Figure 1. Cisco 7600 Series 4500W DC Power Supply

Features and Benefits

• Variable output design configurable for 4500W, 3000W, or 1500W output corresponding to three, two, or one input active

• Equally sized, multiple inputs, which allow lower fusing requirements and maintain consistent wire gauge among 4500W, 3000W, and 1500W output configurations

• Industry-standard dual post terminals

• Terminal design that facilitates cable entry from left or right side

• Pawl type sliding power switch

• Compatible with Cisco 7606-S chassis

• Network Equipment Building Standards (NEBS) Level 3 compliant power supply
