Cisco C9200L-48PXG-4X-1E: How Does It Redefin
Core Capabilities and Target Environments T...
Core Technical Specifications and Design
The Cisco C9400-PWR-3200DC= is a 3200-watt DC power supply module designed for the Catalyst 9400 Series modular chassis. It operates on a -48V to -60V DC input and supports N+1 or N+N redundancy for mission-critical deployments. With 94% efficiency, it minimizes energy waste and heat generation, aligning with sustainability goals. This module is compatible with all Catalyst 9400 chassis models, providing consistent power to high-density line cards like the C9400-LC-48TX++= or C9400-LC-12QC=.
Q: Does it support Power over Ethernet (PoE)?
A: No. The C9400-PWR-3200DC= delivers base chassis power only. For PoE, separate PoE modules (e.g., C9400-PWR-6500AC) must be paired with PoE-capable line cards.
Target Use Cases and Deployment Scenarios
Q: Where is DC power preferred over AC in enterprise networks?
A: DC power is critical in environments like telecommunications hubs, industrial facilities, or data centers with DC backup systems, where grid reliability is paramount. The C9400-PWR-3200DC= ensures uninterrupted operation in these settings, leveraging battery-backed DC sources.
Q: How does it handle power redundancy?
A: The module supports hot-swappable replacement, allowing admins to replace faulty units without downtime. Combined with Cisco’s Smart Grid technology, it dynamically adjusts power allocation based on real-time chassis demands.
