Core Functionality and Design Purpose

The ​​Cisco C1KTX-1N24P32A-DC=​​ is a ​​32A DC power supply module​​ designed for high-availability chassis systems like the Catalyst 9400 Series. It provides ​​redundant, scalable power​​ for environments where AC grid reliability is insufficient, such as industrial plants, telecom edge sites, or data centers prioritizing DC power efficiency.

Technical Specifications and Key Innovations

Power Delivery and Efficiency

• ​​32A DC output at -48V​​: Delivers ​​1,536W​​ of continuous power to support line cards with high PoE+ demands.
• ​​N+1/N+N redundancy​​: Hot-swappable design ensures zero downtime during module replacement or grid fluctuations.
• ​​94% energy efficiency​​: Meets ​​80 Plus Platinum​​ standards, reducing operational costs in 24/7 deployments.

Environmental Resilience

• ​​Operating temperature range​​: -40°C to 70°C (-40°F to 158°F)
• ​​IP44 rating​​: Protects against dust ingress and water splashes in harsh industrial settings.

Primary Use Cases

Telecom Edge DC Power Plants

Integrates with Catalyst 9400 chassis to power ​​5G RU/DU units​​ and microwave backhaul equipment, leveraging DC’s compatibility with battery backup systems.

Industrial Automation Hubs

Supports ​​Cisco IE3400 Heavy Duty switches​​ in manufacturing sites, where machinery requires uninterrupted PoE+ for sensors and robotic controllers.

Green Data Centers

Aligns with ​​48V DC busway architectures​​, eliminating AC/DC conversion losses for hyperscale operators targeting PUE (Power Usage Effectiveness) below 1.1.

Addressing Critical User Concerns

How does it handle load balancing in redundant configurations?

The module employs ​​adaptive current sharing​​, automatically redistributing loads if a peer unit fails or operates at reduced capacity.

Is it backward-compatible with older Catalyst chassis?

Yes, but firmware updates may be required for chassis models predating ​​Cisco IOS XE 17.6.1​​.

What safety certifications apply?

• ​​UL 60950-1 and EN 60950-1​​ for IT equipment
• ​​ATEX/IECEx Zone 2​​ for explosive atmospheres
