When a recoverable error is found by memory scrubbing, the Memory ProteXion feature writes the data that was to be stored in the damaged memory locations to spare memory locations within the same DIMM. Removing and replacing a memory card At least one memory card with one pair of DIMMs must be installed for the server to operate correctly. Replacing a memory card Complete the following steps to replace a memory card: 1. Read the safety information beginning on page v and "Installation guidelines" on page 20. 2. Remove the cover from the server (see "Removing the cover and bezel" on page 22). 3. Prepare the new memory card to go into the server: a. Touch the static protective package that contains the memory card to any unpainted surface on the outside of the server; then, remove the memory card from the package. b. Lay the static protective package on a flat surface and place the memory card on top of it. c. Install memory DIMMs in the memory card (see "Installing memory modules" on page 36). 4. Remove the memory card from the server: a. Make sure that the retention levers on the edge of the memory card are fully open. b. Lift the memory card out of the server and set it aside. 5. Replace the memory card: a. Grasp the new memory card by the retention levers and turn the memory card so that the connector aligns with the connector on the microprocessor board. b. Insert the memory card into the memory card connector. c. Press the memory card into the connector and close the small retention lever. d. Wait two seconds and close the large retention lever. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 46. Hot-replacing a memory card To hot-replace a memory card, memory mirroring must be enabled. See "Active Memory" on page 33 for information on how to enable memory mirroring. Complete the following steps to hot-replace a memory card in the server: Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on. 1. Read the safety information beginning on page v and "Installation guidelines" on page 20. Chapter 2. Installing options 35

When
a
recoverable
error
is
found
by
memory
scrubbing,
the
Memory
ProteXion
feature
writes
the
data
that
was
to
be
stored
in
the
damaged
memory
locations
to
spare
memory
locations
within
the
same
DIMM.
Removing
and
replacing
a
memory
card
At
least
one
memory
card
with
one
pair
of
DIMMs
must
be
installed
for
the
server
to
operate
correctly.
Replacing
a
memory
card
Complete
the
following
steps
to
replace
a
memory
card:
1.
Read
the
safety
information
beginning
on
page
v
and
“Installation
guidelines”
on
page
20.
2.
Remove
the
cover
from
the
server
(see
“Removing
the
cover
and
bezel”
on
page
22).
3.
Prepare
the
new
memory
card
to
go
into
the
server:
a.
Touch
the
static
protective
package
that
contains
the
memory
card
to
any
unpainted
surface
on
the
outside
of
the
server;
then,
remove
the
memory
card
from
the
package.
b.
Lay
the
static
protective
package
on
a
flat
surface
and
place
the
memory
card
on
top
of
it.
c.
Install
memory
DIMMs
in
the
memory
card
(see
“Installing
memory
modules”
on
page
36).
4.
Remove
the
memory
card
from
the
server:
a.
Make
sure
that
the
retention
levers
on
the
edge
of
the
memory
card
are
fully
open.
b.
Lift
the
memory
card
out
of
the
server
and
set
it
aside.
5.
Replace
the
memory
card:

Hot-replacing
a
memory
card
To
hot-replace
a
memory
card,
memory
mirroring
must
be
enabled.
See
“Active
Memory”
on
page
33
for
information
on
how
to
enable
memory
mirroring.
Complete
the
following
steps
to
hot-replace
a
memory
card
in
the
server:
Attention:
Static
electricity
that
is
released
to
internal
server
components
when
the
server
is
powered-on
might
cause
the
server
to
halt,
which
could
result
in
the
loss
of
data.
To
avoid
this
potential
problem,
always
use
an
electrostatic-discharge
wrist
strap
or
other
grounding
system
when
working
inside
the
server
with
the
power
on.
