Safety Warnings
Heed safety instructions: Before working with your server product, whether you are using this guide or any
other resource as a reference, pay close attention to the safety instructions. You must adhere to the
assembly instructions in this guide to ensure and maintain compliance with existing product certifications
and approvals. Use only the described, regulated components specified in this guide. Use of other
products/components will void the UL listing and other regulatory approvals of the product and will most
likely result in noncompliance with product regulations in one or more regions in which the product is sold.
System power on/off: The power button DOES NOT turn off the system AC power. To remove power from
the system, you must unplug the AC power cord. Make sure the AC power cord is unplugged before you
open the chassis, add, or remove any components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power,
telephone, and communication cables. Turn off the server and disconnect the power cord,
telecommunications systems, networks, and modems attached to the server before opening it. Otherwise,
personal injury or equipment damage can result.
Installing or removing jumpers: A jumper is a small plastic encased conductor that slips over two jumper
pins. Some jumpers have a small tab on top that you can grip with your fingertips or with a pair of fine needle
nosed pliers. If your jumpers do not have such a tab, take care when using needle nosed pliers to remove or
install a jumper; grip the narrow sides of the jumper with the pliers, never the wide sides. Gripping the wide
sides can damage the contacts inside the jumper, causing intermittent problems with the function controlled
by that jumper. Take care to grip with, but not squeeze, the pliers or other tool you use to remove a jumper,
or you may bend or break the pins on the board.
Electrostatic Discharge (ESD)
Electrostatic discharge can damage the computer or the components within it. ESD can occur without the
user feeling a shock while working inside the system chassis or while improperly handling electronic devices
like processors, memory or other storage devices, and add-in cards.
Intel recommends the following steps be taken when performing any procedures described within this
document or while performing service to any computer system.
•Where available, all system integration and/or service should be performed at a properly equipped
ESD workstation
•Wear ESD protective gear like a grounded antistatic wrist strap, sole grounders, and/or conductive
shoes
•Wear an anti-static smock or gown to cover any clothing that may generate an electrostatic charge
•Remove all jewelry
•Disconnect all power cables and cords attached to the server before performing any integration or
service
•Touch any unpainted metal surface of the chassis before performing any integration or service
•Hold all circuit boards and other electronic components by their edges only
•After removing electronic devices from the system or from their protective packaging, place them
component side up on to a grounded anti-static surface or conductive workbench pad. Do not place
electronic devices on to the outside of any protective packaging.

Caution: Slide / Rail mounted equipment is not to be used as a shelf or a workspace
Intel warranties that this product will perform to its published specifications. However, all computer systems
are inherently subject to unpredictable system behavior under various environmental and other conditions.
This product is not intended to be the sole source for any critical data and the user must maintain a verified
backup. Failure to do so or to comply with other user notices in the product user guide and specification
documents may result in loss of or access to data.
Weight of the system:
•Due to the weight of a system, Intel recommends carrying the system with two people supporting the
system from the sides or using a mechanical lift or a cart when moving the system from one location
to another.
•If your system has rack handles installed, do not lift or carry the system by the rack handles
•When lifting or moving a chassis, always grasp it by all four corners. Do not grasp the chassis by two
points at opposing diagonal corners, doing so may damage the internal components.
•If you can only grasp the chassis at two different points, always grasp the chassis by the sides at the
midpoint.

2. System Access and Cable Routing
Most procedures documented in the following chapters will require access to the inside of the system. This
chapter provides step-by-step instructions for the removal and reinstallation of both the system top cover
and the system air duct.
In addition, as this server family can support many different system configurations where several internal
cables may be necessary, this chapter will provide guidance for best cable routing using features designed
into the chassis.
Before You Begin
Before integration of any system components, review all the safety and ESD precautions found in the Safety
Warnings section at the beginning of this document.
System Reference
In the following procedures, all references to left, right, front, top, and bottom assume the reader is facing
the front of the server chassis.
Instruction Format
Each procedure described in this chapter follows an illustration first format. This format gives the reader the
option to follow a quicker path to completing the objective by first seeing an illustration of the intended
procedural step or steps. If necessary, the reader can follow the step-by-step instructions that follow each
illustration.
