Systems management features
4
Overview: Dell commercial systems come with a number of systems management options that are include by default for In-Band
management with our Dell Client Command Suite. In-Band management meaning that the Operating System is functional and the device is
connected to a network so that it can be managed. The Dell Client Command Suite of tools can be leveraged individually or with a systems
management console like SCCM, LANDESK, KACE, etc.
We also oer Out-of-Band management as an option. Out-of-Band management is when the system does not have a functional operating
system or is turned o and you still want to be able to manage the system in that state.
In-Band Systems Management – Dell Client Command Suite
The Dell Client Command Suite of tools is free to download at http://dell.com/command and can be used with all OptiPlex desktops. It
contains the following components that can be used individually, or in the case of SCCM in conjunction with our integration for SCCM.
Dell Command | Deploy Driver Packs - Bundles of system specic drivers (web hosted on dell.com/command) that have been extracted
and reduced to an OS consumable state for use with any OS deployment tool. Here is a link to Dell TechCenter where you can nd the
driver packs for each commercial client system: http://en.community.dell.com/techcenter/enterprise-client/w/wiki/2065.dell-command-
deploy-driver-packs-forenterprise-client-os-deployment
Dell Command | Congure - A GUI based IT administrator tool for conguring and deploying hardware settings in either a pre-OS or post-
OS environment. Example congurations include enabling TPM, restricting access to USB ports, locking the BIOS with BIOS passwords,
disabling wireless/Bluetooth.
Dell Command | Monitor - A WMI (Windows Management Instrumentation) agent that provides deep hardware inventory and health
monitoring along with command line and scripting capabilities that allow IT administrators to congure their hardware remotely.
Dell Command | Update - a factory-installed application that end-users, with administrative rights, may utilize to individually manage their
own Dell updates. This tool leverages the Updates Catalog for scheduling and installing Dell updates (drivers, BIOS, rmware).
Technology and components 43
Page 44
Dell Command | Update Catalog - Provides searchable metadata that is leveraged with Dell Command | Update and enables management
consoles Dell KACE Appliances, LANDesk Management Systems and Microsoft System Center to retrieve the latest system specic
updates (driver, rmware, or BIOS) for any Dell commercial client to be delivered seamlessly to end-users.
Dell Command | PowerShell Provider - Furthers the ability to standardize on this industry-leading scripting preference by enabling IT
administrators to dynamically query and modify hardware settings with native PowerShell commands.
Dell Command | Power Manager - factory installed on all end-point devices with a battery (laptops, tablets) that enables modications
beyond the power options provided by the operating system.

USB features
Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplied the connection between host computers and peripheral
devices like mice, keyboards, external drivers, and printers.
Let's take a quick look on the USB evolution referencing to the table below.
Technology and components
46
Page 47
Table 4. USB evolution
Type Data Transfer Rate Category Introduction Year
USB 3.0/USB 3.1 Gen 2 5 Gbps Super Speed 2010
USB 2.0 480 Mbps High Speed 2000
USB 3.1 Gen 1 (SuperSpeed USB)
For years, the USB 2.0 has been rmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and
yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands. The USB 3.1 Gen 1 nally has
the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1 features are as
follows:
• Higher transfer rates (up to 5 Gbps)
• Increased maximum bus power and increased device current draw to better accommodate power-hungry devices
• New power management features
• Full-duplex data transfers and support for new transfer types
• Backward USB 2.0 compatibility
• New connectors and cable
The topics below cover some of the most commonly asked questions regarding USB 3.1 Gen 1.
Speed
Currently, there are 3 speed modes dened by the latest USB 3.1 Gen 1 specication. They are Super-Speed, Hi-Speed and Full-Speed. The
new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specication retains Hi-Speed, and Full-Speed USB mode, commonly
known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to maintain
backward compatibility.
USB 3.1 Gen 1 achieves the much higher performance by the technical changes below:
• An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).
• USB 2.0 previously had four wires (power, ground, and a pair for dierential data); USB 3.1 Gen 1 adds four more for two pairs of
dierential signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.
• USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold increase in
theoretical bandwidth.
Technology and components
47
Page 48
With today's ever increasing demands placed on data transfers with high-denition video content, terabyte storage devices, high megapixel
count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps
theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum. Similarly, USB 3.1
Gen 1 connections will never achieve 4.8Gbps. We will likely see a real-world maximum rate of 400MB/s with overheads. At this speed, USB
3.1 Gen 1 is a 10x improvement over USB 2.0.
Applications
USB 3.1 Gen 1 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB video was
barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine that with
5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps throughput.
Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will nd its way into some
products that previously weren't USB territory, like external RAID storage systems.
Listed below are some of the available SuperSpeed USB 3.1 Gen 1 products:
• External Desktop USB 3.1 Gen 1 Hard Drives
• Portable USB 3.1 Gen 1 Hard Drives
• USB 3.1 Gen 1 Drive Docks & Adapters
• USB 3.1 Gen 1 Flash Drives & Readers
• USB 3.1 Gen 1 Solid-state Drives
• USB 3.1 Gen 1 RAIDs
• Optical Media Drives
• Multimedia Devices
• Networking
• USB 3.1 Gen 1 Adapter Cards & Hubs
Compatibility
The good news is that USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all, while USB
3.1 Gen 1 species new physical connections and thus new cables to take advantage of the higher speed capability of the new protocol, the
connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as before. Five new
connections to carry receive and transmitted data independently are present on USB 3.1 Gen 1 cables and only come into contact when
connected to a proper SuperSpeed USB connection.
Windows 8/10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which
continue to require separate drivers for USB 3.1 Gen 1 controllers.
Technology and components
48
Page 49
Microsoft announced that Windows 7 would have USB 3.1 Gen 1 support, perhaps not on its immediate release, but in a subsequent Service
Pack or update. It is not out of the question to think that following a successful release of USB 3.1 Gen 1 support in Windows 7, SuperSpeed
support would trickle down to Vista. Microsoft has conrmed this by stating that most of their partners share the opinion that Vista should
also support USB 3.1 Gen 1.
Super-Speed support for Windows XP is unknown at this point. Given that XP is a seven-year-old operating system, the likelihood of this
happening is remote.
DDR4
DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512
GB in capacity, compared to the DDR3's maximum of 128 GB per DIMM. DDR4 synchronous dynamic random-access memory is keyed
dierently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the system.
DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4 also supports
a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deep power-down
mode is expected to reduce standby power consumption by 40 to 50 percent.
DDR4 Details
There are subtle dierences between DDR3 and DDR4 memory modules, as listed below.
Key notch dierence
The key notch on a DDR4 module is in a dierent location from the key notch on a DDR3 module. Both notches are on the insertion edge
but the notch location on the DDR4 is slightly dierent, to prevent the module from being installed into an incompatible board or platform.
Figure 1. Notch dierence
Increased thickness
DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.
Figure 2. Thickness dierence
Curved edge
DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.

Memory Errors
Memory errors on the system display the new ON-FLASH-FLASH or ON-FLASH-ON failure code. If all memory fails, the LCD does not
turn on. Troubleshoot for possible memory failure by trying known good memory modules in the memory connectors on the bottom of the
system or under the keyboard, as in some portable systems.
Active State Power Management
This section describes about the Active State Power Management (ASPM).
ASPM is the power management capability of hardware to eectively reduce usage of power by placing the PCI Express(PCIe) based
serial link devices to low-power state when not in use.
ASPM is controlled by BIOS or the power management component of the operating system in two congurations.
• Disabled: PCIe devices operate on high-performance mode.
• L1 Mode: Bi-directional setting of the serially linked PCIe device to low-power state.
NOTE
: This mode provides with higher power saving at expense of latency when re-establishing the connection.
The PCIe bus must be woken up from low-power mode to re-establish the connection with the device. This accounts for the latency, which
is also referred to as ASPM exit latency.

BIOS Update
You can run the BIOS update le from Windows using a bootable USB key or you can also update the BIOS from the F12 One-Time boot
menu on the system.
Most Dell systems built after 2012 have this capability and you can conrm by booting your system to the F12 One-Time Boot Menu to see
if BIOS FLASH UPDATE is listed as a boot option for your system. If the option is listed, then the BIOS supports this BIOS update option.
NOTE: Only systems with BIOS Flash Update option in the F12 One-Time Boot Menu can use this function.
Updating from the One-Time Boot Menu
To update your BIOS from the F12 One-Time boot menu, you will need:
• USB key formatted to the FAT32 le system (key does not have to be bootable)
• BIOS executable le that you downloaded from the Dell Support website and copied to the root of the USB key
• AC power adapter connected to the system
• Functional system battery to ash the BIOS
Perform the following steps to execute the BIOS update ash process from the F12 menu:
CAUTION: Do not power o the system during the BIOS update process. Powering o the system could make the system fail to
boot.

Enhanced Pre-Boot System Assessment — ePSA diagnostics
The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the
BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device
groups allowing you to:
• Run tests automatically or in an interactive mode
• Repeat tests
• Display or save test results
• Run thorough tests to introduce additional test options to provide extra information about the failed device(s)
• View status messages that inform you if tests are completed successfully
• View error messages that inform you of problems encountered during testing
You can invoke the ePSA diagnostics by tapping F12 key when the system posts and choose ePSA or Diagnostics option on One Time
Boot Menu.
CAUTION

NOTE: Some tests for specic devices require user interaction. Always ensure that you are present at the computer terminal
when the diagnostic tests are performed.
NOTE: Regular ePSA’s run for about 5 to 10 minutes, however, the extended test takes about three and half hours with only 8GB
of ram in the system.
: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid
