Models 270, 800, and 810 - Cards (dedicated)
For use by authorized service providers.
Use this procedure to remove or replace cards using dedicated maintenance on the Models 270, 800, and
810.
The Models 270, 800, and 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.
In some cases for the Models 270 and 810, you do not need to power down the system to change PCI
cards. Use the guidelines in Models 270 and 810 - Cards (concurrent) to determine if you should use
dedicated or concurrent remove and replace procedures.
CAUTION:
The circuit card contains lead solder. To avoid the release of lead (Pb) into the environment, do not
burn. Discard the circuit card as instructed by local regulations. (RSFTC234)
Attention: All cards are sensitive to electrostatic discharge. See Work with electrostatic
discharge-sensitive parts.
To remove or replace cards (dedicated):
1. Power off the system. See Power on/off the system and logical partitions.
2. Remove the ac power cord on the frame you are working on. On Models 270, 800, and 810 with a
system unit expansion attached, disconnect both the system line cord and the expansion unit line cord.
3. Remove the left side cover. See Models 270, 800, and 810 - Covers.
4. Are you removing a memory DIMM?
v Yes: Press down on the latches that are located on each side of the memory DIMM to release it
from the backplane.
This ends the procedure.
v No: Remove and label any cables connected to the card.
5. Either turn the latches securing the card or unscrew the bracket securing the card.
6. Gently pull the card off the system backplane.
7. Reverse this procedure to replace the card.
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.
