Fc 9094 Base I/O Tower- Control Panel - Nb1 - IBM iSeries 270 Service Manual

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. If you are working on an expansion tower, power off the tower using the Expansion unit power
procedure. If you are working on the base I/O tower for the Model 870 or 890, power off the system
(see Power on/off the system and logical partitions.
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, 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 want to remove.
6. If you are removing an IXS card, then go to Type 2890 or 2892 - Integrated xSeries Server (IXS) for
iSeries.
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 install cards. After exchanging a failing item, go to Verifying 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 server 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.

FC 9094 Base I/O Tower- Control panel - NB1

For use by authorized service providers.
Use this procedure to remove or replace the control panel - NB1 in an FC 9094 Base I/O Tower.
Attention: The control panel including the processor capacity card and interactive cards are sensitive to
electrostatic discharge (see Work with electrostatic discharge-sensitive parts).
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)
To remove or replace the control panel (NB1):
1. Power off the system. See Power on/off the system and logical partitions.
2. Disconnect the ac power cord from the tower that you are working on. Note that dual line cord units
have two power cords.
3. Open the front cover. See FC 5074, FC 5079, FC 5094, FC 5294, FC 9079, FC 9094 - Covers.
4. Perform the following to remove the control panel:
a. Pull on the two side fasteners to release the control panel assembly.
