Document purpose
This installation guide provides instructions for installing the hardware associated with PowerProtect systems. Systems are
shipped to the customer site either pre-installed in a rack (factory-racked) or as separate components to install in an existing
rack at the site (field-installed). This guide provides instructions for both types of installation.
This document is intended for customers or Dell EMC Support personnel who are qualified to install PowerProtect systems.
Field-installed systems
To install PowerProtect systems in an existing rack at the customer site, follow all the instructions in this document to rack,
cable, and configure the system.
Factory-racked systems
Factory-racked systems are pre-installed in the rack with the cables already connected. Follow the instructions in Configure
System for Use on page 80 to configure factory-racked systems.
The following documents, available from the Online Support website, provide additional information about factory-racked
systems:

●Diagonal wire cutters (for cutting tie wraps)
●2 GB or greater USB flash memory drive
●Tie wraps (4 in. and 8 in.)
●(recommended) Roll of 5/8 inch Velcro cable tie material (3M Scotchmate SJ-3401 or similar)
Safety information
CAUTION:
●If the system is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
●The RJ45 sockets on the motherboard, PCI cards, or I/O modules are for Ethernet connection only and must
not be connected to a telecommunications network.
Review this list of important safety recommendations.
●All plug-in modules and blank plates are part of the fire enclosure and must be removed only when a replacement can be
added immediately. The system must not be run without all parts in place.
●A DD9800 system must be operated only from a power supply input voltage range of 200–240 VAC and 50–60 Hz. ES30
shelves use 100-240 VAC and 50–60 Hz. DS60 shelves use 200–240 VAC and 50–60 Hz.
●Each component is intended to operate with all working power supplies installed.
●Provide a suitable power source with electrical overload protection.
●A safe electrical earth connection must be provided to each power cord. Check the grounding of the power sources before
applying power.
●The plug on each power supply cord is used as the main device to disconnect power from the system. Ensure that the
socket outlets are located near the equipment and are easily accessible.
●Permanently unplug the unit if you think it is damaged in any way and before moving the system. A DD9800 system includes
four power supplies. To completely remove system power, you must disconnect all four power supplies.
●The power connections must always be disconnected prior to removal or replacement of a power supply module from any of
the components in the system.
●A faulty power supply module must be replaced within 24 hours.
●Do not lift system components by yourself. A DD9800 system weighs up to 117 lbs (53.2 kg), an ES30 expansion shelf
weighs up to 68 lbs (30.8 kg), and a DS60 shelf weighs up to 225 lbs (90.7 kg).
CAUTION: Data Domain systems are heavy. Use at least two people or a mechanical lift to move any system.
●Do not lift an expansion shelf by the handles on any modules. The handles are not designed to support the weight of the
populated shelf.
●To comply with applicable safety, emission, and thermal requirements, covers must not be removed and all bays must be
fitted with plug-in modules.
●Once removed from the shipping box, it is ok to lift the DD9800 system or the chassis with the four handles to place in a
rack. You will need to remove the handles from the sides before sliding the system in the rack. The four handles should be
saved for later use.
Introduction and Preparation 9

Figure 1. Warning about lifting the system
●Load the rack with storage shelves beginning at the bottom and the DD9800 system in the designated location to prevent
the rack from becoming top-heavy.
●For ESD protection, Data Domain recommends that you wear a suitable antistatic wrist or ankle strap. Observe all
conventional ESD precautions when handling plug-in modules and components.
●Do not extend components on slide rails until you have loaded at least three or more similarly weighted items in the rack, or
unless the rack is bolted to the floor or overhead structure to prevent tipping.
Working with a portable lift
If you are installing the shelf with all field replaceable units (FRUs) removed, you can install the shelf without using a lift. If you
need to install the shelf with FRUs onboard, use a portable lift.
Service personnel generally use the portable lift manufactured by Alum-A-Lift. Instructions for this lift are included in the lift kit.
http://www.corkc4.isus.emc.com/wiki/index.php/Lift_Tool describes the Lift equipment and the ordering process.
NOTE: If you are using a portable lift other than the Alum-A-Lift, adapt these instructions as necessary while following all
required safety requirements.
Lift requirements
For installations in racks that are 28U (49 inches) or less above the floor, use the lower mast, which is rated for 400 pounds.
For installations in racks that are more than 28U (49 inches) above the floor, use the lower mast configuration and a support
table with the "Voyager" conversion kit, which is rated for 225 pounds.
Adjusting the arms for a frontal lift
About this task
If you plan to use the mechanical lift directly in front of the cabinet, adjust the width of the lift arm/tray to just under 17 inches
to ensure that the arms will stay under the chassis.
Steps
1. Adjust the two arms with rollers so that they are 17 inches apart measured from the outside edges.
2. Tighten the arms to secure them.
The following figure shows an example of adjusting the lift arm/tray to just under 17 inches.

hole racks)
About this task
NOTE:
●Do not hold the bracket assembly in a vertical position as the parts may separate.
●If you are using a rack with threaded holes, skip this section and go to Install rail brackets using the adapter hardware
(for threaded hole racks) on page 17 section.
●The Data Domain system is 4 rack units (RU) tall so make sure the location in the rack fits the product. Attach the
bracket assembly to the lowest RU of the 4-RU opening.
●To comply with Data Domain rack mounting guidelines, the system controller should be installed in the pre-defined space
in the rack for system controllers. Refer to the Installation and Setup Guide for your system.
●For HA systems:
○Mount node 0 such that the bottom of the chassis aligns with the 13U mark in the rack.
○Mount node 1 such that the bottom of the chassis aligns with the 18U mark in the rack.
Steps
1.At each rack post, determine the vertical position in the rack where the brackets are to be installed. The top-most mounting
hole for a particular rack unit (RU) mounting position is typically identified by a mark or hole. The bracket will be installed in
the bottom hole of the 4 RU opening.
CAUTION: If the bracket is mounted in holes that are not vertically aligned from front to back, the bracket
may be damaged and mounting will not be secure.
2. As needed, select the bracket marked right or left. The rear of the bracket contains an adjustable piece.
3. From the rear of the system, hold the bracket against the inside of the rack posts. Align the rear guide pin and slide the

5. The rear of the chassis should engage with the tabs located in the rear of the rack mount kit.
6. At the front, attach the system to each installed bracket using the screws on the front of the system. The screws are shown
in red circles in the photo.
NOTE: On each side of the chassis, a bezel bracket sits between the upper and lower screws that secure the chassis to
the rack. The bezel brackets are marked with left and right to denote which side of the chassis to install them on.
However, the brackets for each side are not physically different. Inverting the bracket allows it to be used on the other
side of the chassis.
