Attention: The control panel including the processor capacity card and interactive
cards are sensitive to electrostatic discharge (see “Appendix C. Working with
Electrostatic Discharge-Sensitive Parts” on page 955).
CAUTION:
The circuit card contains lead solder. To avoid the release of lead (Pb) into the
environment, do not burn. Discard the circuit card as instructed by local
regulations. (RSFTC234)
1. Power off the system. (See “Powering On and Powering Off the System and
Logical Partitions” on page 922.)
2. Disconnect the AC power cord from the tower that you are working on.
3. Open the front cover. (See “FC 5074, FC 5079, FC 9079 – Covers” on page 623.)
4. Are you working on a FC 9079 tower or the lower half of a FC 8079 tower?
No Yes
↓ Go to step 17 of this procedure.
5. On the processor tower, unfasten the 2 thumbscrews that keep the panel from
hinging forward and swing the panel forward.
6. Loosen the 2 screws that retain the processor capacity card retention (back)
cover and remove the cover.
7. Mark the processor capacity card and interactive cards as to their positions
and orientation, then remove the cards. See “Assembly 8: Models 840 and SB3
– Control Panel, Processor Tower” on page 838.
8. If you are replacing the panel, then you must move the processor capacity
card and interactive card to the new panel.
If you are here to replace the processor capacity card or interactive card, then
replace only that card and not the panel. After replacing the processor
capacity card or interactive card, proceed to step 15 of this procedure.
9. Remove the cables from the panel.
10. Remove the 4 screws on the front bezel and remove it from the hinge bracket.
11. Remove the 5 screws that are retaining the panel card and remove the panel
card.
12. Reverse the above procedure to install the new panel.
13. After exchanging an item, go to “Verifying the Repair” on page 920.
This ends the procedure.
14. Put the control panel back into the frame by reversing the steps that you used
to remove the processor capacity card card or interactive card.
15. If you are replacing a Processor Capacity Card that was associated with one of
the following processor features (Model 840 - CCIN 2416, 2417, 2419, 2352,
2353, or 2354), you MUST contact your second level of support to determine
if a POD activation code is required, to re-set previously activated
ON-Demand processors. If so, then a new POD Activation Code must be
generated and entered at the server.
Note: DST/SST options to activate POD will not be visible if the system
password has been bypassed.
Note: After entering a POD Activation Code, 30 minutes should elapse before
an IPL is performed, (this ensures the POD Activation Code has been
saved).
