W2PSA0580

The W2PSA0580 is a specific power module for Huawei network switches. It is not a switch model itself but a crucial component used to provide both system power and Power over Ethernet (PoE) capabilities to a compatible switch.

Here are the key details about the W2PSA0580:

• Type: 580W AC PoE Power Module. It operates on Alternating Current (AC) and is designed to provide PoE power.
• Function: It serves two main purposes:
  1. System Power: Provides power to operate the switch’s internal components.
  2. PoE Power: This module can supply power to connected devices (such as IP phones, wireless access points, or security cameras) over the Ethernet cable. It supports both IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards.
• Power Output: The module has a total maximum output power of 580 W. This is split between system power and PoE power, with a maximum of 369.6 W dedicated to PoE.
• Compatibility: This power module is primarily designed for use with specific models within the Huawei S5700 and S6700 series switches, particularly those with a PoE power architecture. Some confirmed compatible models include:
  • S5710-28C-PWR-EI-AC
  • S5710-52C-PWR-EI-AC
  • S6720-32C-PWH-SI-AC
  • S6720-56C-PWH-SI-AC
• Input Specifications:
  • Rated Input Voltage: 100 V AC to 240 V AC, 50/60 Hz.
  • Maximum Input Voltage: 90 V AC to 290 V AC.
• Key Features:
  • Hot-swappable: This allows the module to be installed or replaced without powering down the switch, which is essential for maintaining network uptime and high availability.
  • Redundancy Support: Many compatible switches have two power supply slots. By installing two W2PSA0580 modules, you can achieve 1+1 power redundancy, ensuring that if one module fails, the second one can take over without interrupting service.
  • Comprehensive Protection: The module includes built-in protection mechanisms against input overcurrent and undervoltage, output overvoltage and overcurrent, short-circuit, and over-temperature to safeguard the switch and connected devices.

In summary, the W2PSA0580 is a specialized 580W AC power module from Huawei that is a key component for powering switches and providing PoE functionality to a wide range of connected devices in compatible S-series models.
