IBM iSeries 270 Service Manual page 17

Attention: All cards are sensitive to electrostatic discharge. See Work with electrostatic
discharge-sensitive parts.
Attention: If removing the cover while powered on, errors may occur due to electromagnetic interference.
The Model 270 or 810 may be housed in a FC 0551 frame. The upper and lower system units are placed
on rails in the frame. If you are working on the upper or lower unit in a 0551 frame, follow these
instructions and access the internal parts by opening the front cover and sliding the system unit out on its
rails.
To remove cards concurrently:
1. From the Hardware Service Manager display, select Packaging hardware resources.
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. Look at the power LED for the card that you are removing to ensure that it is powered off. The power
LED is located to the left and directly above the card slot. If the LED is blinking multiple times per
second (rapidly) or it is off, then the card is powered off.
8. Remove the left side cover. See Models 270, 800, and 810 - Covers.
9. Remove and label any cables connected to the card.
10. Turn the latches securing the card.
11. Gently pull the card off the system backplane.
To replace cards concurrently:
1. Install the card in to the system by reversing the card removal procedure above.
2. Select Power on domain for the IOA or IOP that you are installing.
3. Press Enter. The Work with Controlling Resources display will appear.
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.
4. Determine the location where you want to assign the resource and select Assign to for that location.
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.
