III. Power supply system
An S5100-50C-EI switch provides AC power input and RPS DC input. The AC/DC
power inputs can be used at the same time, acting as backup for each other.
Alternatively, you can use either the AC power input alone or the DC power input alone.
Make sure you use an RPS module recommended by H3C as the DC power input.
