1. Power off the expansion unit. See the Expansion unit power procedure.
2. Remove the ac power cord from the frame that you are working on.
3. Remove the cover to access the card that you are removing from the system. See FC 5074, FC 5079,
FC 5094, FC 5294, FC 9079, or FC 9094 - Covers.
4. 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.
5. Disconnect and label any cables from the card that you wish to remove.
6. If you are removing an IXS card, then go to Type 2890 or 2892 - Integrated xSeries Server (IXS).
7. Turn the latch counter clockwise and lift upward on the black latch to release the card.
8. Gently pull the card off the backplane.
9. Reverse this procedure to replace the card. After exchanging a 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 or 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.
FC 5074, FC 5079, FC 5094, FC 5294, FC 9079, FC 9094 - Covers
For use by authorized service providers.
Use this procedure to remove or replace covers on the FC 5074, FC 5079, FC 5094, FC 5294, FC 9079,
FC 9094.
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.
v To open or remove the front cover, refer to Figure 1. Front cover - removal (See page ) below.
v To open or remove the rear cover, refer to Figure 2. Rear cover - removal (See page ) below.
Perform the following steps to open or remove each cover.
1. Unlock the cover (front only).
2. Open the cover by grasping its right side and pulling it towards you.
3. After opening the cover, press down on lever B, which is located inside along the top, left side of the
cover.
4. Tilt the top of the cover away from the tower, and lift the cover off.
This ends the procedure.
