Replacing the Micro SD Card
Each control module includes a micro SD card running the PS Series array
firmware. If a control module fails, remove the micro SD card from the failed
control module and install the card in the replacement control module. This will
make sure that the new control module is running the correct firmware.
You can access the micro SD card by sliding the control module
partially
from the
slot. If you completely remove the control module, place it on a surface that is
protected from electrostatic discharge.
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 gree), 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
•
See
on page 3-8 for instructions on removing a
control module.
Caution:
Be careful not to damage the circuit board. Do not use sharp
instruments to remove the micro SD card.
Removing the Micro SD Card
1. Firmly push the card into its housing to release the spring mechanism
(Figure 3-8). The micro SD card will be partially ejected from the housing.
