Low-power and High-power Switches
The x610 Series switches are grouped into two categories of system
power, which, as explained earlier, refers to the power required to run all
switching and hardware functions, except for PoE+. The switch categories
are low-power and high-power. The basic rule is that switches that have
24 ports are low-power devices while units that have 48 ports are high-
power units. An exception is the 24-port AT-x610-24SPs/X Switch, which
is a high-power device. The table shown here lists the two switch
categories.
The two categories are important because the power supply modules can
support two low-power switches or one high-power switch at the same
time. This table lists the valid and invalid configurations of low- and high-
power switches for the power modules.
Caution
A power supply module that is connected to an invalid configuration
may overload and fail. The responsibility for adhering to the rule
belongs to the installer because the AT-RPS3000 Chassis cannot
determine the low- or high-power status of the switches connected
to its ports.
