3) Starting with the brush in the center of the processor contact surface
that is on the system backplane, use an outward brushing motion to
clear the debris away from the area where the surfaces of the processor
module assembly and the system backplane assembly meet.
Be careful
not to brush over the contact surface again . Then, continue brushing
around and away from the perimeter of the contact surface area (out
approximately 6mm or more on all 4 sides of it).
Do NOT brush the
processor module or the contact surface on the bottom of the
processor module
.
j. While grasping the center of the new processor, orient the side of the
assembly with the square notch towards the latching arm, which is on your
left when facing the rear of the tower. Align the holes in the processor
assembly with the guide pins on the board and press down until it is fully
seated.
k.
Pivot the latching arm down over the processor assembly. Install and start
by hand, the 3/8
″
(9.5mm) hex head screw/spring assembly, then tighten
(it is preferable that you use a nut driver and not a ratchet) until it stops
turning . This is a compression fitting, so be careful NOT to over tighten
the screw .
l. Complete the repair by reversing the removal procedures.
m. After exchanging an item, go to “Verifying the Repair” on page 920.
This ends the procedure.
30. You are removing a card in the Model 830/SB2 (FC 9074) Base I/O tower
using Dedicated Maintenance.
Open the rear cover (see “Models 830/SB2
with FC 9074 – Covers” on page 663).
31.
Remove the EMC access plate that is located directly above the (lower) card
enclosure in the (FC 9074) Base I/O Tower. Press the two latching mechanisms
together and tilt the top of the cover away from the frame to remove it. Refer
to “Models 830 and SB2 with FC 9074 - Final Assembly, Rear” on page 820.
32. Remove the mounting screws from the card enclosure. Refer to “Models 830
and SB2 with FC 9074 - Final Assembly, Rear” on page 822.
33. Disconnect and label the cables that are attached to the back of the card
enclosure.
34. Slide the card enclosure partially out of the frame.
35. Disconnect and label any cables from the card that you wish to remove.
36.
Turn the blue latch counter clockwise and lift upward on the black latch to
release the card.
Note: If you are removing a FC 2890, then remove the screws from the tail
stock and slide the card cage forward about 6 inches, then the FC 2890
can be removed or inserted.
37. Remove the card by gently pulling it out.
38. Install the new card by reversing the procedure.
39. After exchanging the failing item, then go to “Verifying the Repair” on
page 920.
Note:
If you have exchanged a 2766 Fibre Channel IOA, the IBM 2105 disk
unit subsystem must be updated to use the World-Wide Port-Name of
the new 2766 IOA. This name can be found in the Port worldwide
name field on the iSeries 400 by displaying detail on the 2766 IOA
Logical Hardware Resource information in Hardware Service Manager
in SST/DST. The 16-digit World-Wide Port-Name can also be
