NOTE: Dell’s server and storage systems are certified as components for use in Dell’s
rack cabinet using the Dell customer rack kit. The final installation of Dell systems and
rack kits in any other brand of rack cabinet has not been approved by any safety agen-
cies. It is the customer’s responsibility to have the final combination of Dell systems
and rack kits for use in other brands of rack cabinets evaluated for suitability by a certi-
fied safety agency.
System rack kits are intended to be installed in a Dell rack by trained service tech-
nicians. If you install the kit in any other rack, be sure that the rack meets the
specifications of a Dell rack.
Do not move large racks by yourself. Due to the height and weight of the rack,
Dell recommends a minimum of two people to accomplish this task.
Before working on the rack, make sure that the stabilizers are secure to the rack,
extend to the floor, and that the full weight of the rack rests on the floor. Install
front and side stabilizers on a single rack or front stabilizers for joined multiple
racks before working on the rack.
Alwaysload the rackfromthebottomup, and loadtheheaviest itemintherackfirst.
Make sure that the rack is level and stable before extending a component from
the rack.
Extend only one component at a time from the rack.
Use caution when pressing the component rail release latches and sliding a com-
ponent into or out of a rack; the slide rails can pinch your fingers.
After a component is inserted into the rack, carefully extend the rail into a locking
position, and then slide the component into the rack.
Do not overload the AC supply branch circuit that provides power to the rack. The
total rack load should not exceed 80 percent of the branch circuit rating.

Dell PowerEdge 4350 System Upgrade Installation Guide 3
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any system/component when servicing other sys-
tems/components in a rack.

Static electricity can harm delicate components inside your computer. To prevent
static damage, discharge static electricity from your body before you touch any of
your computer’s electronic components, such as the processor. You can do so by
touching an unpainted metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal
surface to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
When unpacking a static-sensitive component from its shipping carton, do not
remove the component from the antistatic packing material until you are ready to
install the component in your computer. Just before unwrapping the antistatic
packaging, be sure to discharge static electricity from your body.
When transporting a sensitive component, first place it in an antistatic container
or packaging.
Handle all sensitive components in a static-safe area. If possible, use antistatic
floor pads and workbench pads.
The following notice may appear throughout this document to remind you of these
precautions:

1. Read the safety instructions in the previous section.
2. Provide for a suitable workspace that includes a place to unpack the upgrade kit,
a place to set the system while working on it, and a place to put the parts
removed from the system.
If an antistatic workbench pad is not available, be sure to follow all antistatic
precautions.
3. Verify the receipt and condition of all boxes and components.
4. Unpack the upgrade components.
5. Check and verify the physical condition of all upgrade components.
6. Verify that the system to be upgraded is a PowerEdge 4350 system.

1. Turn off your computer and any peripherals.
2. Ground yourself by touching
an unpainted metal surface on the chassis, such as
the metal around the card-slot openings at the back of the computer, before
touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer
chassis to dissipate any static electricity that might harm internal components.
3. Disconnect
your computer and peripherals from their power sources. Also, dis-
connect any telephone or telecommunication lines from the computer.
Doing so reduces the potential for personal injury or shock.

Dell PowerEdge 4350 System Upgrade Installation Guide 5
In addition, take note of these safety guidelines when appropriate:
When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. Some cables have a connector with locking tabs; if you are dis-
connecting this type of cable, press in on the locking tabs before disconnecting
the cable. As you pull connectors apart, keep them evenly aligned to avoid bend-
ing any connector pins. Also, before you connect a cable, make sure that both
connectors are correctly oriented and aligned.
Handle components and cards with care. Don’t touch the components or con-
tacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a
component such as a processor chip by its edges, not by its pins.
