FE Toolkit Inventory and Common Procedures for FRU Tasks
This document describes the tools required to perform the tasks described in Data Domain FRU
documents. This document also explains how to connect to a Data Domain system and run DD OS
commands with a laptop computer and terminal emulator.
The audience for this document is a Field Engineer preparing to perform a FRU task for a Data Domain
system or storage shelf.
Toolkit Inventory
Laptop Computer and Software
Use a laptop computer as a terminal to log into the system and run DD OS commands. For help
connecting, see “Connecting to the System with a Terminal Emulator”.
The recommended terminal emulation program is SecureCRT®, configured with a 5,000 line or larger
buffer. Any version of SecureCRT is suitable. If SecureCRT is not available, use PuTTY version 0.58 or
later. Windows Hyperterminal is not recommended.
Tools, Cables, and Supplies
FRU procedures for Data Domain systems and storage shelves may require the following tools and
supplies:
• Null modem cable (DB-9 female to female), plus spare
• USB-to-DB-9 serial (male connector) converter cable if the laptop does not have a serial port, plus
spare
• Power adapter, C13 to NEMA 5-15 (if based in North America), or a power cord for your laptop power
adapter with a C13 plug, so that you can power your laptop from a rack PDU
• Antistatic wrist strap and conductive foam pad
• Screwdrivers:
• Phillips #2 with a 12 inch or longer blade
• Phillips #2 (standard-length blade)
• Phillips #1
• Flat head 3/16 inch
• Flat head 1/4 inch
• Torx T10
• Flashlight
• Needle nose pliers
• Diagonal wire cutters (for cutting tie wraps)
• 2 GB USB flash memory drive
• Tie wraps (4 inch and 8 inch)
• (recommended) Roll of 5/8 inch Velcro cable tie material (3M Scotchmate SJ-3401 or similar)
Connecting to the System with a Terminal Emulator
To connect to a Data Domain system and run DD OS commands:
1. [ ] Connect a serial cable between your laptop and the Data Domain system. If necessary, also use
a USB-to-DB-9 converter cable to connect the serial cable to your laptop.
Dell Technologies – Customer’s Internal Use Only – Confidential \& Subject to NDA

3. [ ] Enable logging of the session.
4. [ ] Log in to the system.
5. [ ] Default login information:
a. User: sysadmin
b. Password: [Unit Serial Number]
Failed Part Identification
CAUTION: Prior to starting any parts replacement, the failed part must be positively identified. This is
particularly important with components for external storage shelves. Shelf numbering may change between
system reboots on some DDOS versions. In later versions of DDOS shelf numbering is persistent but shelf
renumbering can be manually initiated, and the renumbering occurs at the next reboot.
The failed part must be positively identified and the physical location verified so that the proper part is
replaced. Various methods for identification exist and will vary with the part.
In most cases identification of the failed part will require access to either CLI or GUI access to the Data
Domain system. This may require customer assistance to gain access to the DD system CLI or GUI.

DD4500 Safety Instructions
Management and IO Modules
CAUTION: This procedure does not describe the replacement of the NVRAM-BBU combination module.
See the EMC Data Domain DD4200, DD4500, and DD7200 NVRAM and BBU Replacement Guide.
The eleven IO module positions, as seen from the back panel, are slotted in the chassis as shown in
Figure 1 on page 3. An LED on the front of each IO module displays its status. The NVRAM-BBU
combination module is located in slots 9 and 10. The management module is located in slot Mgmt A on
the far left of the rear panel.
The management module provides an RJ-45 LAN port for management access to the SP module.

Slot Addition Rules
When a system is upgraded by installing additional IO module(s), the additional IO module(s) should be
populated as follows:
• A maximum of six optional IO modules (FC plus Ethernet) are allowed in systems without Extended
Retention software, and a maximum of five optional IO modules (FC plus Ethernet) are allowed in
systems with Extended Retention software.
Dell Technologies – Customer’s Internal Use Only – Confidential \& Subject to NDA
Page 7 of 17

• Additional FC module(s) should be installed in numerically increasing slot numbers immediately to the
right of the existing FC modules, or starting in slot 0 if no FC modules were originally installed. A
maximum of four FC modules are allowed in a system.
• uAdditional Ethernet modules should be installed in numerically decreasing slot numbers immediately
to the left of the existing Ethernet modules or starting in slot 4 if no Ethernet modules were originally
installed. For systems without Extended Retention software, a maximum of six (limited to four of any
one type) Ethernet modules can be present. For systems with Extended Retention software, a
maximum of five (limited to four of any one type) Ethernet modules can be present.
• All systems include two SAS modules in slots 7 and 8. Systems with Extended Retention software
must have two additional SAS modules in slots 5 and 6.
• For systems without Extended Retention software, if adding IO modules results in the allowed
maximum of six IO modules present, slot 5 will also be used. Slot 5 should only be used for an
Ethernet module. Adding FC modules in this specific case will require moving an existing Ethernet
module to slot 5. Other than this specific case, it is not recommended to move IO modules between
slots.
• Adding Extended Retention software to a system involves adding two SAS modules in slots 5 and 6.
If the system originally had the maximum of 6 optional IO modules, the IO module in slot 5 must be
permanently removed from the system.
See the following sections for additional information about preparing to upgrade systems with additional
Ethernet, SAS, or FC IO modules:
• Preparing to Install Ethernet IO Modules on page 5
• Preparing to Install Fibre Channel (FC) IO Modules on page 5
• Preparing to Install SAS IO Modules on page 6
Preparing to Install Ethernet IO Modules
A system can have a total of up to six Ethernet IO modules, where no more than four of any one IO
module is used.
The available Ethernet IO modules are:
• Dual Port 10GBase-SR Optical with LC connectors
• Dual Port 10GBase-CX1 Direct Attach Copper with SPF+ module
• Quad Port 1000Base-T Copper with RJ-45 connectors
• Quad Port 2 port 1000Base-T Copper (RJ45) / 2 Port 1000Base-SR Optical
See the “Managing Network Connections” chapter in the EMC Data Domain Operating System
Administration Guide for help configuring any Ethernet interface.
Preparing to Install Fibre Channel (FC) IO Modules
An FC IO module is a dual-port Fibre Channel module. Up to four FC IO modules may be installed. The
optional virtual tape library (VTL) feature requires at least one FC IO module. Boost over Fibre Channel is
optional and the total FC HBAs cannot exceed more than allowable Fibre Channel cards per controller.
The dual-port FC IO module is necessary when implementing the VTL protocol, and can also be used
with the DD Boost protocol. A maximum of four FC IO modules may be installed in a system, using either
protocol or a combination of both protocols, as described in the following sections.
Add a VTL license
Before you begin
The Virtual Tape Library (VTL) feature is enabled through a software license. Two types of VTL licenses
are available. Depending on the implementation, either one or both license keys will be needed. For Open
Systems VTL (including Windows support) the standard VTL license is needed. IBM i environments
Dell Technologies – Customer’s Internal Use Only – Confidential \& Subject to NDA
Page 8 of 17

require the IBM i license. If the system requires VTL emulation for both Open Systems and IBM i
environments, both licenses will need to be enabled.
Procedure
1. [ ] If VTL is a new feature for your system, log in as an administrative user and enter the following
command to add the license key to the system. Licenses can also be added using the DD System
Manager GUI.
# license add license-key
After you finish
For help connecting to a system using a laptop computer and terminal emulator, see the document FE
Toolkit Inventory and Common Procedures for FRU Tasks at https://my.datadomain.com/documentation.
Add DD Boost over Fibre Channel license
Before you begin
Beginning with DD OS release 5.3, the DD Boost protocol is supported with Fibre Channel (in addition to
Ethernet). Only one DD Boost license is required per system, which can be used with Ethernet or Fibre
Channel.
Procedure
1. [ ] If DD Boost is a new feature for your system, log in as an administrator and enter the following
command to add the license key to the system. Licenses can also be added using the DD System
Manager GUI.
# license add license-key
2. [ ] If a DD Boost license is already enabled on the system, you do not need to add an additional
license key to implement DD Boost over Fiber Channel. If the DD Boost license and an FC IO module
have both been installed, then the DD Boost over Fibre Channel feature is available but still needs to
be enabled. Please refer to the DD OS Administration Guide for how to enable license features.
After you finish
For help connecting to a system using a laptop computer and terminal emulator, see the document FE
Toolkit Inventory and Common Procedures for FRU Tasks at https://my.datadomain.com/documentation.
Preparing to Install SAS IO Modules
DD4200, DD4500, and DD7200 systems have two quad-port SAS IO modules in slots 7 and 8. DD4200,
DD4500, and DD7200 systems configured with DD Extended Retention software option require two
additional SAS IO modules in slots 5 and 6.
Remove and Install an IO Module
The following instructions describe how to remove and install the management module or IO modules.
Note: These instructions do not cover the removal of an NVRAM-BBU combination module. See DD4200,
DD4500, and DD7200 NVRAM and BBU Module Replacement Guide for the procedure to replace a BBU
or NVRAM module.
CAUTION:
IO modules are not hot swappable. The system must be powered down.
Only trained and qualified personnel should be allowed to install or replace this equipment.
During the procedure, wear a grounding wrist strap to avoid ESD damage to the equipment.

Testing SAS Cabling \& Ports
Data Domain appliances have a command, enclosure test topology, that tests the integrity of the
connectivity between all SAS connected elements (the appliance and all shelves). This command
generates and passes I/O traffic, which will help determine if there are physical cabling issues or
hardware issues with SAS cards. This command should be run on any system utilizing DDOS 4.7.4 or
later.
Before leaving the customer location, at the end of the installation, follow these steps:
• Run the enclosure show topology command to note and verify attached storage connections.
•Reseat the cables if a problem is indicated.
• Run the enclosure test topology command for 5 minutes for each card, in the example below
that would be 3a and 4a.
•If the results show a good connection the unit can be turned over to the customer
•If the results indicate a problem, recable \ reseat the affected link(s) and rerun the command
• If the problem persists, please contact support for further diagnosis and potentially parts dispatch
