Safety information
12 Data Domain DD9500 and DD9800 Systems 6.1 Hardware Overview and Installation Guide
l
If the system is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
l
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.
l
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.
l
A DD9500/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.
CAUTION
Planning and Site Preparation
l
Each component is intended to operate with all working power supplies installed.
l
Provide a suitable power source with electrical overload protection.
l
A safe electrical earth connection must be provided to each power cord. Check
the grounding of the power sources before applying power.
l
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.
l
Permanently unplug the unit if you think it is damaged in any way and before
moving the system. A DD9500/DD9800 system includes four power supplies. To
completely remove system power, you must disconnect all four power supplies.
l
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.
l
A faulty power supply module must be replaced within 24 hours.
l
Do not lift system components by yourself. A DD9500/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).
Data Domain systems are heavy. Use at least two people or a mechanical lift
to move any system.
l
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.
l
To comply with applicable safety, emission, and thermal requirements, covers
must not be removed and all bays must be fitted with plug-in modules.
l
Once removed from the shipping box, it is ok to lift the DD9500/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.
Figure 1
Warning about lifting the system
l
Load the rack with storage shelves beginning at the bottom and the DD9500
system in the designated location to prevent the rack from becoming top-heavy.
l
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.
Safety information 13
Planning and Site Preparation
l
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.

Hardware Overview
DD9500/DD9800 front panel
The four solid state drives (SSDs), the storage processor (SP), and the fans are
accessed from the front of the system. The SP must be pulled out to provide access
to the DIMMs. The fans are accessed without pulling or removing the SP and they are
hot-swappable. The photo shows the interfaces on the front of the system.
Figure 2 Front panel components
Front LED indicators
On the front panel to the right of SSD #4 (in Slot 3) are 3 LEDs that show high level
system status. The System Power LED glows blue to show the system is powered on.
The system can have power (be plugged in) but the blue LEDs are off if the system is
powered off.
The SP Service LED is normally off, but glows amber whenever the storage processor
(SP) requires service. The Enclosure Service LED is normally off, but glows amber
whenever the SP or other replaceable parts require service. The System Power and
Enclosure Service LEDs are visible through the front bezel.

Power supply units
Note
Hardware Overview
A DD9500/DD9800 system has four power supply units, numbered PSU0, PSU1,
PSU2, and PSU3 from left to right. Each power supply has its own integral cooling
fan.
The DD9500/DD9800 system should be powered from redundant AC sources. This
allows one AC source to fail or be serviced without impacting system operation. PSU0
and PSU1 should be attached to one AC source. PSU2 and PSU3 should be attached
to the other AC source.
The AC power plugs are located to the right of each power supply. The wire clips for
the AC cords hold the cords in place. The wire clips must be disengaged before
disconnecting the AC power to each power supply.

Ethernet I/O modules
A system can have up to a maximum of four Ethernet I/O modules of any type. The
four Ethernet I/O module limit applies to any combination of the different types of
Ethernet I/O modules. In other words two 10GBaseT and two fiber optic Ethernet I/O
modules are allowed. But three of each is not allowed. The available Ethernet I/O
modules are listed in the Available I/O modules on page 26.
Fibre Channel (FC) I/O modules
An FC I/O module is a dual-port Fibre Channel module. Up to four FC I/O modules
may be installed. The optional virtual tape library (VTL) feature requires at least one
FC I/O module. Boost over Fibre Channel is an optional feature and requires at least
one FC I/O module. A maximum of four FC I/O modules may be installed in a system
using either VTL or the Boost protocol or a combination of both protocols.
Hardware Overview
SAS I/O modules
DD9500/DD9800 systems have three quad-port SAS I/O modules installed in slots 2,
3 and 6. DD9500/DD9800 systems configured with DD Extended Retention (ER) or
DD Cloud Tier software options require an additional SAS I/O module in slot 9.
I/O module slot assignments
The following figure shows the location of the NVRAM and I/O modules.

2. I/O modules—slots 1 to 11 (See the I/O module slot assignments table.)
Slots 2, 3, and 6 (three I/O slots) are used for SAS I/O modules for systems without
Extended Retention (ER).
Slots 2, 3, 6, and 9 (four I/O slots) are for SAS I/O modules for systems with ER or
DD Cloud Tier software.
The table shows the I/O module slot assignments for the DD9500 and DD9800
systems. Each type of I/O module is restricted to certain slots.
The I/O module slot assignments for the DD9500 and DD9800 systems are the same.
