Deployment Strategies
Another application might be that of using traditional 10/100/1000 Ethernet switches
that carry mission-critical data. These applications would typically use one RPS 2300
to support one to six switches, as shown in Figure 1-3.
In this configuration, both the RPS 2300 and the switches might not share the
same AC power source.

If up to two devices have a power-supply or power-related failure, the RPS 2300
immediately supplies power and is no longer available as a backup source for the
other devices. The RPS 2300 sends status information to the network management
software to alert you that the other devices connected to it are not supported until
the failed device or the power supply in the failed device is repaired or replaced.
To support mission-critical applications, the RPS 2300 must have enough power
to support all connected devices if all of the devices fail. Figure 1-4 shows the
RPS 2300 connected to more than one AC source, with the RPS 2300 and the
switches using different AC power sources. This deployment provides protection
if both a switch power supply and an AC source fail.
