• Idle consumption: 350W

• ASR1009-X: 420W max (single PSU)

• Idle consumption: 120W
  Note: Neither uses batteries; power metrics reflect AC systems.

6. Compatibility & Expansion

7. Software & Licensing

• ASR-9001: IOS XR (modular OS)

• Licensing: Per-feature tiered ($$$)

• ASR1009-X: IOS XE (unified image)

• Licensing: Essentials/Advantage ($)

8. Price Positioning

• ASR-9001: Starts at $65,000 (base config)

• 5-year TCO: ~$110k with carrier features

• ASR1009-X: $22,500 (fully licensed)

• 5-year TCO: ~$35k with SD-WAN

Decision Scenarios
Choose ASR-9001 when:
✔️ You're a telecom with legacy SONET/SDH gear
✔️ Need 99.999% uptime with ISSU
✔️ Deploying metro Ethernet backbones

ASR1009-X makes sense for:
✔️ Enterprises consolidating firewalls/routers
✔️ Cloud-first SD-WAN transitions
✔️ Remote sites needing zero-touch provisioning

Critical Question: Will you transport broadcast video or cellular backhaul traffic? If yes, the ASR-9001’s timing synchronization is non-negotiable.
