350 W DC Power Module (PDC350S12)
Version Mapping
350 W DC Power Modules are classified into two types depending on the airflow designs: PDC350S12-CB (back-to-front airflow, air exhaust on power module panel) and PDC350S12-CF (F: front-to-back airflow, air intake on power module panel).
Table 3-17 describes the mapping between switch models and 350 W DC Power Modules.
Appearance
Figure 3-13 shows the appearance of a PDC350S12-CB power module, and Figure 3-14 shows the appearance of a PDC350S12-CF power module.
Function
PDC350S12-CB and PDC350S12-CF power modules use different airflow designs but have the same functions. Table 3-18 describes the functions of them.
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. |

|
Hot swap |
Supported |
|
When a power module enters overtemperature protection state, take measures to lower the ambient temperature. The power module can automatically resume power supply when the temperature falls within the normal range.

Color |
Status |
Description |
|---|---|---|---|
STATUS: power indicator |
Green |
Off |
The power input is abnormal (for example, no input, overvoltage, or undervoltage) or the power output is abnormal (for example, overvoltage, overcurrent, short-circuit, or overtemperature). |
Steady on |
The power module is working normally. |
