Replacing a PCM

Edit online

The Power Cooling Module (PCM) is hot-swappable and therefore removal and installation may be performed by the user.

CAUTION:
Do not remove the cover from the PCM due to danger from electric shock inside. Return the PCM to your supplier for repair.

Removing a PCM

Important: Operation of the enclosure with any modules missing will disrupt the airflow and the drives will not receive sufficient cooling. It is essential that all apertures are filled before operating the enclosure system.
Important: Prior to removing the PCM, disconnect the power from the PCM, by either the mains switch (where present) or by physically removing the power source in order to ensure that your system has warning of an imminent power shutdown. A faulty PCM must be replaced by a fully operational PCM within 24 hours.
  1. Ensure that you identify the faulty PCM correctly.
  2. Switch off and disconnect the power supply cord.
  3. Grasp the latch and the side of the PCM handle between thumb and forefinger, squeeze together and open the handle to cam the PCM out of the enclosure , as shown in the following figure.

Installing a PCM

Important: Handle the PCM carefully and avoid damaging the connector pins. Do not install the PCM if the following conditions exist:
  1. Check for damage, especially to all connectors.
  2. With the PCM handle in the open position, slide the module into the enclosure as shown in the following figure.

  3. Cam the module home by manually closing the PCM handle. A click should be heard as the handle latch engages as shown in the following figure.

  4. Connect the power cables to the power source and to the PCM.
  5. Secure the strain relief bales.
