Replacing SCv2000/SCv2020 Components 2 This section describes how to remove and install components of an SCv2000/SCv2020 storage system. This document assumes that the customer has received the replacement component and is ready to install it. Safety Precautions Always follow these safety precautions to avoid injury and damage to Storage Center equipment. If equipment described in the document is used in a manner not specified by Dell, the protection provided by the equipment may be impaired.
Electrical Safety Precautions Always follow electrical safety precautions to avoid injury and damage to Storage Center equipment. WARNING: Disconnect power from the storage system when removing or installing components that are not hot-swappable. When disconnecting power, first power down the storage system using the Dell Storage Client and then unplug the power cords from all the power supplies in the storage system. • Provide a suitable power source with electrical overload protection.
• Remove any jewelry or metal objects from your body because they are excellent metal conductors that can create short circuits and harm you if they come into contact with printed circuit boards or areas where power is present. • Do not lift a storage system chassis by the handles of the power supply units (PSUs). They are not designed to hold the weight of the entire chassis, and the chassis cover may become bent. • Before moving a storage system chassis, remove the PSUs to minimize weight.
After the storage system shuts down, unplug the power cables from the power supply/cooling fan modules. Replacing the Front Bezel The front bezel is a cover for the front panel of the storage system.
