Figure 8. Example of a Non-PoE+, Low-power Switch Connected to an
RPS PoE+/System Port
This example illustrates how a power supply module can provide system
power to two low-power switches at the same time. The power supply
module in slot A is actively supporting the low-power AT-x610-24Ts and
AT-x610-24Ts/X Switches, which are connected to the RPS 1 System and
RPS 2 PoE+/System ports, respectively. The power supply module in the
chassis actively delivers system power to both switches, whose own non-
removable internal power supplies operate in redundant states. Again, as
in the previous example, the power module in slot A can be any of the
available models because they are all capable of supporting up to two low-
power switches.
