Inserting or removing a microSD card
Typically, the microSD card that ships with a new controller is inserted in the unit prior to the mounting process. However,
it is possible to move an SD card from one unit to another. For example, you might want to remove the SD card from a unit
that suffered a hardware failure and use it in a replacement unit.
Prerequisites:
- All power to the controller is removed before inserting/removing the microSD card, otherwise equipment damage may occur.
- The controller is unmounted from any DIN rail or screw tab mounting, as accessing the card uses space behind the mounting base.
- Discharge any static electricity that you may have accumulated by touching a known, securely grounded object.
NOTE: Data on the microSD card is encrypted by a “system passphrase” stored in the controller base. The passphrase on the card must match the passphrase stored in the controller. If swapping in a card from a previously configured unit, you must provide the passphrase (of the previously configured unit which is stored on this SD card) using a serial connection to the unit’s Debug port.
Perform the following steps:
- Carefully slide the plastic microSD card shutter open.The shutter should remain captive in the base, revealing the microSD card socket.

- Insert the microSD card by sliding the card into the card socket, label side up, until the spring catch engages. If properly inserted, the card is behind the shutter track.
- Remove the microDS card by pushing the card in, until the spring release pushes the card partially out of the card socket. Grasp the card and pull it completely out of the unit. Store the microSD card in a static free protective case.
- Carefully slide the card shutter back over the card socket opening, until it clicks into place. When properly closed, the shutter should not protrude behind the mounting base.
