Chapter 6. Module removal and installation
Overview
Important: Always have available a replacement or blank module before removing the old module. When
you replace a module, you must never leave an empty bay in the rear of the enclosure.
ESD precautions
Important: It is recommended that you fit and check a suitable anti-static wrist or ankle strap and
observe all conventional ESD precautions when handling COS small disk enclosure plug-in modules and
components. Avoid contact with midplane components and module connectors.
Replacing a PCM
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.
