j. While grasping the center of the new processor, orient the side of the assembly with the square
notch towards the latching arm, which is on your left when facing the rear of the tower. Align the
holes in the processor assembly with the guide pins on the board and press down until it is fully
seated.
k. Pivot the latching arm down over the processor assembly. Install and start by hand, the 3/8″
(9.5mm) hex head screw/spring assembly, then tighten (it is preferable that you use a nut driver
and not a ratchet) until it stops turning.
Attention: This is a compression fitting, so be careful not to over tighten the screw.
l. Complete the repair by reversing the removal procedures. After exchanging an item, go to Verify
the repair.
This
ends the procedure.

You are removing a card in the Model 830/SB2 (FC 9074) base I/O tower. Perform the following
steps:
a. Open the rear cover. See Models 830/SB2 with FC 9074 - Covers.
b. Remove the EMC access plate that is located directly above the lower card enclosure in the (FC
9074) base I/O tower. Press the two latching mechanisms together and tilt the top of the cover
away from the frame to remove it. Refer to Figure 4. in Final assembly, rear - Models 830 and
SB2 with FC 9074 (See page 406).
c. Remove the mounting screws from the card enclosure.
d. Disconnect and label the cables that are attached to the back of the card enclosure.
e. Slide the card enclosure partially out of the frame.
f. Disconnect and label any cables from the card that you wish to remove.
g. Turn the latch counter clockwise and lift up on the black latch to release the card.
Note: 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 procedure. After exchanging the failing item, then 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
(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 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.
Models 830/SB2 with FC 9074 - Covers
For use by authorized service providers.
Use this procedure to remove or replace the covers on the Model 830/SB2 with FC 9074.
Attention: If removing the cover while powered on, errors may occur due to Electromagnetic Interference.
Note: The front and rear covers will swing open a little more than 90 degrees. This makes it possible to
replace all FRUs, without having to remove the covers.
To open or remove the bottom front cover, refer to the figure below and perform the following steps:
