Power Supply and Airflow
This article describes the AC power supply and airflow requirements for CSG700 appliances.
AC Power Supply
By default, CSG700 series appliances ship with one AC power supply unit.
If you order the CSG700 series appliance with the power over Ethernet (PoE) NIC module, an additional power supply unit ships with the appliance.
Table 1 describes the AC power supply specifications for each power supply unit.
Table 1: CSG700 AC Power Supply Specifications
Item | Specification |
---|---|
AC input voltage | 100–240 Volts |
AC input line frequency | 50–60 Hz |
Typical power consumption with PoE disabled | 35 Watts |
Typical power consumption with PoE enabled | 60 Watts |
Airflow Requirements
The CSG700 series appliance is made of aluminum for optimal heat dissipation.
The appliance has no fans, to minimize noise and to maximize the life of the appliance. Cooling occurs by natural airflow through the vents on the top of the appliance.
When planning your site for installing a CSG700 series appliance in a 19-inch rack, allow a minimum of 0.5 RU space above the appliance to allow hot air to flow out of the appliance. However, itt is recommended that you allow 1 RU space above the appliance for cooling.
When placing a CSG700 series appliance on a desk, ensure that the vents on the top 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 will cause the chassis to overheat and then shut down.
