W0PSA5000

The W0PSA5000 is a specific power module for Huawei network switches. It is not a switch model itself, but a component used to provide power and, importantly, Power over Ethernet (PoE) capabilities to compatible switches.

Here are the key details about the W0PSA5000:

• Type: 500W AC Power Module. It operates on Alternating Current (AC) power.
• Function: It serves two main purposes:
  1. System Power: Provides the necessary power to operate the switch’s internal components.
  2. PoE Power: A key feature of this module is its ability to supply power to connected devices (like IP phones, wireless access points, or surveillance cameras) over the Ethernet cable. It complies with both IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards.
• Power Output: The module has a total maximum output power of 500 W. This is divided into:
  • System Power: 120 W (+12V output).
  • PoE Power: 380 W (-53.5V output).
• Compatibility: This power module is compatible with a wide range of Huawei switches, particularly models that support PoE and require higher power. It’s often used with the S2700, S3700, S5700, and S6700 series switches. Some specific examples include:
  • S5700-28C-PWR-EI
  • S5700-52C-PWR-EI
  • S6700-24-EI
  • S6700-48-EI
  • S5720-series switches that support PoE.
• Input Specifications:
  • Rated Input Voltage: 100 V AC to 240 V AC, 50/60 Hz.
  • Maximum Input Voltage: 90 V AC to 264 V AC.
• Key Features:
  • Hot-swappable: This allows the module to be installed or replaced without powering down the switch, ensuring no disruption to network services.
  • Redundancy Support: Many compatible switches have dual power supply slots. By installing two W0PSA5000 modules, you can achieve 1+1 power redundancy, where the second module provides a backup in case the first one fails.
  • Comprehensive Protection: The module includes built-in protection mechanisms against input overcurrent and undervoltage, output overvoltage, overcurrent, short-circuit, and over-temperature.

In summary, the W0PSA5000 is a specialized 500W AC power module from Huawei that is essential for powering switches and providing PoE functionality to a wide range of connected devices, especially within the S5700 and S6700 series.
