooner than five years ago, and how to think about the GPU-versus-server retirement distinction that’s emerging as its own category.
The articles also cover the financial implications of refresh cycle compression. Compressed refresh windows mean more frequent retirement events, larger absolute volumes of retired equipment, and shorter timelines to capture recovery value before it decays. The operational discipline that maximizes capital recovery on the right timing curve looks fundamentally different from the discipline that worked when refresh cycles were measured in years rather than months.
ROC Telecom is an asset recovery and ITAD specialist focused on telecom and data center infrastructure across enterprise, hyperscale, and neocloud operators. The guides in this category reflect direct experience with the lifecycle decisions that determine whether operators capture or lose the recovery value embedded in their retiring infrastructure.
