Removing and Replacing Power System Components
Caution Do not turn off the switch on the power tray to remove individual power modules. Power modules
support OIR, so they can be removed and replaced with the power on and the system operating.
Changing Between Version 1, Version 2, Version 3, AC, and DC Power Modules
Follow these steps when changing between version 1, version 2, version 3, AC, and DC power modules:
Step1 Before making any physical changes, check the software configuration to ensure no ROMMON variable
CHASSIS_TYPE (such as CHASSIS_TYPE=10_SLOT) is set to override the chassis type.
Step2 At the Cisco IOS-XR command prompt on the RSP console, run the pwrmod_change command. This
command displays the current power module and system information.
RP/0/RSP0/CPU0:RO9_P2RSP3# run
Wed Jul 4 20:18:58.034 UTC
# pwrmod_change
Current system:
power supply type : AC power supply version 2
chassis type : 10-slot
chassis bpid: 0x2fa, PID: ASR-9010-AC
UDI name: ASR-9010 AC, UDI desc: ASR-9010 AC
Step3 Enter your new power module type.
Please enter the number that corresponds to the power supply type that is being migrated
to. Do not enter the current power system information, use the future power system type.
1) AC power supply version 1, fits 3 across in power shelf ASR-9010-AC
2) DC power supply version 1, fits 3 across in power shelf ASR-9010-AC
3) AC power supply version 2, fits 4 across in power shelf ASR-9010-AC
4) DC power supply version 2, fits 4 across in power shelf ASR-9010-AC
ATTENTION: You are about to commit a change in the power system type for the chassis.
Please confirm that the OLD and NEW power system information listed here is correct. Once
the system software change is committed, you must physically remove the OLD power system
and replace it with the NEW power system of the type specified below here. Any mismatch
between the programmed system value and the actual physical installation may cause boot
and power management issues in the system.
OLD POWER SYSTEM:
power supply type: AC power supply version 2
chassis type: 10-slot
chassis bpid: 0x2fa, PID: ASR-9010-AC
UDI name: ASR-9010 AC, UDI desc: ASR-9010 AC
NEW POWER SYSTEM:
power supply type: DC power supply version 2
chassis type: 10-slot
chassis bpid: 0x2fa, PID: ASR-9010-DC
UDI name: ASR-9010 DC, UDI desc: ASR-9010 DC
