It seems that I can't. See below:
Rack1R2#
Rack1R2#sh run int eth 0/0
Building configuration...
Current configuration : 135 bytes
!
interface Ethernet0/0
ip address 173.1.23.2 255.255.255.0
half-duplex
standby use-bia
standby priority 120
standby preempt
end
Rack1R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Rack1R2(config)#int eth 0/0
Rack1R2(config-if)#standby ip 173.1.23.2
% Standby address cannot equal interface IP address
Rack1R2(config-if)#
Rack1R2(config-if)#^Z
Rack1R2#
