3. Choose one of the following:
v If you are removing a processor capacity card card or an interactive card from the processor tower
display panel, then go to Model 840/SB3 processor tower, FC 8079-001 (lower half), and FC 9079 -
Control panels (NB1).
v If you are removing cards in a FC 9079 or the lower half of a FC 8079-001, then go to step 5 (See
page 79).
v Otherwise, you are removing a card in the processor (system) tower. Continue with the next step.
4. To remove a card in the processor (system) tower, perform the following:
a. Remove the front or rear cover to access the card you are replacing. See Models 840/SB3 -
Covers.
b. Remove the EMC access plate for the card location that you are accessing. See Final assembly,
front - Models 840 and SB3 processor tower or Final assembly, rear - Models 840 and SB3
processor tower.)
c. If there are cables connected to the card, mark their locations and disconnect them from the card.
d. On the opposite ends of the card, press the two latch surfaces together to release each latch.
e. Rotate the latches downward.
f. Pull on both latches at the same time to remove the card from the slot.
g. Intall the new card by reversing the procedure.
h. After exchanging the failing item, go to Verify the repair.
This ends the procedure.
5. To remove a card in the lower half of a FC 8079-001 or the FC 9079 I/O tower, perform the following
from the rear of the tower:
a. Open the rear cover. See Models 840/SB3 - Covers.
b. Remove the EMC access plate that is located directly above the card enclosure. Press the two
latching mechanisms together and tilt the top of the cover away from the frame to remove it. See
Final assembly, rear - Models 840 and SB3 processor tower.
c. Remove the mounting screws from the card enclosure. See Final assembly, rear - Models 840 and
SB3 processor tower.
d. Slide the card enclosure partially out of the frame.
e. Disconnect and label any cables from the card that you wish to remove.
f. Turn the latch counter clockwise and lift up on the black latch to release the card.
g. If you are removing a FC 2890, then remove the screws from the tail stock and slide the card cage
forward about 6 inches, then the FC 2890 can be removed or inserted.
h. Remove the card by gently pulling it out.
i. Install the new card by reversing the the procedure.
j. After exchanging the failing item, go to Verify the repair.
Note: If you have exchanged a 2766 or 2787 Fibre Channel IOA, the IBM 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 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 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
This ends the procedure.
