Chapter 3. Procedure

• If the NAM is boxed, unpack it, retaining all packaging and extras. Note the location of all packaging and contents. Photograph if necessary.

  Note: The package will contain a loose model/serial number label. Take care not to mislay this.

• Loosen by a few turns but do not remove 4 × screws holding the rack ears to the NAM's side panels:

  

  This allows the top panel to be removed without it being scratched by the ears.

• Remove and retain 8 × M3 screws securing the top panel to the NAM:

  

• Slide the top panel a few millimetres backwards and then lift it off and away.

  Caution - ESD: The circuit boards contained within the NAM include components which can be damaged by electrostatic discharge. Always work on a properly grounded dissipative surface and wear a suitable grounded wristband. Ground yourself by touching an earthed conductor before removing the disk from its packaging or touching any of the circuit boards.

• Reach beneath the plastic rail to access the retaining clip on the SATA connector (pictured) and remove the connector from the SSD:

  

• Remove and retain the 4 × M3 screws and the 4 × M3 nylock nuts attaching the SSD mounting plate to the base of the NAM.

• Cut the cable ties securing the SSD's power lead to the plastic rail.

• Cut the cable tie securing the red SATA cable to the tie clip on the disk.

• Lift the SSD mounting plate away, disconnecting the power cable when it becomes accessible.

  Note: Take note of the orientation of the SSD with respect to the mounting plate: it is not symmetrical and must be replaced in the correct orientation.

• Remove and retain 4 × M3 screws securing the SSD to the SSD mounting plate and remove the old SSD.

• Secure the new SSD to the SSD mounting plate using the 4 × M3 screws previously removed

• Pass the SATA and power cables beneath the black plastic rail and reconnect them both to the SSD, taking care to push the connectors fully home.

  Note: The cables must pass underneath the black plastic rail.

• Secure the SSD mounting plate to the base of the NAM using the 4 × M3 screws and the 4 × M3 nylock nuts previously removed.

• Attach the 20 mm × 20 mm self-adhesive cable-tie clip to the front left-hand corner of the SSD.

• Secure the red SATA cable to the self-adhesive cable-tie clip with a cable-tie and trim the end of the cable-tie.

• Secure the power cable to plastic rail with a cable-tie and trim the end of the cable-tie.

• Replace the NAM's top panel and temporarily secure it with one × M3 screw in the centre back position on the top.

• Power up NAM and check that it boots (i.e. that it shows information on its display other than the "PicoLED" banner).

• Power down the NAM by holding the power switch for three seconds.

• Secure the top panel with the remaining 7 × M3 screws.

• Re-tighten the 4 × rack ear screws.

• Repack as before.

This completes the procedure.
