FRU Removal and Replacement
I/O Board
This section describes how to remove and replace the I/O board in J5000 and J7000
workstations.
Removing the I/O Board
To remove the I/O board, do the following:
1.
Remove the top panel and the right side panel from the workstation.
2.
Remove the PCI retainer clip by pressing down on the thumb tab and pulling the clip
forward to rotate it out of the chassis floor hole, as shown in Figure 4-49.
Figure 4-49. Removing the PCI Retainer Clip
3.
Remove the power supply by following the removal procedures in “Power Supply” on
page 128.
4.
Remove all I/O cards and note their locations for reinstallation later. See the removal
procedures in “I/O Cards” on page 121 for details.
5.
Remove the one side of the flex cable that is connected to the I/O board. (You do
not
need
to remove the flex cable entirely. That is, you do
not
need to also remove the other side
of the flex cable that is connected to the system board for this procedure.) To do this:
a.
Remove the flex cable retainer covering the flex cable. (The flex cable retainer and
the flex cable are located at the top of the workstation, near the rear. The flex
cable straddles the center wall of the chassis, connecting the I/O board to the
system board.)
b.
On the I/O board side of the flex cable, pull outward on the two
outer corners
of the
flex cable’s ejector handle. The arrows on the flex cable indicate where you should
pull on the ejector handle. (See the CAUTION on the next page.) This disconnects the
flex cable from the system board connector, as shown in Figure 4-50 on the next page.
