4. After replacing a part, go to Verify the repair.
This ends the procedure.
Model 825 - Cards (dedicated)
For use by authorized service providers.
Use this procedure to remove or replace cards using dedicated maintenance in the Model 825.
Attention: All cards are sensitive to electrostatic discharge. See Work with electrostatic
discharge-sensitive parts.
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)
To remove or replace cards using dedicated maintenance:
1. In some cases you do not need to power down the system to change PCI cards. Use the guidelines in
Model 825 - Cards (concurrent) to determine if you should use dedicated or concurrent remove and
replace procedures.
2. Choose from the following options:
v If you can perform this procedure concurrently, see Model 825 - Cards (concurrent).
v If you must perform this procedure dedicated, perform the following:
a. Power off the system. See Power on/off the system and logical partitions.
b. Remove the ac power cord on the frame you are working on. On a Model 825 with a system unit
expansion attached, disconnect both the system line cord and the expansion unit line cord.
3. Remove the left side cover. See Model 825 - Covers.
4. Are you removing a processor or memory DIMM?
v Yes: Perform the following:
a. Loosen the thumb screw on the processor enclosure cover, and remove the cover.
b. Open the latches on the identified processor and remove the processor.
c. If you are replacing the processor, label the memory DIMM locations so that they can be
reinstalled in the same position.
d. Press down on the latches that are located on each side of the memory DIMM to release it from
the backplane.
e. If you are replacing the processor, reinstall the memory DIMMs into the new processor in the
locations in which they were originally located and reverse this procedure.
This
ends the procedure.
v No: Remove and label any cables connected to the card.
5.
Either turn the latches securing the card or unscrew the bracket securing the card.
6. Gently pull the card off the system backplane.
7. To install the card, reverse this procedure.
Note: If you have exchanged a 2766 or 2787 Fibre Channel IOA, the IBM
(R)
2105 disk unit subsystem
must be updated to use the World-Wide Port-Name of the new 2766 or 2787 IOA. This name can be
found in the Port worldwide name field on the iSeries
(TM)
by displaying detail on the 2766 or 2787 IOA
Logical Hardware Resource information, in Hardware Service Manager in SST/DST.
The 16-digit World-Wide Port-Name can also be determined by appending the digits ″1000″ to the
beginning of the 12-digit IEEE Address found on the tailstock label of the Fibre Channel IOA. Use the
ESS Web Interface User’s Guide (SC26-7346) to update the World-Wide Port-Name in the host
configuration on the IBM
(R)
2105 ESS. The ESS Web Interface User’s Guide can also be found at the
following URL: http://ssddom02.storage.ibm.com/disk/ess/documentation.html
