Cisco PWR-C1-1100WAC-P Full Official Product Description

1. Part Number & Naming Definition

Official Full Name

Naming Breakdown

• PWR: Modular power supply unit
• C1: Config 1 unified form factor designed for Catalyst 3850 / Catalyst 9300 fixed switch chassis
• 1100W: Maximum rated DC output power of 1100 Watts
• AC: Alternating current mains input
• P: 80 PLUS Platinum high-efficiency certification

Critical Note: Platinum certified for optimized power efficiency. Distinguish from standard-efficiencyPWR-C1-1100WACand secondary spare variantPWR-C1-1100WAC-P/2. AC and DC power supplies cannot be mixed within one switch chassis.

2. Core Architecture

Deployment Guidance: This high-capacity PSU provides sufficient power budget for large volumes of IEEE 802.3af (PoE), IEEE 802.3at (PoE+) and UPOE powered endpoints, including Wi-Fi 6/6E wireless access points, multi-line IP phones and high-power IP surveillance cameras. The 80 PLUS Platinum rating reduces power consumption and heat generation to lower ongoing operational costs.
