PS6610 Hardware Owner's Manual 3 Control Module Maintenance Using the Standby On/Off button on one member does not affect any other group members, with the exception of the group lead member. When the group lead member is in standby mode, it takes a few minutes for the group lead to fail over to another member. You must press the standby button on each member to restore power to the member that is in standby mode. Group members that do not have the standby button remain online; to shut them down, you must use the GUI or CLI. Replace a Control Module If a control module fails, remove it and replace it with a functioning control module, as described in this section. You will need to swap the battery from the old to the new control module before inserting the replacement control module. You will also need to temporarily remove a control module when you want to replace its microSD card. Refer to Replace the MicroSD Card on page 25 for information about replacing the microSD card. You can partially or completely remove a control module without shutting down the array if the remaining control module has at least one connected and functioning network interface. The procedures for doing this type of control module replacement are described in Control Module Replacement Procedures on page 21. When you remove a control module, wear an electrostatic wrist strap, as described in Hardware Protection on page 6, and be sure to place it on a surface that is protected from electrostatic discharge. Control Module Replacement Procedures This section describes the procedures for removing and replacing one or both control modules in your PS Series array. The following replacement scenarios are covered: • Replacing the secondary control module in an array • Replacing the active control module in an array • Replacing both control modules in an array Replacing the Secondary Control Module If the array is fully powered up and functioning, use the following procedure to replace the secondary control module in the array: 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 SD card in the replacement control module, as described in Insert the MicroSD Card on page 26. 4. Remove and swap the battery from the existing control module to the replacement control module, as described in Battery Replacement on page 27. 5. Insert the replacement control module into the array, as described in Install a Control Module on page 23. Replacing the Active Control Module Use the following procedure to replace the active control module in the array: 21

it
takes
a
few
minutes
for
the
group
lead
to
fail
over
to
another
member.
You
must
press
the
standby
button
on
each
member
to
restore
power
to
the
member
that
is
in
standby
mode.
Group

button
remain
online;
to
shut
them
down,
you

Replace
a
Control
Module
If
a
control
module
fails,
remove
it
and
replace
it
with
a
functioning
control
module,
as
described
in
this
section.
You
will
need
to
swap
the
battery
from
the
old
to
the
new
control
module
before
inserting
the
replacement
control
module.
You
will
also
need
to
temporarily
remove

module
when
you
want
to
replace
its
microSD
card.
Refer
to
Replace

for
information
about
replacing
the
microSD
card.
You
can
partially
or
completely
remove
a
control
module
without
shutting
down
the
array
if
the
remaining
control
module
has
at
least
one
connected
and
functioning
network
interface.
The
procedures
for
doing
this
type
of
