1200 W High-Voltage DC Power Module (PHD1K2S12-DB)
Version Mapping
Only the PHD1K2S12-DB (B: back-to-front airflow, air exhaust on power module panel) 1200 W high-voltage DC power module is available.
Table 3-57 describes the mapping between switch models and the 1200 W high-voltage DC power module.

Function
Table 3-58 describes the functions of the PHD1K2S12-DB power module.
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 module stops supplying power intermittently. When the system recovers from output overvoltage, the power module 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. |

Supported |
|
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.

Indicator |
Color |
Status |
Description |
|---|---|---|---|
STAT: running status indicator |
Green |
Steady off |
The power input is abnormal (for example, no input, overvoltage, or undervoltage), or the power module is in overtemperature protection state. |
Steady on |
The power module is working properly. |
||
Blinking |
The system software of the switch is being upgraded or downgraded, or the power output is abnormal (for example, overcurrent, short circuit, or overvoltage). |
