PS6610 Hardware Owner's Manual 3 Control Module Maintenance If two control modules are installed in the array, but only one is shown in the GUI (or CLI), make sure that you have allowed enough time (minimum of 5 minutes) for the two control modules to boot and synchronize. When synchronization completes, a message appears on the serial console (if connected), and the ACT LED on the secondary module is illuminated amber. If the GUI (or CLI) still shows only one control module after appropriate time has elapsed, the controller might not be properly installed. Try to remove the module by rotating the black lever and reinsert the module into the array chassis. Ensure that the face of the controller is even with the controller already installed in the array. After reinstalling the control module, if both control modules still do not appear in the GUI (or CLI), contact your support provider. Caution: After a control module is installed in an array, do not restart or reinstall it, or upgrade firmware on the array, until the control module has finished synchronizing its internal firmware with the primary control module. This process occurs in the background and can take up to 45 minutes to complete, depending on the control module type. To verify that the synchronization process has finished, you can check for confirmation messages in the GUI event viewer or by using the CLI command show recent events. If you interrupt the synchronization process, you might corrupt the control module's internal firmware, and the control module will no longer function properly. Replace the MicroSD Card Each control module includes a microSD card that contains the PS Series firmware. If a control module fails, you will need to remove the microSD card from the failed control module and install the card in the replacement control module. Using the card from the failed control module ensures that the new control module is running the same firmware and configuration as the other control module in the array. Before you begin the procedure to replace a microSD card: • Review Replace a Control Module on page 21 for information about removing and replacing a control module. • Attach an electrostatic wrist strap, as described in Hardware Protection on page 6. MicroSD Card Replacement Procedure Use the following procedure for replacing the microSD card in your control module: 1. Remove the control module from the array, as described in Remove a Control Module on page 22. 2. Remove the SD card from the control module, as described in Remove the MicroSD Card on page 25. 3. Install the replacement SD card in the control module, as described in Insert the MicroSD Card on page 26. 4. Insert the control module into the array, as described in Install a Control Module on page 23. Remove the MicroSD Card Callout 1 in Figure 17 shows the location of the microSD card. 25

Control
Module
Maintenance
If
two
control
modules
are
installed
in
the
array,
but
only
one
is
shown
in
the
GUI
(or
CLI),
make
sure
that
you
have
allowed
enough
time
(minimum
of
5
minutes)
for
the
two
control
modules
to
boot
and
synchronize.
When
synchronization
completes,
a
message
appears
on
the
serial
console
(if
con-
nected),
and
the
ACT
LED
on
the
secondary
module
is
illuminated
amber.
If
the
GUI
(or
CLI)
still
shows
only
one
control
module
after
appropriate
time
has
elapsed,
the
con-
troller
might
not
be
properly
installed.
Try
to
remove
the
module
by
rotating
the
black
lever
and
rein-
sert
the
module
into
the
array
chassis.
Ensure
that
the
face
of
the
controller
is
even
with
the
controller
already
installed
in
the
array.
After
reinstalling
the
control
module,
if
both
control
modules
still
do
not
appear
in
the
GUI
(or
CLI),
contact
your
support
provider.
Caution:
After
a
control
module
is
installed
in
an
array,
do
not
restart
or
reinstall
it,
or
upgrade
firm-
ware
on
the
array,
until
the
control
module
has
finished
synchronizing
its
internal
firmware
with
the
pri-
mary
control
module.
This
process
occurs
in
the
background
and
can
take
up
to
45
minutes
to
complete,
depending
on
the
control
module
type.
To
verify
that
the
synchronization
process
has
finished,
you
can
check
for
confirmation
messages
in
the
GUI
event
viewer
or
by
using
the
CLI
command
show
recent
events
.
If
you
interrupt
the
synchronization
process,
you
might
corrupt
the
control
module's
internal
firmware,
and
the
control
module
will
no
longer
function
properly.
Replace
the
MicroSD
Card
Each
control
module
includes
a
microSD
card
that
contains
the
PS
Series
firmware.
If
a
control
module
fails,
you
will
need
to
remove
the
microSD
card
from
the
failed
control
module
and
install
the
card
in
the
replacement
control
module.
Using
the
card
from
the
failed
control
module
ensures
that
the
new
control
module
is
running
the
same
firmware
and
configuration
as
the
other
control
module
in
the
array.
Before
you
begin
the
procedure
to
replace
a
microSD
card:
