AT-RPS1000 Installation
This document describes the features and procedures to install the
AT-RPS1000.
Summary of Features
The features of the AT-RPS1000 are as follows:
❑Provides redundant, load-shared power for up to two gigabit
switches (AT-9108 or AT-8518).
If the primary power supply for the switch fails, the AT-RPS1000
❑Contains two active power supplies (each with its own AC power
connector) that share the load with the primary power supply
located in the gigabit switches.
❑Provides status on power supply and fan operation of the
AT-RPS1000 by way of the gigabit switch’s Simple Network
Management Protocol (SNMP) and command-line interface (CLI).
Information regarding the AT-RPS1000 and fan operation can be
obtained by using the show switch command from the gigabit
switch CLI.
❑Uses a standard 2U, 19-inch rack mount.
❑Has 110/220 VAC autosensing capability.
❑Capable of driving 3.3V at 20A and 5V at 10A on each of its DC
connectors.
❑Supports only Allied Telesyn’s gigabit switches.

If the AT-RPS1000 DC cables are not connected to a gigabit switch, but
the AC power cords are connected to an AC ou tlet, the RPS 1 and RPS2
LEDs will blink. If one of the cables is properly connected to a gigabit
switch, but the remaining cable is not, the unconnected cable will cause
its associated AT-RPS1000 LED to blink.

Power Sockets
Figure 2:
AT-RPS1000 Rear Panel
The AT-RPS1000 has two AC power sockets. The upper AC power socket
(power socket A) provides power to one of the AT-RPS1 000, which
provides redundant load-shared power to the gigabit switch that is
connected to the AT-RPS1000 using the upper AT-RPS1000 port
(AT-RPS1000 port A).
The lower AC power socket (power socket B) provides power to the second
AT-RPS1000, which provides redundant load-shared power to the gigabit
switch that is connected to the AT-RPS1000 using the lower AT-RPS1000
port (AT-RPS1000 port B).
NOTE
The upper power socket powers only the upper AT-RPS1000 port. The
lower power socket powers only the lower AT-RPS1000 port.
If you want to distribute the input AC power source across multiple,
individual circuit breakers, be sure to plug each AT-RPS1000 cord and
switch cord to outlets supplied by different circuit breakers.

Supply Ports
The AT-RPS1000 has two AT-RPS1000 ports. Each port connects to a
different gigabit switch.
Figure 3 shows the rear view of a rack that has one gigabit switch
mounted above the AT-RPS1000 and one gigabit switch mounted below
AT-RPS1000. The upper switch is cabled to the upper AT-RPS1000 port;
the lower switch is cabled to the lower AT-RPS1000 port.
Figure 3:
Note that the upper power socket on the AT-RPS1000 provides the AC
source for backup power for the upper switch; the lower power socket
provides the AC source for backup power for the lower switch.

Installing the AT-RPS1000
To install the AT-RPS1000, follow these steps:
1. Mount the AT-RPS1000 in the equipment rack, or, if the AT-RPS1000
For more information on installing the mounting brackets, see the
Gigabit Switch Installation Guide.
2. Using the supplied DC power cables, connect the cables of the

prior to connecting the respective AT-RPS1000 AC power cord to the AC
outlet.

AT-RPS1000.
NOTE
AT-RPS1000 to each gigabit switch.
NOTE
3. Tighten the screws connecting both sides of the AT-RPS1000 cable.
WARNING
If you do not tighten the screws on both sides of the AT-RPS1000 cable,
the cable could come loose and emit sparks.
4. Connect an AC power cord to each power socket.
5. Plug the power cords into properly grounded AC outlets.
W ARNING
When disconnecting the AT-RPS1000, the AC power cords must be
removed from the AT-RPS1000 before removing the AT-RPS1000 DC
cables.
