What Is the CAB-XPS-58CM=?

The ​​CAB-XPS-58CM=​​ is a specialized power supply cable designed for Cisco’s ​​XPS (Extended Power Supply) modules​​, such as those used in Catalyst 6500 Series switches. Measuring 58 cm (1.9 ft), it connects redundant power supplies to the chassis, ensuring uninterrupted power delivery in mission-critical environments like data centers or financial trading floors.

Key specifications:

• ​​Voltage rating​​: 200–240V AC (dual-phase compatibility).
• ​​Connector type​​: Customized high-current terminals for Cisco XPS systems.
• ​​Compatibility​​: Catalyst 6500-E Series with WS-C650X-SUP modules.

Key Advantages Over Generic Power Cables

Thank you for your feedback

1. ​​Dedicated redundancy support​​: Facilitates ​​hot-swappable power supply failover​​ without downtime, a requirement for Tier IV data centers.
2. ​​High-current capacity​​: Engineered for sustained 30A loads, minimizing voltage sag during peak demand.
3. ​​Shielded design​​: Reduces electromagnetic interference (EMI) in racks with mixed power and fiber-optic cabling.

Addressing Critical User Concerns

​​Q: Can this cable replace third-party power cords in existing XPS setups?​​
A: No—​​CAB-XPS-58CM=​​ uses proprietary connectors and pinouts. Using uncertified cables risks chassis errors or voided warranties.

​​Q: Is it compatible with newer Catalyst 9000 Series switches?​​
A: No—this cable is designed exclusively for legacy Catalyst 6500-E Series. For Catalyst 9500/9300, use ​​CAB-9K-PWR-80CM=​​.

​​Q: Why is the 58cm length critical?​​
A: Optimized for ​​side-to-rear PSU configurations​​ in standard 19” racks, minimizing slack while allowing full rack extension.

Real-World Perspective

In high-stakes environments, ​​power redundancy is non-negotiable​​. While the CAB-XPS-58CM=’s specificity limits its use, its value lies in being the only cable Cisco supports for 6500-E Series XPS failover—a reality that keeps legacy systems alive long after their planned obsolescence. For teams managing aging infrastructure, this cable isn’t optional; it’s a lifeline.
