​​Technical Profile of the CN129-PUV2-3000WB=​​

The ​​CN129-PUV2-3000WB=​​ is a ​​3000W AC power supply unit​​ designed for Cisco’s high-density chassis systems, including the ​​Cisco Nexus 9500 Series switches​​. It provides redundant, high-efficiency power delivery for data center environments requiring stable and scalable energy distribution.

​​Core Features and Performance​​

• ​​3000W Output​​: Supports ​​240V AC input​​ at 90% efficiency (80 Plus Platinum equivalent), minimizing energy waste.
• ​​Hot-Swappable Design​​: Enables replacement without downtime during operation, critical for ​​24/7 data center uptime​​.
• ​​N+1 Redundancy​​: Compatible with multiple units in parallel configurations to prevent single points of failure.
• ​​Cisco UCS Integration​​: Pre-validated for use with Unified Computing Systems to streamline power management.

​​Ideal Applications​​

This power supply is optimized for:

• ​​Hyperscale data centers​​ deploying high-power switches or blade chassis.
• ​​Financial institutions​​ requiring uninterrupted operation for low-latency trading systems.
• ​​Cloud service providers​​ managing power redundancy across distributed architectures.

​​Addressing Critical User Questions​​

​​Q: Is the CN129-PUV2-3000WB= backward-compatible with older Nexus 9300 chassis?​​
A: Yes, but only in ​​Nexus 9500 Series​​ slots designed for Gen 2 power supplies. Confirm chassis compatibility via Cisco’s Hardware Compatibility Matrix.

​​Q: How does it handle voltage fluctuations?​​
A: Built-in ​​active current sharing​​ and ​​wide input voltage ranges (200–277V AC)​​ ensure stable output during grid instability.

​​Q: What maintenance support is available?​​
A: Cisco offers ​​Smart Net Total Care​​ for proactive monitoring, while [“CN129-PUV2-3000WB=” link to (https://itmall.sale/product-category/cisco/) provides rapid replacement services for mission-critical deployments.

​​Purchasing and Scalability Advice​​

For enterprises prioritizing reliability, purchasing through authorized channels like itmall.sale guarantees ​​Cisco-certified refurbished or new units​​, complete with firmware updates and compliance documentation. Bulk procurement is advisable for large-scale deployments to ensure uniform power supply configurations.

​​Final Assessment​​

The CN129-PUV2-3000WB= is a workhorse for Cisco-centric data centers, though its utility diminishes in hybrid environments using non-Cisco hardware. While newer modular PSUs with higher efficiency margins are emerging, this unit’s ​​proven redundancy​​ and ​​seamless integration​​ with Nexus systems make it a pragmatic choice for risk-averse operators. Its value is clearest in upgrades of existing Cisco infrastructure, where compatibility outweighs the allure of untested alternatives.
