Inserting or removing the microSD card

The microSD card is used to store backups. Backups, once generated, are encrypted with a system passphrase that is stored in the controller. You must re-enter this same passphrase to restore a backup from the microSD card, using a serial connection to the unit’s Debug port.
Prerequisites: You are working in a static-free area and have discharged any static from your body. Otherwise, equipment damage is likely to occur.

Perform the following steps:
  1. If the unit is currently running, shut it down and unmount it from any DIN rail or screw-tab mounting.
    For the shutdown procedure refer to “Initiating a controller shutdown.” Accessing the card uses the space behind the mounting base.

    Typically, the microSD card never needs removal. However, in the case where a controller has been electrically damaged or found to be faulty, you can remove the card and install it in another like unit, so it can become a functional replacement.

  2. To open the plastic shutter, carefully slide it open.
    The shutter should remain captive in the base, revealing the microSD card socket.
  3. To insert the microSD card, slide it into card carrier, label side up, until the spring catch engages.
    If properly inserted, the card is behind the shutter track.
  4. To remove the microSD card, push it in until the spring release pushes it partially out of the card carrier, grasp the card, pull it completely out of the unit and store it in a static free protective case.
  5. Carefully slide the card shutter back over the card carrier opening until it clicks in place.
    When properly closed, the shutter should not protrude behind the mounting base.
