2. Select Hardware contained in packaging for the frame ID that you are working on.
3. Find the card position for the IOA or IOP that you are removing and select Concurrent maintenance.
Attention: If multiple resources are shown with the same card position, one or more of these
resources will show a status of Missing ("?" after the description). Only one resource will be listed as
not missing. Select this resource for the concurrent maintenance operation.
4. A listing of the power domain is shown. Find the IOA or IOP that you are removing and select Power
off domain. Everything within the IOA's or IOP's power domain will be powered off .
5. To see the status of the power domain, select Display power status.
6. Find the IOA or IOP that you are removing and select Toggle LED blink off/on.
7. Remove the cover to access the card that you are removing from the system. See Models 830/SB2
with FC 9074 - Covers.
8. Look at the power LED for the card that you are removing to ensure that it is powered off. The power
LED is located above or in front of the card slot. If the LED is blinking multiple times per second
(rapidly) or it is off, then the card is powered off.
9. From the rear of the tower perform the following:
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 card enclosure. Press the two
latching mechanisms together and tilt the top of the cover away from the frame to remove it. See
Models 830 and SB2 with FC 9074 - Final assembly, rear (See page 406).
c. Disconnect and label any cables from the card that you want to remove.
d. Turn the latch counter clockwise and lift up on the black latch to release the card.
Attention: If you are removing a FC 2890, then you must use dedicated maintenance.
e. Remove the card by gently pulling it out.
f. Install the card in to the system by reversing the card removal procedure for the model system or
tower that you are working on.
g. Select Power on domain for the IOA or IOP that you are installing.
Note: To the right of the description field you will see one or both of the following symbols
displayed.
Symbol Indication
* Indicates the location to which the system will assign the resource.
> Indicates the location to which the resource was last assigned.
h. Press Enter. The Work with Controlling Resources display will appear.
i. Determine the location where you want to assign the resource and select Assign to for that
location.
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.
