3 Routine care, SATA drive guidelines, and
disassembly preparation
This information provides general service information for the computer. Adherence to the procedures and
precautions is essential for proper service.
IMPORTANT: When the computer is plugged into an AC power source, voltage is always applied to the system
board. You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.
ENWW 11
Electrostatic discharge information
A sudden discharge of static electricity from your nger or other conductor can destroy static-sensitive devices
or microcircuitry. Often the spark is neither felt nor heard, but damage occurs.
An electronic device exposed to electrostatic discharge (ESD) might not appear to be aected at all and can work
perfectly throughout a normal cycle. The device might function normally for a while, but it has been degraded in
the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains
enough power to alter device parameters or melt silicon junctions.
IMPORTANT: To prevent damage to the device when you are removing or installing internal components,
observe these precautions:
Keep components in their electrostatic-safe containers until you are ready to install them.
Before touching an electronic component, discharge static electricity by using the guidelines described in this
section.
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
If you remove a component, place it in an electrostatic-safe container.
Generating static electricity
This table shows how humidity aects the electrostatic voltage levels generated by dierent activities. A product
can be degraded by 700 V.
● Dierent activities generate dierent amounts of static electricity.
● Static electricity increases as humidity decreases.

Preventing electrostatic damage to equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of
sensitivity. The following packaging and grounding precautions are necessary to prevent static electricity
damage to electronic components.
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
● Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
● Place items on a grounded surface before removing them from their container.
● Always be properly grounded when touching a sensitive component or assembly.
● Avoid contact with pins, leads, or circuitry.
● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam.
Personal grounding methods and equipment
Use this equipment to prevent static electricity damage to electronic components.
● Wrist straps are exible straps with a maximum of 1 MΩ ±10% resistance in the ground cords. To provide
proper ground, a strap must be worn snug against bare skin. The ground cord must be connected and t
snugly into the banana plug connector on the grounding mat or workstation.
● Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with most
types of shoes or boots. On conductive oors or dissipative oor mats, use them on both feet with a
maximum of 1 MΩ ±10% resistance between the operator and ground.

The memory sockets on the system board are populated with at least one preinstalled memory module. To
achieve the maximum memory support, you can populate the system board with up to 128 GB of memory
congured in a high-performing dual-channel mode.
For proper system operation, the DIMMs must adhere to the following specications:
● Industry-standard 288-pin
● Unbuered non-ECC PC4-19200 DDR4-2400/2666 MHz-compliant
ENWW Memory modules (DIMMs) 25
● 1.2 V DDR4-SDRAM memory modules
● CAS latency 17 DDR4 2400/2666 MHz (17-17-17 timing)
● Mandatory JEDEC SPD information
The computer supports the following setups:
● 512 Mbit, 1 Gbit, 2 Gbit, and 4 Gbit non-ECC memory technologies
● Single-sided and double-sided memory modules
● Memory modules constructed with ×8 and ×16 DDR devices; memory modules constructed with ×4 SDRAM
are not supported
NOTE: The system does not operate properly if you install unsupported memory modules.
There are four memory sockets on the system board, with two sockets per channel. The sockets are labeled
DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3
and DIMM4 operate in memory channel A.
The system automatically operates in single-channel mode, dual-channel mode, or ex mode, depending on
how the DIMMs are installed.
NOTE: Single-channel and unbalanced dual-channel memory congurations results in inferior graphics
performance.
● The system operates in single-channel mode if the DIMM sockets are populated in one channel only.
● The system will operate in a higher-performing dual-channel mode if the total memory capacity of the
DIMMs in channel A is equal to the total memory capacity of the DIMMs in channel B. The technology and
device width can vary between the channels. For example, if channel A is populated with two 1 GB DIMMs
and channel B is populated with one 2 GB DIMM, the system will operate in dual-channel mode.
● The system operates in ex mode if the total memory capacity of the DIMMs in channel A is not equal to
the total memory capacity of the DIMMs in channel B. In ex mode, the channel populated with the least
amount of memory describes the total amount of memory assigned to dual channel and the remainder is
assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount
of memory is spread between the two channels. If one channel will have more memory than the other, the
larger amount should be assigned to channel A. For example, if you are populating the sockets with one 2
GB DIMM, and three 1 GB DIMMs, channel A should be populated with the 2 GB DIMM and one 1 GB DIMM,
and channel B should be populated with the other two 1 GB DIMMs. With this conguration, 4 GB runs as
dual channel and 1 GB will run as single channel.
● In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
26 Chapter 4 Removal and replacement procedures ENWW
IMPORTANT: You must disconnect the power cord and wait approximately 30 seconds for the power to drain
before adding or removing memory modules. Regardless of the power state, voltage is always supplied to the
memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory
modules while voltage is present can cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to
use memory modules with gold-plated metal contacts to prevent corrosion, oxidation, or both resulting from
having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning
these procedures, be sure that you are discharged of static electricity by briey touching a grounded metal
object. For more information, see
When handling a memory module, be careful not to touch any of the contacts. Doing so can damage the module.

the MBR, the data on the disk might become inaccessible. Only restore a previously saved MBR if you
are condent that the current bootable disk's MBR has been corrupted or infected with a virus.
● Save/Restore GPT of System Hard Drive
Enabling this feature saves the GUID Partition Table (GPT) of the system hard drive. If the GPT is
subsequently changed, the user is prompted to choose whether to restore GPT.
● DriveLock/Automatic DriveLock
Allows you to assign or modify a master or user password for hard drives. When this feature is enabled,
the user is prompted to provide one of the DriveLock passwords during POST. If neither is successfully
entered, the hard drive remains inaccessible until one of the passwords is successfully provided during
a subsequent cold-boot sequence.
NOTE: This selection appears only when at least one drive that supports the DriveLock feature is
attached to the system.
IMPORTANT: Be aware that these settings take place immediately. It is not necessary to save.
IMPORTANT: Be sure to document the DriveLock password. Losing a DriveLock password will render a
drive permanently locked.
After you select a drive, the following options are available:
- Set DriveLock Master Password. Sets the drive’s master password but does not enable DriveLock.
- Enable DriveLock. Sets the drive’s user password and enables DriveLock.

● Legacy Boot Order
Specify the order in which legacy boot sources (such as a network interface card, internal hard drive,
USB optical drive, or internal optical drive) are checked for a bootable operating system image.
Specify the order of attached hard drives. The rst hard drive in the order will have priority in the boot
sequence and will be recognized as drive C (if any devices are attached).
NOTE: To drag a device to a preferred place, press enter.
