Hello, welcome HongTelecom
1200 W High-voltage DC Power Module for Huawei CloudEngine (CE) 8800,7800, 6800, and 5800 Series switches

Huawei Data Center Switch includes CloudEngine CE12800, CE12800E, CE1800V, CE5800, CE6800, CE7800, CE8800 Series. In this article, HongTelecom will introduce the 1200 W High-voltage DC Power Module for CE5800, CE6800, CE7800, CE8800 series switches.

1200 W High-voltage DC Power Module

Version Mapping

1200 W high-voltage DC power modules are classified into two types depending on the airflow designs: PHD-1K2WA-B (back-to-front airflow, air exhaust on power module panel) and PHD-1K2WA-F (F: front-to-back airflow, air intake on power module panel).

Table 1 describes the mapping between switch models and 1200 W high-voltage DC power modules.

Function

PHD-1K2WA-B and PHD-1K2WA-F use different airflow designs but have the same functions. Table 2 describes the functions of them.

Table 2 Functions of 1200 W high-voltage DC power modules
Function Description
Input protection Input overvoltage protection and undervoltage protection In either of the two protection states, the power module stops supplying power. When the input voltage restores to the normal range, the power module automatically resumes power supply.
Input overcurrent protection In this protection state, the power module stops supplying power and cannot automatically resume power supply when the input current restores to the normal range.
Output protection Output overvoltage protection In this protection state, the power adapter stops supplying power intermittently. When the output voltage restores to the normal range, the power adapter automatically resumes power supply.
Output overcurrent protection In this protection state, the power module supplies power intermittently. When the output current is limited within a range, the power module automatically resumes power supply.
Output short-circuit protection In this protection state, the power module supplies power intermittently. When the short circuit is removed, the power module automatically resumes power supply.
Overtemperature protection When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.
Heat dissipation
  • PHD-1K2WA-B: back-to-front airflow
  • PHD-1K2WA-F: front-to-back airflow
Hot swap Supported
 NOTE:
When a power module enters overtemperature protection state, take measures to lower its temperature. The power module can automatically resume power supply when the temperature falls within the normal range.

Table 3 describes the indicator on a 1200 W high-voltage DC power module.

Table 3 Indicator description
Indicator Color Description
STAT: power indicator - Off: The power module receives no power input.
Green
  • Steady on: The power module is working normally.
  • Blinking: The power module is in loading or standby state, or the power cable has been connected but the power module is not installed in the switch.
Red

Steady on:

  • Fans of the power module fail.
  • The power module is in overtemperature protection state.
  • The power input is abnormal (input undervoltage or input overvoltage).
  • The power output is abnormal (output overcurrent, output short-circuit, or output overvoltage).
