Figure 6. Removable and Non-removable Power Supply Modules in x610
Switches
To summarize, a non-PoE+ x610 Series switch uses the AT-RPS3000
Chassis as its active source of system power and its internal, non-
removable module as a redundant source. For a PoE+ x610 Series switch
the reverse is true because its primary source of system power is its
removable internal module and the redundant source is the power module
in the AT-RPS3000 Chassis.

removable module as a redundant source. For a PoE+ x610 Series switch
the reverse is true because its primary source of system power is its

System power for PoE+ and non-PoE+ x610 Series switches is provided
by all four RPS ports on the AT-RPS3000 Chassis. RPS 1 and 3 System
ports provide only system power, and RPS 2 and 4 PoE+/System ports
provide PoE+ power in addition to system power.

ports provide only system power, and RPS 2 and 4 PoE+/System ports
provide PoE+ power in addition to system power.
You may use any of the available power supply modules, listed in Table 1
on page 19, to provide system power to the x610 Series switches. In fact,
the modules, when installed in the AT-RPS3000 Chassis, can provide
system power to two low-power switches at the same time, as explained in
“Low-power and High-power Switches” on page 24.

The switch and chassis do not display the active or redundant status of a
power supply module. You may use the LEDs and switch’s management
software to determine whether a power module is operating correctly, but
not whether it is the active or redundant system power for the switch.

PoE+ Power
The four x610 Series switches that support PoE+ on the twisted pair ports
do not come with power supply modules. The modules have to be
purchased separately. You may use any of the three modules in a PoE+
switch, although the AC AT-PWR250 Module does not provide PoE+
power, only system power. The AT-PWR800 and AT-PWR1200 Power
Supply Modules provide 480 and 780 watts, respectively, of PoE+ power,
in addition to system power.

As explained earlier in this Overview, there is no load sharing of system
power between the power supplies in the switch and AT-RPS3000
Chassis. Only one source is active while the other is held in a redundant
state.
