Cisco MA-PWR-250WAC Full English Description

Product Overview

Important Note: This power supplydoes not provide PoE power budget. For PoE-capable Meraki platforms, select dedicated high-wattage PoE PSU variants. Always install identical PSU models when running redundant configurations.

Key Features

1. 250 Watt Continuous Rated Output

   Provides sufficient power for base system operation of compatible Meraki switches and MX security appliances. Supports automatic load sharing when two identical power supplies are installed redundantly.
2. Universal Wide-Range Global AC Input

   Worldwide auto-ranging mains specification:

• Input Voltage: 100 VAC ~ 240 VAC
• Operating Frequency: 50 Hz – 60 Hz
• Built-in standard IEC C14 inlet for AC power cord connection

1. Hot-Pluggable Modular Form Factor

   Horizontal pluggable FRU installed inside Meraki chassis.

   Important Note: Not interchangeable with other Meraki PSU series (MA-PWR-350WAC / MA-PWR-640WAC). Do not mix AC and DC power supplies within one chassis.
2. Hot-Swap Support

   Supports Online Insertion and Removal. Technicians can replace faulty power modules without powering off the host device, enabling non-disruptive maintenance and minimizing service outages.
3. Front Panel LED Status Indicators & Meraki Cloud Monitoring

   Faceplate status LEDs display AC input status (AC OK) and power output health (PS OK). Operational metrics and fault alerts are reported to Meraki Dashboard for centralized cloud monitoring and notifications.
4. Multi-Layer Hardware Protection

   Integrated overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP), surge protection and short-circuit protection to safeguard both the power supply and Meraki host hardware.
5. High Energy Efficiency Design

   Optimized power conversion reduces idle power consumption and thermal output, supporting reliable 24/7 continuous rack operation for branch, campus and data center edge environments.

Supported Hardware Platforms

• Meraki MS Series Switches: MS250, MS320, MS350, MS410, MS425
