Replacing SCv2000/SCv2020 Components
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. For your safety and protection, observe the rules described
in the following sections.
NOTE: See the safety and regulatory information that shipped with each Storage Center
component. Warranty information may be included within this document or as a separate
document.
Installation Safety Precautions
Follow these safety precautions:
• Dell recommends that only individuals with rack-mounting experience install an SCv2000/SCv2020
storage system in a rack.
• Make sure the storage system is fully grounded at all times to prevent damage from electrostatic
discharge.
• When handling the storage system hardware, you should use an electrostatic wrist guard (not
included) or a similar form of protection.
The storage system chassis MUST be mounted in a rack; the following safety requirements must be
considered when doing so:
• The rack construction must be capable of supporting the total weight of the installed chassis and the
design should incorporate stabilizing features suitable to prevent the rack tipping or being pushed
over during installation or in normal use.
• To avoid danger of the rack toppling over, do not slide more than one chassis out of the rack at a
time.
• The rack design should take into consideration the maximum operating ambient temperature for the
unit, which is 57°C.

Page 18
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. All Storage Center components
must be grounded before applying power. Make sure that there is a safe electrical earth connection to
power supply cords. Check the grounding before applying power.
• The plugs on the power supply cords are used as the main disconnect device. Make sure that the
socket outlets are located near the equipment and are easily accessible.
• Know the locations of the equipment power switches and the room's emergency power-off switch,
disconnection switch, or electrical outlet.
• Do not work alone when working with high-voltage components.
• Use rubber mats specifically designed as electrical insulators.
• Do not remove covers from the power supply unit. Disconnect the power connection before
removing a power supply from the storage system.
• Do not remove a faulty power supply unless you have a replacement model of the correct type ready
for insertion. A faulty power supply must be replaced with a fully operational module power supply
within 24 hours.
• Unplug the storage system chassis before you move it or if you think it has become damaged in any
way. When powered by multiple AC sources, disconnect all supply power for complete isolation.
Electrostatic Discharge Precautions
Always follow electrostatic discharge (ESD) precautions to avoid injury and damage to Storage Center
equipment.
Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into
contact with each other. The resulting electrical discharge can damage electronic components and
printed circuit boards. Follow these guidelines to protect your equipment from ESD:
• Dell recommends that you always use a static mat and static strap while working on components in
the interior of the storage system chassis.
• Observe all conventional ESD precautions when handling plug-in modules and components.
• Use a suitable ESD wrist or ankle strap.
• Avoid contact with backplane components and module connectors.
• Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use.
General Safety Precautions
Always follow general safety precautions to avoid injury and damage to Storage Center equipment.
• Keep the area around the storage system chassis clean and free of clutter.
• Place any system components that have been removed away from the storage system chassis or on a
table so that they are not in the way of foot traffic.
• While working on the storage system chassis, do not wear loose clothing such as neckties and
unbuttoned shirt sleeves, which can come into contact with electrical circuits or be pulled into a
cooling fan.
18
Replacing SCv2000/SCv2020 Components
Page 19
• 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.
• Do not remove drives until you are ready to replace them.
NOTE: To ensure proper storage system cooling, hard drive blanks must be installed in any hard
drive slot that is not occupied.
Pre-Replacement Procedures
Perform the procedures described in this section before replacing a component of an SCv2000/SCv2020
storage system.
