Cisco PWR-C1-350WAC-P Full Official Product Description
1. Part Number & Naming Definition
Official Full Name
Cisco 350-Watt Hot-Swappable 80 PLUS Platinum AC Power Supply Module (Config 1 Form Factor)
SKU:PWR-C1-350WAC-P
Naming Breakdown
-
PWR: Modular power supply unit
-
C1: Config 1 unified form factor for Catalyst 3850 / Catalyst 9300 switch chassis
-
350W: Maximum rated DC output power of 350 Watts
-
AC: Universal alternating current mains input
-
P: 80 PLUS Platinum high-efficiency rating
Critical Distinction: Mechanically and pin-compatible with standard PWR-C1-350WAC; the primary difference is higher platinum efficiency for energy saving and reduced heat dissipation.
Core Architecture
The PWR-C1-350WAC-P 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 fans and limited PoE loads. It supports parallel 1+1 redundant deployment and load sharing inside supported chassis. Built-in protection circuits implement overvoltage (OVP), overcurrent (OCP), overtemperature (OTP) and short-circuit auto-recovery protection.
Deployment Guidance: For PoE-enabled switches, calculate total available power budget. This 350W PSU delivers limited power capacity for IEEE 802.3af/at powered devices. Platinum efficiency reduces power consumption and thermal output compared to standard-efficiency non-P variants.
Core Product Positioning
The Cisco PWR-C1-350WAC-P is a field-replaceable high-efficiency hot-swappable AC power supply designed for Catalyst enterprise fixed-form access switches. Suitable for primary or redundant power deployment in non-PoE or light PoE-load environments. Dual PSU installation eliminates single point of failure and enables live power module replacement without switch shutdown. Ideal for energy-conscious enterprise campus access, branch office LAN and medium-scale data center top-of-rack switching deployments where power consumption optimization is required.
