Power Supply and Airflow
This article describes the AC power supply and airflow requirements for Cloud Services Gateway (CSG) 5000 series appliances.
AC Power Supply
By default, CSG5000 series appliances ship with redundant, hot-swappable AC power supply units (PSUs). These are modularized power supply units that can be removed from the appliance.
Table 1 describes the AC power supply specifications for CSG5000 model appliance PSUs.
Table 1: CSG5000 Model AC Power Supply Specifications
| Item | Specification |
|---|---|
| AC input voltage | 100–240 V |
| AC input line frequency | 50–60 Hz |
| PSU | Internal 850 W, field-replaceable, 1+1 redundant AC input, hot-swappable |
Table 2 describes the AC power supply specifications for CSG5200 and CSG5250 model appliance PSUs.
Table 2: CSG5200 and 5250 Models AC Power Supply Specifications
| Item | Specification |
|---|---|
| AC input voltage | 100–240 V |
| AC input line frequency | 50–60 Hz |
| PSU | Internal 1300 W, field-replaceable, 1+1 redundant AC input, hot-swappable |
Airflow Requirements
The CSG5000 model appliances have 3 field replaceable 2+1 redundancy fans, which are hot-swappable and provide front-to-back cooling.
The CSG5200 and CSG5250 model appliances have 4 field replaceable fans, which are hot-swappable and provide front-to-back cooling.
When planning your site for installing a CSG5000 series appliance in a 19-inch rack, keep in mind that the front side of the rack is the cool area, and the rear side is where hot air exits from the fan. Ensure that there is space on the rear side of the appliance to allow air to exit from the fan.
When placing a CSG5000 series appliance on a desk, ensure that there is space on the rear side of the appliance to allow air to exit from the fan. Also ensure that the vents on the side of the unit are never blocked, to allow hot air to flow out of the appliance. Covering the vents prevents heat from dissipating out of the appliance, which can cause the chassis to overheat and then shut down.
