Cisco ASR 900 550W AC Power Supply | Spare, Enterprise — A900-PWR550-A=

Keep ASR 900 service plans intact with a Cisco 550 W AC power supply built as a spare for production environments. When power hardware fails, the fastest recovery path is a compatible replacement that fits the platform without guesswork. This unit is intended to restore power capacity quickly, helping reduce downtime risk in edge and aggregation deployments where router availability directly affects connected sites. For teams managing critical network infrastructure, a spare power supply is not a commodity accessory. It is part of the continuity strategy. A platform-matched 550 W AC supply supports predictable replacement planning, simplifies inventory decisions, and helps avoid the delays that come with cross-platform substitutions. That matters when the cost of a failed power module is measured in service interruptions, not just hardware expense. Choose this Cisco spare when you need a direct-fit AC power option for ASR 900 systems and want to keep maintenance aligned with the original platform design. It is a practical way to preserve uptime, reduce recovery time, and maintain confidence in the power path behind your routing infrastructure.
