13. If you are replacing a processor capacity card that was associated with processor-on-demand (POD)
processor features, perform the following:
a. Contact your second level of support to determine if a POD activation code is required to reset
previously activated on-demand processors.
b. If necessary, a new POD activation code will need to be generated and then entered at the
server.
c. After entering a POD activation code, 30 minutes should elapse before an IPL is performed to
ensure the POD activation code has been saved.
Note:
DST/SST options to activate POD will not be visible if the system password has been
bypassed.
14. Replace the primary Network interface controller (NIC) card. See Models 870 and 890 - Network
interface controller (NIC) card.
15. Replace the DCA books and blanks that you removed earlier. See Models 870 and 890 - DC
converter assembly (DCA).
16. Replace the MSA (air mover) enclosure. See Models 870 and 890 - MSA (air mover) enclosure.
17. Plug in the power cord, and power on the system. See Power on/off the system and logical
partitions.
This
ends the procedure.
Models 870 and 890 - MDA (air mover) controller
For use by authorized service providers.
Use this procedure to remove or replace the motor drive assembly (MDA) controller on the Models 870
and 890. The MDAs are mounted on the face of each motor scroll assembly (MSA), and are separately
removable without removing the MSA.
To remove the MDA controller:
1. Do not power down the system if it is powered on; this procedure can be done concurrently.
2. Open the cover to access the field replaceable unit (FRU). See Models 870 and 890 - Covers.
