Features
The AT-RPS3000 Chassis is a modular power supply system for the x610
Series of Layer 3 Gigabit Ethernet switches. It protects the switches from
power supply failures and provides additional PoE+ power.
The chassis can support two or four x610 Series switches, depending on
the switch model. It has two slots for power supply modules, an LED panel
for viewing the status of the power modules, and four RPS connectors.
As explained in this overview, the power supply modules in the chassis
function in either a redundant or an active state, depending on the switch
model. For non-PoE+ x610 Series switches, the chassis acts as the active
power source for the switches, whose own internal, non-removable power
supplies function as backup modules. For PoE+ switches, the chassis acts
as a redundant power supply for system power and in a load-sharing
mode for PoE+ power.
The AT-RPS3000 Chassis is designed specifically for the x610
Series of Layer 3 Gigabit Ethernet switches and should not be used
with any other product.
The AT-RPS3000 Chassis is not a battery backup unit. The power
supply modules in the chassis have to be connected to active power
sources to deliver power to the switches.
LED PanelThe front panel of the AT-RPS3000 Chassis has an LED panel that
displays status information about the power supply modules and RPS
ports. The LEDs are described in “LEDs” on page 42.

switches come with non-removable power supply modules.
The AT-PWR800 and AT-PWR1200 Modules are compatible with
non-PoE+ x610 Series switches. They may be used in the
AT-RPS3000 Chassis to provide active system power to non-PoE+
switches.
The chassis has slots for two power supply modules. You may install one
or two modules. The power supply modules may be the same model or
different models. There are some combinations of power supply modules,
however, that are not supported. Table 2 lists the valid and invalid
combinations of modules for the chassis.

AT-RPS3000 Redundant Power Supply Installation Guide
System Power and Power for PoE+
Although the product name contains the acronym “RPS,” which stands for
“redundant power supply,” the AT-RPS3000 Chassis actually functions as
the active, primary source of system power for some of the switches in the
x610 Series. For others it functions both as a redundant source of system
power and as an active source of additional PoE+ power.
The easiest way to explain how and when the chassis supplies power to
the x610 Series switch is to divide the discussion into the two types of
power the switch may require:
“System Power,” next
“PoE+ Power” on page 22
System PowerThe switch uses system power to operate its switching, CPU, LEDs, fans,
and management functions. The only function not supported by system
power is PoE+.
The switch may obtain its system power either from its own internal power
supply module or from a module in the AT-RPS3000 Chassis. There is no
load-sharing of system power. Consequently, one of the sources is going
to be actively providing system power to the switch while the other source
is held in a redundant state.
The active source of system power is different for non-PoE+ and PoE+
x610 Series switches. Non-PoE+ switches use the power modules in the
AT-RPS3000 Chassis as their primary, active power source for system
power, and place their internal power modules in a redundant state. Thus,
a non-PoE+ switch relies upon the AT-RPS3000 Chassis to provide all of
its system power, and activates its internal power supply only if it stops
receiving system power from the chassis.
For PoE+ switches, the opposite is true. They use their internal power
supply modules as the active source for system power, and the power
module in the AT-RPS3000 Chassis as the redundant power source.
Should there be a failure of the internal power supply in the switch or an
interrupt in the AC power to it, the switch immediately begins to draw
system power from the AT-RPS3000 Chassis to prevent any interruption
to its network operations.
The easiest way to determine whether the switch is a PoE+ or non-PoE+
x610 Series switch is to examine its model name on the front panel. PoE+
switches have “POE+” in their product names. Another way is to look at
the back panel to see if the power supply is removable or non-removable.
PoE+ switches have removable power modules while non-PoE+ switches
have non-removable modules, as shown in Figure 6.

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, nonremovable 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.
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.
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+ PowerThe 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
22
state.
AT-RPS3000 Redundant Power Supply Installation Guide
PoE+ power is different in that the power supplies in the switch and
chassis do use load-sharing to provide power to the powered devices. This
assumes, of course, that both supplies have PoE+ power. So, in essence,
the AT-RPS3000 Chassis performs two roles for PoE+ switches. It acts as
a redundant source of system power for the switches and, assuming the
chassis has PoE+ power supplies, actively provides them with additional
power for PoE+ so that they can support more powered devices.
Of the three available power supply modules for the chassis, two modules
provide PoE+ power along with system power to the PoE+ switches. They
are the AT-PWR800 and AT-PWR1200 Modules. These modules can
provide PoE+ power to just one switch at a time, meaning that each PoE+
switch has to have a separate power module in the AT-RPS3000 Chassis,
that is, if you want the switches to receive additional PoE+ power from the
chassis.
All four RPS ports on the chassis may be used to provide system power to
the switches. But only RPS 2 and 4 ports, labeled PoE+/System, may be
used to supply PoE+ power. Thus, for a PoE+ switch to receive PoE+
power from a power supply in the chassis, it has to be connected to one of
those ports. PoE+ switches that are connected to RPS 1 or 3 port will not
receive extra PoE+ power, only redundant system power.
23
Chapter 1: Overview
Caution
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 highpower 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.
Table 3. Low-power and High-power Switches

AT-x610-24Ts/X-POE+AT-x610-48Ts/X-POE+
AT-x610-24SPs/X
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 highpower switches for the power modules.

Switches for a Power Supply Module

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.

In the first example, the AT-RPS3000 Chassis, with one power supply
module in slot A, is supporting a single low-power switch, connected to the
RPS 1 System port. (The RPS 3 System and RPS 4 PoE+/System ports
do not have power because slot B is empty.) The non-PoE+ AT-x610-24Ts
Switch places its non-removable, internal power supply module in a
redundant state, and receives all of its system power from the
AT-RPS3000 Chassis and the power module in slot A. If there is an
interruption of system power from the chassis, the switch automatically
activates its internal power supply to maintain network operations.

It should be noted that even though the switch in the example is a nonPoE+ model, the power supply module in slot A can be any of the three
available power modules, including the AT-PWR800 and AT-PWR1200
Modules. The three modules may be used to provide system power to
PoE+ and non-PoE+ switches.
Non-PoE+ switches may be connected to either the RPS System or PoE+/
System port on the chassis. Non-PoE+ switches connected to an RPS
PoE+/System port receive system power, but no power for PoE+, even if
the power supply in the corresponding slot in the chassis contains a PoE+
module. This principal is illustrated in Figure 8 on page 26 where the single
low-power, non-PoE+ switch from the previous example is now connected
to the RPS 2 PoE+/System port, from which it receives just system power.

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 nonremovable 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 lowpower switches.

The chassis must have a second power supply to support three or four
low-power switches, as illustrated in the following example. The power
module in slot A supports switches 1 and 2, and the module in slot B
powers switches 3 and 4.
The power supply modules in the chassis may be the same or different
models. For instance, you might install two AT-PWR250 Modules or
perhaps two AT-PWR1200 Modules. You may also combine the
AT-PWR800 and AT-PWR1200 Modules in the chassis, installing one of
each model in the slots. However, you may not combine the AT-PWR250
Module with the AT-PWR800 or AT-PWR1200 Module in the chassis, as
explained in “Power Supply Modules” on page 19.

The power supply modules can support just one high-power switch at a
time. In the example in Figure 11 on page 28, the chassis is supporting the
AT-x610-24Ts and AT-x610-48Ts Switches, with two power supply
modules, one for each switch. Even though the AT-x610-24Ts Switch is a
low-power unit, the AT-x610-48Ts Switch must have its own dedicated
power supply module because it is a high-power device.

Figure 11. Example of Low-power and High-power Switches
When a high-power, non-PoE+ switch is connected to the AT-RPS3000
Chassis, it responds just like a low-power switch. It places its internal
power supply in the redundant state and draws its system power from the
chassis.
In Figure 12 on page 29, the high-power, non-PoE+ AT-x610-48Ts and
AT-x610-48Ts/X Switches are supported by separate power supply
modules, with the AT-x610-48Ts Switch supported by the module in slot A
and the AT-x610-48Ts/XSwitch powered by the module in slot B. If the
chassis stops supplying system power to the switches, they activate their
internal power supplies.
