Cisco PWR-C1-715WAC-P-M Full Official Product Description
1. Part Number & Naming Definition
Official Full Name
Cisco Meraki 715-Watt Hot-Swappable 80 PLUS Platinum AC Power Supply Module (Config 1 Meraki Variant)
SKU:PWR-C1-715WAC-P-M
Naming Breakdown
-
PWR: Modular power supply unit
-
C1: Config 1 unified form factor standard for Catalyst / Meraki MS390 switch chassis
-
715W: Maximum rated DC output power of 715 Watts
-
AC: Universal alternating current mains input
-
P: 80 PLUS Platinum high-efficiency certification
-
M: Meraki dedicated commercial variant
Critical Note: Electrically and mechanically pin-compatible with standard PWR-C1-715WAC-P. This -M suffix variant is factory qualified for Meraki MS390 platforms while also working on Catalyst 3850, C9300 series. Distinguish from standard Catalyst PWR-C1-715WAC-P and secondary /2 spare versions.
Core Architecture
The PWR-C1-715WAC-P-M is a hot‑swappable AC‑DC switching power module equipped with integrated temperature-controlled variable-speed cooling fan. It converts universal AC mains input to regulated -56 VDC output to power switch mainboard, internal fan assemblies and medium-to-heavy PoE loads. It supports parallel 1+1 redundant deployment and automatic load sharing inside compatible switch chassis. Embedded protection circuits deliver overvoltage (OVP), overcurrent (OCP), overtemperature (OTP) and short‑circuit auto‑recovery protection.
Deployment Guidance: Calculate the total PoE power budget before deployment. This 715W PSU provides sufficient power for IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) powered endpoints. The 80 PLUS Platinum rating reduces power waste and thermal load compared to standard efficiency power supplies.
Core Product Positioning
The Cisco PWR-C1-715WAC-P-M is a field-replaceable high-efficiency hot‑swappable AC power supply designed primarily for Meraki MS390 access switches, also compatible with Catalyst enterprise access switches requiring medium to heavy PoE power. 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. Optimized for cloud-managed Meraki campus networks and energy-saving enterprise Catalyst switching environments.
