Redundant With Reboot
Redundant With Reboot
By using a second mode of redundant operation called redundant with reboot, you can
connect more hubs and switches to the Cisco RPS and thereby extend its capacity. This
configuration also provides switches and hubs (except the HP 10BaseT Hub-16M) with
additional redundancy.
Redundancy with reboot works for the following devices only: FastHub 100 series,
FastHub 200 series, or FastHub 300 series 100BaseT hubs, Catalyst 1900 series,
Catalyst 2820 series switches, and the Catalyst 2900 series XL switches.
Cisco recommends that you use configurations without the AC power plug (that is,
Note
not in redundant-with-reboot mode) connected to the external device, due to the reboot and
downtime—approximately 30 seconds.
The redundant-with-reboot configuration is shown in Figure 1-5, where a straight-through
one-to-one cable connects an external device (the figure shows switches, but they could also
be hubs) to the Cisco RPS while the device is simultaneously powered by its own internal
power supply (the device AC power plug is connected).
