Power specifications for VSP 4000 switches 4850GTS series and
4450GSX series
The following sections describe the regulatory AC and DC power specifications for the VSP 4000
series switches.
AC power specifications
The following table describes the regulatory AC power specifications for the 4850GTS series and
the 4450GSX-PWR+ switches. The regulatory power specifications are based on the maximum
rated capacity of the power supplies and are not based on typical power consumption, which is
lower.
