PS Series support provider for information about returning hardware.
Installing a Control Module
You can install a control module without shutting down the array.
Replace control modules with the same type only.
Control modules are installed horizontally in the array, with the Ethernet ports on the left and the serial port on
the right.

4. Rotate the lever inward, which pushes the control module completely into the slot. The latch on the lever will
snap into place.
