If source A loses power, each switch continues to operate by receiving power
from the attached RPS 2300. When the power to source A returns, the RPS 2300
automatically allows the internal power supplies of these switches powered by
source A to resume receiving power from their own internal power supplies.
If the RPS 2300 has two power supply modules installed, the RPS 2300 can
provide one-to-one support for up to two switches.
An RPS protects network devices against internal power supply failures and AC
circuit failures. An uninterruptable power supply (UPS) protects network devices
against interruption of utility power. For maximum availability, always use the
RPS 2300 with a UPS
