Product Overview
The RPS1000 provides N+1 redundancy. The RPS1000 provides seamless failover to internal power
supply failures for one of up to six switches. The RPS1000 automatically senses when a connected
device has experienced an internal power supply failure. It then begins to supply power to the
device. The RPS1000 supplies power until the power supply of the failed device is replaced or the
device is replaced. You can then return the RPS1000 to active mode so that it is available to supply
power to another device.
If a connected device fails, the RPS1000 sends status information to the other connected devices and
to network management software.
This status information alerts administration that these devices are not supported until the failed
device or the power supply of the failed device is brought up or replaced. To achieve one-to-one
redundancy, you must connect each device to a different RPS1000.
The RPS1000 was designed to support specific Linksys Business Series products. Connectors are not
interchangeable.
Consult your switch documentation to determine if it supports the RPS1000 product.
Features
The Linksys Business Series RPS1000 is shown in the figure below.
NOTE: The RPS1000 is designed to provide backup for
internal power supply failures of connected device power
supplies. It is not designed to act as a backup power
source that protects against losses of power due to
external power outages. We recommend using an
uninterruptable power system (UPS) as protection against
power outages.

The RPS1000 has these features:
• Six output channels to support multiple devices
• RPS1000 status information available through the network management application on the
device
• Front-panel LEDs to show status for each output channel, internal power supplies, fans, and
temperature
• Quick switch over capability to ensure that the switch does not reboot if the internal switch
power supply should fail
• Support for the SFE2000/2000P and SGE2000/2000P Ethernet switches
• Small form-factor suitable for rack-mounting to provide maximum wiring closet port density
• Two output levels:
– –48 VDC / 5.6A
– 12 VDC / 8.5A
The two output levels provide a maximum total output power of 380 W. The –48 VDC mode
powers telephone systems in Power over Ethernet (PoE) switches.
• A single 48-inch (1.2-meter) 16-pin-to-14-pin connector cable (part number: RPSCBL1) to
allow connection to an external device. Additional cables can be ordered separately.

STBY/ACTIVE Button
The RPS1000 has a front panel STBY/ACTIVE button.
If you connect a device to the RPS1000 when it is in active mode (STBY/ACTIVE LED green), the
RPS1000 might unnecessarily begin supplying backup power to the device. This situation might
occur if you connect the device before it is powered up, or if the RPS1000 does not immediately
sense that the device power supply was supplying power. In this case, the RPS1000 would not be
available as a backup power source for other connected devices.
Press the STBY/ACTIVE button to change the RPS1000 from active mode to standby mode when you
connect devices. When you change the mode to active, the STBY/ACTIVE LED turns green.

16-pin connector plugs into the RPS1000, and the 14-pin connector plugs into the device. Use only
the Cisco cable for this connection.
Deployment Strategies
You can deploy the RPS1000 in a variety of situations with mission-critical applications.
One application might be in a voice and data network in which Linksys Business Series switches are
connected to Linksys Business Series IP phones and PCs. Connecting an RPS1000 to the switches can
prevent voice network failures that are caused by switch failures.
Another application might be that of using traditional data 10/100/1000 Ethernet switches that
carry mission-critical data. These applications would typically use one RPS1000 to support one to
six switches as shown below.
In this configuration, if one device has a power-supply or power-related failure, the RPS1000
immediately begins to supply power to this device and is no longer available as a backup power
source for the other devices. The RPS1000 sends status information to network management
software to alert the system administrator that the other devices are not supported until the failed
device or the power supply in the failed device is repaired or replaced.
WARNING: Attach only the RPS1000 cable (part #
RPSCBL1) to the RPS1000 receptacle.

Site Requirements
Be sure to observe these requirements as you determine where to place the RPS1000:
For proper operation, where you locate the RPS1000 is extremely important. If the equipment is
placed too close together, the ventilation is inadequate, and panels are inaccessible, malfunctions
and shutdowns might result, and maintenance will be difficult.
Consider this information when you plan the location of the chassis:
• Provide for access to both the front and rear panels of the RPS1000.
• Make sure that the room where the RPS1000 operates has adequate ventilation. Ambient
air temperature might not cool equipment to acceptable operating temperatures without
adequate ventilation. See the RPS1000—Business Series 380W RPS Quick Installation
Guide for temperature requirements.

Planning Your Rack-Mount Installation
Consider this information when you plan your equipment rack installation:
• Enclosed racks must have adequate ventilation. Make sure that the rack is not congested
because each unit generates heat. The intake ports of equipment that is located higher in the
rack can draw heat upward from the equipment that is located near the bottom of the rack.
An enclosed rack should have louvered sides and a fan to provide cooling air.
• When mounting a chassis in an open rack, make sure that the rack frame does not block the
intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis
when it is seated in the rack.
• Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through
the chassis. The best placement of the baffles depends on the airflow patterns in the rack,
which you can determine by experimenting with different configurations.
• When equipment installed in a rack (particularly in an enclosed rack) fails, try this test:
Operate the equipment by itself, if possible. Power off other equipment in the rack and in
adjacent racks to allow the unit under test a maximum of cooling air and clean power.
• Install the RPS1000 and the external devices to which it will connect in adjacent shelves in a
rack.
Tools and Equipment Required
To rack-mount the RPS1000, you need these tools and equipment:
• Number 12 Phillips screwdriver
• Number 8 Phillips screwdriver
• Screws for attaching the brackets to the RPS1000 and the RPS1000 to the rack
• Rack-mount brackets (19-inch or 24-inch) from the accessory kit
WARNING: To prevent bodily injury when mounting or
servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The
following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the
rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack,
load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices,
install the stabilizers before mounting or servicing
the unit in the rack.

Attaching the Brackets to the RPS1000
The bracket orientation and the screws that you use depend on whether you are attaching the
brackets for a 19-inch or a 24-inch rack. Use two of the supplied screws to attach each bracket,
according to the following guidelines:
• For a 19-inch rack, use the supplied number-8 Phillips flat-head screws to attach the long
side of the bracket to the RPS1000.
• For a 24-inch rack, use the supplied number-8 Phillips truss-head screws to attach the short
side of the bracket to the RPS1000.
You can install the RPS1000 into a rack with either the front panel or the rear panel facing forward.
The following figures show how to attach a bracket to one side of the RPS1000 for installation into
19-inch or 24-inch racks with the front panel facing forward The device can also be mounted so that
the rear panel of the RPS1000 faces forward.
NOTE: If you install the switch in a 24-inch rack, an
optional bracket kit that is not included with the switch is
required. You can order a kit that contains the 24-inch
rack-mounting brackets and hardware from Cisco (part
number RCKMNT-1RU=).
NOTE: If you plan to use the optional cable guide, you
should mount the RPS1000 with the rear panel forward.

Mounting the RPS1000 in a Rack
After the brackets are attached to the RPS1000, use the four supplied number-12 Phillips machine
screws to securely attach the brackets to the rack, as shown below.
Connecting the RPS1000
CAUTION: Make sure that the RPS1000 is either in
standby mode or that the RPS1000 AC power is
disconnected before you connect the RPS1000 to a
switch. This precaution is necessary because when you
connect the RPS1000 to the AC power, the RPS1000
automatically becomes active.
NOTE: Do not use different power sources to power up
the RPS1000 and the connected device. If you connect to
separate AC power sources, reset conditions might occur.
