off the system for the FRU that you are exchanging. Go to step 23 (See page 569) to power on
this expansion tower. Continue with the next step.
Yes: Move each of the expansion unit's ac power cords one at a time to the alternate ac power
v
source to prevent the expansion unit from losing ac power. Go to step 21 (See page 569).
21. When the expansion tower or unit is powered off, disconnect the power cord.
22. Remove or install the part using the procedure that sent you here. Then, continue with the next step
in this procedure.
Notes:
a. Ensure that you replace the failing IOP, IOA, or feature card with the same type and model.
b. When IOPs and feature cards are moved or removed, ensure that the configuration rules are
followed.
23. Perform the following:
a. Reconnect the power cord or cords that you disconnected in step 21 (See page 569) or the
power supply cords that you disconnected in step 19 (See page 568).
Note: The tower will automatically power on. However, you will need to finish the steps in this
procedure to complete the power on and restore the system to normal operation.
b. Were you instructed to perform a function 69 to power the tower on?
Yes: Continue with the next step.
v
No: Go to step 23f (See page 569).
v
c. Are you working on a system that has multiple partitions?
v Yes: Continue with the next step.
No: Perform the function 69 (with the control panel set to Manual Mode) from the control
v
panel. See Control Panel Functions in the iSeries Service Functions
information. Then, go to step 24 (See page 570).
d. Are you working in the Primary partition?
v No: Continue with the next step.
v Yes: Perform the function 69 (with the control panel set to Manual Mode) from the control
panel. See Control Panel Functions in the iSeries Service Functions
information. Then, go to step 24 (See page 570).
e. Perform function 69 from the Work with Partition Status display in the Primary partition. Then, go
to step 24 (See page 570).
f. If the Packaging Hardware Resources display is available, specify the Power on option for the
expansion tower or unit you were working on and press Enter.
Note: In some cases, FRU replacement may generate a new SPCN ID in both the expansion
tower control panel and in HSM. If this occurs, use the new SPCN ID to complete the power on
procedure.
g. If the Packaging Hardware Resources display is not available, select (with the control panel set
to Manual Mode) the SPCN control panel function to power on the expansion tower or unit. See
Control Panel Functions in the iSeries Service Functions
information.
1) Select function 07 and press Enter.
