ES0W2PSD0150

The ES0W2PSD0150 is a specific power module for Huawei network switches. It is not a switch itself, but a component used to provide power to certain switch models.

Here are the key details about the ES0W2PSD0150:

• Type: 150W DC Power Module (Direct Current). The “D” in the product code indicates DC.
• Purpose: It is a hot-swappable, pluggable power supply unit that provides power to compatible Huawei switches, particularly in environments where DC power is the standard (e.g., telecommunications rooms, specific data center designs).
• Compatibility: This power module is designed for use with specific models within the Huawei S5700 series and S6700 series switches. Some of the compatible models include:
  • S5700-28P-LI-BAT
  • S5710-EI series switches (e.g., S5710-28C-EI, S5710-52C-EI)
  • S5720 series switches (e.g., S5720-28X-SI-DC, S5720-52X-SI-DC, S5720-56C-EI-DC)
  • S6720-32C-SI-DC
• Power Output: It provides a maximum output power of 150 W.
• Input Specifications:
  • Rated Input Voltage: -48 V DC to -60 V DC
  • Maximum Input Voltage: -36 V DC to -72 V DC
  • Maximum Input Current: 6 A
• Features:
  • Hot-swappable: This allows the module to be replaced or added without powering down the switch, which is crucial for high availability and network uptime.
  • Redundancy Support: Many of the compatible switches have two power supply slots, allowing for 1+1 power redundancy. By installing two of these modules, the switch can continue to operate even if one power supply fails.
  • Protection Mechanisms: The module includes built-in protections against input undervoltage/overvoltage, output undervoltage/overvoltage, overcurrent, and over-temperature.
• Physical Specifications:
  • Dimensions: 40 mm x 100 mm x 205 mm (H x W x D)
  • Weight: Approximately 0.8 kg

In summary, the ES0W2PSD0150 is a specific 150W DC power module that is a crucial component for ensuring the power and redundancy of various Huawei S-series switches, particularly those deployed in DC-powered environments.
