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.

25.
3. Install the SD card in the replacement control module, as described in Insert the MicroSD Card on
page 26.
