About the SCv2080 Storage System
The SCv2080 storage system provides the central processing capabilities for the Storage Center
Operating System (OS) and management of RAID storage.
The SCv2080 storage system holds the physical disks that provide storage for the Storage Center. If
additional storage is needed, the SCv2080 also supports a single SC180 expansion enclosure.
SCv2080 Storage System Hardware
The SCv2080 is a 5U storage system that supports up to 84 3.5–inch hot-swappable SAS hard drives
installed in a two‐drawer, three‐row, 14‐column configuration.
The SCv2080 ships with two redundant power supply units, five redundant cooling fans, and up to two
redundant storage controllers. The storage controller contains multiple I/O ports that provide
communication with front-end servers and back-end storage.
SCv2080 Storage System Monitoring and Diagnostics
The Storage Center OS generates alert messages for temperature, I/O module, fan module, disk, and
power conditions for Storage Center components. Use the Dell Storage Client to view these alerts.
The SCv2080 also has LED indicators to notify you of a possible problem with the storage system.

Replacing SCv2080 Components
This section describes how to remove and install components of an SCv2080 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 SCv2080 storage
system in a rack.
• You need at least two people to lift the storage system chassis from the shipping box and three
people to install it in the rack. The empty chassis weighs approximately 62kg (137 lbs).
• 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.
• When loading a rack with chassis, fill from the bottom up; empty from the top down.
• To avoid danger of the rack toppling over, do not slide more than one chassis out of the rack at a
time.
• The storage system must be operated with low-pressure rear exhaust installation [back pressure
created by rack doors and obstacles not to exceed 5 Pascals (0.5 mm water gauge)].
• The rack design should take into consideration the maximum operating ambient temperature for the
unit, which is 35°C.
Replacing SCv2080 Components
19
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.
20
Replacing SCv2080 Components
• 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 SCv2080 storage
system.

Shutting Down a Storage Controller
If you are replacing a storage controller, use the Dell Storage Client to shut down the storage controller.
About this task
If the storage system has two storage controllers, shutting down one storage controller causes the
Storage Center to fail over to the other storage controller. which continues to process I/O. If the storage
system has only one storage controller, shutting it down results in a system outage.
