Power Supply and Airflow
This article describes the AC power supply and airflow requirements for Cloud Services Gateway (CSG) 620h series appliances.
AC Power Supply
By default, CSG620h series appliances ship with a 36 W external power supply unit (PSU).
Table 1 describes the AC power supply specifications for the PSU.
Table 1: CSG620h AC Power Supply Specifications
| Item | Specification |
|---|---|
| AC input voltage | 100-240 VAC |
| AC input line frequency | 50-60 Hz |
| Power type |
External, AC to 12 V DC power adapter (36 W) |
| DC-to-DC power converter |
An optional DC-to-DC converter for deployments with a DC input voltage exceeding 12 V |
Airflow Requirements
The CSG620h series appliances use a fanless design.
When planning your site for installing a CSG620h series appliance, ensure that adequate clearance is provided around the appliance to allow for natural convection and heat dissipation. Avoid installing the appliance in sealed enclosures without sufficient ventilation.
When placing a CSG620h series appliance on a desktop or mounting it on a DIN rail, ensure that the top cooling fans and side surfaces are not obstructed. Blocking airflow around the chassis can prevent heat from dissipating effectively, which may cause the appliance to overheat and shut down.
