Figure 17. Example of Low-power PoE+ and Non-PoE+ Switches
Invalid
Configurations
Here are examples of invalid configurations. In the first example in Figure
18 on page 34, two low-power, non-PoE+ switches are connected to RPS
1 and 3 System ports on a chassis that has one power module in slot A.
While it is true that you may use one power supply module to supply
system power to two low-power switches, you have to be sure to connect
the switches to the correct ports. The power supply module in slot A
delivers power to RPS 1 and 2 ports. RPS 3 and 4 ports are not receiving
any power because slot B is empty. To correct the problem, you could
connect the AT-x610-24Ts/X Switch to RPS 2 PoE+/System port on the
chassis or install another power supply module.
