Power Supply Modules
Attention Make sure that one power supply module is always active.
Note The system power requirements are lower than the power supply module capabilities. See the following table.
AC Power Supply
The dual power supplies can supply up to 800-W power across the input voltage range. The load is shared
when both power supply modules are plugged in and running at the same time.
Note The system does not consume more than the capacity of one power supply module, so it will always operate
in full redundancy mode (2130 and 2140 only) when two power supply modules are installed.

DC Power Supply
The power supplies can supply up to 350 W power across the input voltage range. The load is shared when
both power supply modules are plugged in and running at the same time.
