1. Part Number & Naming Definition
Official Full Name
Cisco 715-Watt Hot-Swappable Standard Efficiency AC Power Supply Module (Config 1 Form Factor)
SKU:PWR-C1-715WAC
Naming Breakdown
-
PWR: Modular power supply unit
-
C1: Config 1 unified form factor standard for Catalyst 3850 / Catalyst 9300 switch chassis
-
715W: Maximum rated DC output power of 715 Watts
-

Critical Distinction: Mechanically and pin-compatible with PWR-C1-715WAC-P. This unit isstandard efficiency, while the “-P” suffix model delivers 80 PLUS Platinum high efficiency for energy conservation.
Core Architecture
The PWR-C1-715WAC is a hot‑swappable AC‑DC switching power module equipped with integrated variable‑speed cooling fan. It converts universal AC mains input to regulated -56 VDC output to power switch mainboard, internal fan assemblies and substantial PoE loads. It supports parallel 1+1 redundant deployment and automatic load sharing inside compatible switch chassis. Embedded protection circuits implement overvoltage (OVP), overcurrent (OCP), overtemperature (OTP) and short‑circuit auto‑recovery protection.
Deployment Guidance: This 715W power module provides ample power budget for switches populated with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) endpoints including IP phones, wireless access points and IP surveillance cameras.
Core Product Positioning
The Cisco PWR-C1-715WAC is a field-replaceable hot‑swappable AC power supply designed for Catalyst enterprise access switches with medium to heavy PoE power requirements. Suitable as primary or redundant power source for PoE-enabled switch deployments. Dual PSU installation eliminates single point of failure and enables live power module replacement without switch shutdown. Widely deployed in enterprise campus access networks, medium-density PoE LAN environments and branch office switching infrastructures based on Catalyst 3850 and Catalyst 9300 fixed-form-factor switches.
