THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

CHAPTER

Product Overview
The Cisco RPS 675 Redundant Power System (RPS), model
PWR675-AC-RPS-N1=, provides N+1 redundancy. The RPS 675 provides
seamless failover to internal power supply failures for one of up to six switches.
The RPS 675 automatically senses when a connected device has experienced an
internal power supply failure. It then begins to supply power to the device. The
RPS supplies power until the power supply of the failed device is replaced or the
device is replaced. You can then return the RPS to active mode so that it is
available to supply power to another device.
Note The RPS 675 does not support an automatic switchover to the internal power
supply. You must press the Standby/Active button on the RPS so that the switch
again uses the internal power supply.
If a connected device fails, the RPS 675 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 RPS 675.
78-15201-04
Note The RPS 675 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.

Amber The RPS is in standby mode or in a fault condition.
Standby/Active Button
The RPS 675 has a front panel Standby/Active button.
Note The RPS is in active mode (Standby/Active LED green) when it powers up.
It must be in standby mode every time you connect devices to it.
If you connect a device to the RPS when it is in active mode (Standby/Active LED
green), the RPS 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 RPS does not immediately sense that the device power supply was supplying
power. In this case, the RPS would not be available as a backup power source for
other connected devices.
Figure 1-3 shows the Standby/Active button. Press the Standby/Active button to
change the RPS 675 from active mode to standby mode when you connect devices.
When you change the mode to active, the Standby/Active LED turns green.
