PAC1000D5412

The PAC1000D5412 is a specific power module for Huawei network switches. It is not a switch model itself but a crucial component that provides both system power and Power over Ethernet (PoE) functionality.

Here are the key details about the PAC1000D5412:

• Type: 1000W AC PoE Power Module. It operates on Alternating Current (AC) power and is capable of supplying a significant amount of power over Ethernet cables.
• Function: It serves two main purposes:
  1. System Power: Provides the necessary power for the switch’s internal components.
  2. PoE Power: This is a key feature, as it can supply power to connected devices (such as IP phones, wireless access points, and surveillance cameras) over the Ethernet cable. It supports both PoE (802.3af) and PoE+ (802.3at) standards.
• Power Output: The module has a total maximum output power of 1000 W. Of this, a large portion (up to 754.6 W) is dedicated to PoE.
• Compatibility: This power module is compatible with a wide range of Huawei switches, particularly those in the S5700 and S6700 series that require high power and PoE support. Some specific compatible models include:
  • S5720-32C-PWH-SI-AC
  • S5720-56C-PWH-EI-AC
  • S6720-32C-PWH-SI-AC
  • S6720-52X-PWH-SI
  • S6720-56C-PWH-SI-AC
  • S5730 series switches that support PoE.
• Input Specifications:
  • Rated Input Voltage: 100 V AC to 130 V AC and 200 V AC to 240 V AC, 50/60 Hz. It also has a DC input range of 240 V DC.
  • 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 PAC1000D5412 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 overvoltage and undervoltage, output overvoltage, overcurrent, and short-circuit, and over-temperature to safeguard the switch and connected devices.

In summary, the PAC1000D5412 is a powerful 1000W AC PoE power module from Huawei that is a crucial component for powering high-end switches and supplying robust PoE functionality to a wide range of devices in demanding network environments.
