Figure 15. Example of Two PoE+ Switches
In Figure 16 on page 32, two low-power switches are supported by a
single power supply module, in slot A of the chassis. One switch supports
PoE+ while the other does not. (Remember, the terms low- and high-
power do not refer to the PoE+ feature. A switch that supports the PoE+
feature may be a low- or high-power device.) Because it is a non-PoE+
switch, the AT-x610-24Ts Switch is connected to RPS 1 System port, from
which it receives system power for its switching functions. In contrast, the
AT-x610-24Ts/X-POE+ Switch is connected to the RPS 2 System/PoE+ to
receive redundant system power and active PoE+ power.
