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.
Caution
Changing Between Version 1, Version 2, Version 3, AC, and DC Power Modules
The
pwrmod_change
command is not supported on the Cisco ASR 9912 Router and Cisco ASR 9922 Router.
Note
Follow these steps when changing between version 1, version 2, version 3, AC, and DC power modules:
Procedure
Step 1
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.
Step 2
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.
Example:
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
Step 3
Enter your new power module type.
Example:
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 single power shelf
2)
DC power supply version 1, fits 3 across in single power shelf
3)
AC power supply version 2, fits 4 across in single power shelf
4)
DC power supply version 2, fits 4 across in single power shelf
5)
AC power supply version 3, fits 3 across in single power shelf
6)
DC power supply version 3, fits 4 across in single power shelf
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
