If the command is not found in the Catalyst 4500 Command Reference, it is located in the larger Cisco
IOS library. Refer to the

Overview of Supervisor Engine Redundancy
Catalyst 4500 series switches allow a standby supervisor engine to take over if the primary supervisor
engine fails, thereby allowing the switch to resume operation quickly in the event of a supervisor engine
failure. This capability is called supervisor engine redundancy. In software, this capability is enabled by
route processor redundancy (RPR) operating mode.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
