Use the SHOW UNIT command to determine the software and firmware revision.
All processor modules should load normally, after installing the replacement AC power input
module. The replacement module will have a status of Present. (You can view the status using the
SHOW CHASSIS LOADDUMP CHARACTERISTICS command. Look in the CCS Information
section at the bottom of the display. )You must then change the status of the replacement module
from Present to Current.
To force the replacement power input module to the Current status, you must type a DEFINE
CHASSIS command (for example DEFINE CHASSIS SLOT LOAD IMAGE PROTOCOL CARD
ENABLE) at each processor module to update its chassis parameters.
If you do not update the replacement module, and the other power input module fails, then all control
storage parameters will be lost, and there would a mismatch between the Ethernet address of the
replacement power input module and the names of the parameter files. In this case, you would need
to order a new primary module with a factory-installed Ethernet address .
Type 1 Products. Type 1 processor modules only know about the primary AC power input
module. (A Type 1 option is a Network 9000 product or a MAXserver family product which does
not support chassis management commands, and has a link to midplane Ethernet segment A
only.) Therefore, when the primary AC power input module fails, Type 1 products no longer
function properly.
Powering On Input Modules Incorrectly. You should turn on the AC power input module in slot
1 before you turn on the module in slot 10. If you do not turn these modules on in the correct
order, you can create a situation where the processor modules become confused about where to
obtain initialization configuration data.
