PCI switch card assembly The PCI switch card assembly, mounted on the top rear of the server frame adjacent to the adapter slots, contains one switch for each of the six adapters. This ensures that power is disconnected from the associated adapter if you attempt to open the adapter latch and remove an adapter. Note: v v v Read "Installation guidelines" on page 29. Read "Safety information" on page 147. Read "Handling static-sensitive devices" on page 30. Complete the following steps to remove and replace the PCI switch card assembly: 1. Turn off the server and all peripheral devices; then, disconnect all power cords and external cables. 2. Remove the top cover (see "Removing the cover and bezel" on page 32). 3. Remove all full-length adapters and adapter insulators (see "Removing a PCI or PCI-X adapter" on page 36), making sure to place the adapters on a static-protective surface. 4. Disconnect the PCI switch card assembly cable from the server. 5. Grasp the two adapter switch card release latches and slide the assembly away from the server chassis; then, lift it out of the server. Note: The illustrations in this document might differ slightly from the hardware being serviced. Release latches 6. To replace the PCI switch card assembly, lower the assembly into place so that the lips on the bottom of the EMI shielding material fit into the chassis at the rear of the server, and slide the card into place until the two release latches snap securely. 7. Connect the cable from the PCI switch card assembly to the I/O board and install the adapters and adapter insulators that were removed in step 3. 76 IBM xSeries 365 Types 8861, 8862: Hardware Maintenance Manual and Troubleshooting Guide

rear
of
the
server
frame
adjacent
to
the
adapter
slots,
contains
one
switch
for
each
of
the
six
adapters.
This
ensures
that
power
is
disconnected
from
the
associated
adapter
if
you
attempt
to
open
the
adapter
latch
and
remove
an
adapter.
Note:
v
Read
“Installation
guidelines”
on
page
29.
v
Read
“Safety
information”
on
page
147.
v
Read
“Handling
static-sensitive
devices”
on
page
30.
Complete
the
following
steps
to
remove
and
replace
the
PCI
switch
card
assembly:
1.
Turn
off
the
server
and
all
peripheral
devices;
then,
disconnect
all
power
cords
and
external
cables.
2.
Remove
the
top
cover
(see
“Removing
the
cover
and
bezel”
on
page
32).
3.
Remove
all
full-length
adapters
and
adapter
insulators
(see
“Removing
a
PCI
or
PCI-X
adapter”
on
page
36),
making
sure
to
place
the
adapters
on
a
static-protective
surface.
4.
Disconnect
the
PCI
switch
card
assembly
cable
from
the
server.
5.
Grasp
the
two
adapter
switch
card
release
latches
and
slide
the
assembly
away
from
the
server
chassis;
then,
lift
it
out
of
the
server.

To
replace
the
PCI
switch
card
assembly,
lower
the
assembly
into
place
so
that
the
lips
on
the
bottom
of
the
EMI
shielding
material
fit
into
the
chassis
at
the
rear
of
the
server,
and
slide
the
card
into
place
until
the
two
release
latches
snap
securely.
