The ASR-9922-AC’s Role in Cisco’s ASR 9922 Router Ecosystem
The Cisco ASR-9922-AC is a high-output AC power supply module designed exclusively for the ASR 9922 Router, Cisco’s carrier-class platform built for hyperscale IP/MPLS and 5G transport networks. This module delivers reliable, scalable power to support the router’s 22-slot chassis, which handles terabit-level traffic in telecom core and cloud interconnect deployments.
Key technical specifications:
- 4200W output with 94% efficiency (80 Plus Titanium equivalent).
- N+N redundancy for zero downtime during failures or maintenance.
- Universal input voltage (85–305V AC) compatibility across global grids.
- Smart cooling integration with ASR 9922’s airflow system to prevent thermal overload.
Why the ASR-9922-AC Surpasses Legacy Power Modules
A common question: How does this PSU differ from older ASR 9000 Series power supplies like the ASR-9912-AC=?
Critical improvements:
- Power density: 25% higher output in the same 1RU footprint, enabling support for 400G line cards.
- Energy savings: Adaptive voltage scaling reduces idle power consumption by 35% compared to ASR-9912-AC=.
- Predictive analytics: Built-in sensors provide real-time load forecasting via Cisco IOS XR Software.
Deployment Considerations and User Concerns
Question: Can the ASR-9922-AC operate in mixed AC/DC environments?
No. The ASR 9922 chassis mandates uniform power supply types (all AC or all DC) to avoid configuration errors.
Question: What cooling infrastructure is required for optimal performance?
The module supports front-to-back and back-to-front airflow configurations but requires ambient temperatures below 45°C to maintain full 4200W output.
Sourcing and Compatibility Guidance
For guaranteed authenticity and Cisco TAC support, purchase the “ASR-9922-AC” module through itmall.sale. Ensure your ASR 9922 chassis runs IOS XR 7.7.1 or later to leverage advanced power management features.
Field-Tested Perspective
Having overseen ASR 9922 deployments in tier-1 mobile operator networks, I’ve found the ASR-9922-AC’s true value lies in its ability to scale silently under load. In one instance, it maintained voltage stability during a 12-hour grid fluctuation that would have tripped older PSUs—proving its worth in regions with unreliable infrastructure. While its cost may deter budget-conscious teams, its resilience in 400G-era networks makes it non-negotiable for anyone prioritizing uptime over upfront savings.
