Removing A Power Cooling Module - Lenovo Storage D1212 Hardware Installation And Maintenance Manual

Do not remove covers from the PCM. Danger of electric shock inside. Return the PCM to your supplier for
repair.

Removing a Power Cooling Module

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 (see Figure 71 "Removing a PCM (1) " on page
76).

4. Grip the handle and withdraw the PCM, taking care to support the base of the module with both hands,
as you remove it from the enclosure. (See Figure 72 "Removing a PCM (2) " on page 77).
