PS6500 Hardware Maintenance Maintaining Control Modules
3-8
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. If you remove the active control module (the
LED labeled ACT will be green), there will be a short interruption as failover to the secondary control module
occurs.
Before replacing a micro SD card:
• Attach an electrostatic wrist strap, as described in Protecting Hardware from Electrostatic Discharge on
page 1-7.
•See Replacing the MicroSD Card on page 3-7 for instructions on removing a control module.
Caution: Be careful not to damage the circuit board. Do not use sharp instruments to remove the microSD card.
Removing the MicroSD Card
1. Firmly push the card into its housing to release the spring mechanism (Figure 3-7). The microSD card will be
partially ejected from the housing.

2. Gently pull the card straight out of the housing.
3. Place the microSD card on a flat surface where it will be protected from electrostatic charge.
