Description
Quick Resource Locator (QRL)
This code on the chassis can be scanned by a smartphone application to
access additional information and resources for the server, including
videos, reference materials, service tag information, and Dell contact
information.
The T620 has two versions of the front panel depending on the orientation of the system. The front
control panel for a tower server has an LCD, which is an iDRAC-controlled graphics display that
provides system information through error codes.
The front control panel for a rack server has a VGA port to support a monitor.
A useful feature included with Dell PowerEdge 12th generation servers is the Quick Resource Locator
(QRL)—a model-specific Quick Response (QR) code that is located inside the T620 chassis cover
(see Figure 8). Use your smartphone to access the Dell QRL app to learn more about the server.
This QRL code allows you to:
View step-by-step videos, including overviews of system internals and externals, as well as
detailed, concise, task-oriented videos and installation wizards

Locate reference materials, including searchable owner’s manual content, LCD diagnostics, and
an electrical overview
Look up your service tag so you can quickly gain access to your specific hardware configuration
info and warranty information
Contact Dell directly (by link) to get in touch with technical support and sales teams and provide
feedback to Dell
These codes provide an easy way to retrieve the critical support information you need when you
need it, making you more efficient and effective in managing your hardware.
The PowerEdge servers have the features listed in Table 5 to help ensure the security of your data
center.
Security feature
Description
Cover latch
A tooled latch is integrated in the side cover to secure it to the rack chassis.
Front bezel
An optional metal bezel is mounted to the chassis front to provide the Dell ID. A
lock on the bezel protects un-authorized access to the hard drives and optical
drive. Although the bezel has an open area to allow access to the tape backup in
bay 2, the rest of the system remains locked. System status is viewable on the
LCD screen when the bezel is installed.
TPM
The Trusted Platform Module (TPM) is used to generate/store keys,
protect/authenticate passwords, and create/store digital certificates. It also
supports the Intel Xeon TXT functionality. TPM can also be used to enable the
BitLocker™ hard drive encryption feature in Windows Server 2008. TPM 1.2 is
supported. No TPM version is available for China or Russia.
Power-off security
BIOS has the ability to disable the power button function.
Intrusion alert
An internal switch is used to detect chassis intrusion.
Secure mode
BIOS has the ability to enter a secure boot mode through system setup. This
mode includes the option to lock out the power and NMI switches on the
control panel or set up a system password.

The Dell PowerEdge T620 features the Intel Xeon processor E5-2600 product family, which offers
an ideal combination of performance, power efficiency, and cost. These processors provide high
performance no matter what your constraint is—floor space, power, or budget—and on workloads
that range from the most complicated scientific exploration to crucial web-serving and
infrastructure applications. In addition to providing raw performance gains, improved I/O is also
made possible with Intel Integrated I/O, which can reduce latency by adding more lanes and
doubling bandwidth. This helps to reduce network and storage bottlenecks, unleashing the
processor’s performance capabilities.
The new Intel Xeon processor E5-2600 product family not only adds new features, but also
improves upon many features of the predecessor Intel Xeon processor 5600 series, including:
Up to two additional cores and up to 8MB more last level cache
More memory—six additional DIMMs and support for up to 32GB DIMMs, which increases
memory capacity from 288GB to 768GB
Intel Integrated I/O has support for up to 80 lanes of PCIe 3.0, which can reduce latency
Faster connections are provided throughout the system with support for DDR3 1600MT/s
memory and 8.0GT/s QPI
Intel Data Direct I/O (DDIO) allows I/O traffic to skip the main system memory and be directed
straight to the processor cache, which can provide a significant reduction in latency as well as
allowing memory to remain in a low-power state
Intel Advanced Vector Extensions offer up to double the floating point operations per clock cycle
by doubling the length of registers, which can be useful for addressing very complex problems or
dealing with large-number calculations, which are integral to many technical, financial, and
scientific computing problems
Intel Turbo Boost Technology 2.0 delivers up to double the boost than the
previous-generation turbo technology
Continued improvements to both Intel TXT and AES-NI help to better protect systems and data

GPU cards are installed in the PCIe x16 2.0 interfaces, which are slots 2, 4, 5 and 7; slots 5 and 7 only
work with two processors.
Note: You must select the GPU enablement kit at point of sale to install GPU or keep the system's
GPGPU capability. GPU enablement kit is not upgradable after point of sales.
With one processor installed, two GPU cards are supported with the following restrictions:
Slots 1, 2, 3, and 4 are available, therefore only two GPUs can be installed in slots 2 and 4
Since double-wide GPU cards occupy two slots, only two can be installed and slots 1 and 3 are
not available
RAID cards cannot be installed with two double-wide GPU cards
With single-wide GPU cards, the PERC H710, H710P, or H810 cannot occupy slots 1 or 3 (PERC
cards have batteries that would overheat if located beside a GPU card)
With two processors installed, four GPU cards are supported, with the restrictions:
Slots 2, 4, 5, and 7 are available
Since double-wide GPU cards occupy two slots, slots 1, 3, and 6 are not available
RAID cards cannot be installed with four double-wide GPU cards
With single-wide GPU cards, the PERC H710, H710P, or H810 cannot occupy slots 1, 3, or 6
(PERCs have batteries that would overheat if located beside a GPU card)
With PCIe SSDs, two GPU cards can occupy slots 5 and 7. Slot 2 is for a PCIe SSD expender card and
slot 4 cannot support a GPU card because of thermal restrictions.
Some operating systems have not been validated to support GPUs. See Table 23 and Table 24 for
more information on operating system support of GPUs.
The Intel C600 chipset is implemented on the PowerEdge T620. For more information, visit
Intel.com.

More memory options are available than ever before with the Dell PowerEdge T620—greater
capacities, higher frequencies, and more flexibility. The T620 supports up to 768GB of memory
(24 DIMMs) and speeds up to 1600 MT/s, providing high performance in a variety of applications.
High memory density means there is no compromise when it comes to virtualization.
Increase your uptime and reduce data loss due to Dell’s focus on reliability, availability, and
serviceability (RAS) features. RAS aids in the rapid and accurate diagnosis of faults which require
service, increasing your memory reliability. System uptime is reinforced with RAS features like
memory mirroring, sparing, and many others.
In addition to supporting existing unbuffered DIMMs (UDIMMs) and registered DIMMs (RDIMMs), the
T620 supports load reduced DIMMs (LRDIMMs), which use a buffer to reduce memory loading and
provide greater density, allowing for the maximum platform memory capacity.
