User view 
Parameter 
file-url: ARP program path + program name 
slot-number: Slot number of the active or standby SRPC. 
primary: Specifies this program to be the primary bootstrap program. 
backup: Specifies this program to be the backup bootstrap program. 
Description 
Use the boot boot-loader primary command to specify the primary bootstrap program 
to be the bootstrap program. 
Use the boot boot-loader backup command to specify the backup bootstrap program 
to be the bootstrap program. 
If the switch cannot be started through specified bootstrap program, a program will be 
selected from the Flash or CF card as bootstrap program. If the switch still cannot be 
started normally, the switch fails to boot up. 
 
î  Note: 
An S8500 series routing switch supports system switchover, both its active and 
standby SRPCs have an application program system. You can operate on the 
programs on both SRPCs. But when you specify a bootstrap program on the standby 
SRPC, the URL of the program must begin with "slot[No.]#[flash: | cf:]/", where, [No.] is 
the slot number of the standby SRPC and [flash: | cf:] is the name of the equipment, 
flash card or CF card. For example, if the slot number of the standby SRPC is 1, the 
URL of the 8500.app program under the root directory on the standby SRPC must be 
"slot1#flash:/8500.app".
