On HA WLC setup, output from "show inventory" displays the standby unit Chassis power supply as unknown or ASR1000 power supply even tough correct PID is used. i.e. below
This bug can also cause the serial number of chassis 1 and chassis 2 to be the same in the "show inventory" output
NAME: "Chassis 1 Power Supply Module 0", DESCR: "Cisco Catalyst Wireless Controller 1100W AC Power Supply"
PID: C9800-AC-1100W , VID: V01 , SN: XXXXXXXXXX
NAME: "Chassis 2 Power Supply Module 0", DESCR: "Cisco ASR1000 Unknown Power Supply"
PID: ASR1000-PWR-UNKNOWN, VID: , SN:
