By using a mode of operation called redundant with reboot, you can connect more
hubs and switches to the Cisco RPS and thereby extend its capacity or provide
additional redundancy. Redundancy with reboot works for the following devices
only: FastHub 400 series hubs, Catalyst 1900 series and Catalyst 2820 switches,
and Catalyst 2900 series and Catalyst 3500 series XL switches. However, this
configuration is not generally recommended, because a power supply failure will
cause an interruption while the hub or switch reboots.
The redundant-with-reboot configuration is shown in
straight-through one-to-one cable connects an external switch or hub to the
Cisco RPS while the device is powered by its own internal power supply (the
device AC power plug is connected).
