  • How many years does the core switch of a network last

    How many years does the core switch of a network last

    On average, a well-maintained network switch can last between 5 and 10 years. However, the exact lifespan depends on factors such as usage, environmental conditions, and the rate of technological advancement. For 2026, there's a new variable that didn't exist five years ago: AI infrastructure is pulling networking refresh cycles forward by 18 to 36 months in environments running GPU. I am currently running multiple HP E5412zl Switches they are about 14 years old. What are some best practices as when to replace these? They work great have had a few modules fail over the years usually its a PoE issue, but HPE/Aruba has been very responsive sending out replacements quickly. However, this isn't a hard-and-fast rule. Several factors can significantly impact its longevity, turning that decade of reliable service into a premature tech graveyard.
