Chapter 1 – Testing/Compatibility Information
1. Operating Condition Class
The operating condition class is A2. Based on the results of testing, it was determined that as long
as the server functions inside the Allowable Range as noted for “Operating Condition A2” (noted
in the table below), there will be no material affect to the system and will continue to operate as
intended for the entire lifecycle of the product.
The life expectancy of the server system is eight year on average. If the server runs for 18 hours a
day, seven days a week for eight years, the operating hours that the server can operate in the
allowable range for class A2 without becoming materially affected would be 52,560 hours.

Chapter 2 - Illustrated System Disassembly Instructions
Chapter 8 is intended to provide guidance to recyclers on the presence of materials and components at
the product/family level, per Article 15 of the EU WEEE Directive 2012/19/EU. The provided information
should also help direct recyclers to proper methods for removing parts and general product disassembly
instructions. This Chapter also outlines specific substances, mixtures, and components that must be
removed from any separately collected electronic waste component and shall be disposed or recovered
in compliance with Directive 2008/98/EC.
Please note: All the illustrations in the below disassembly instructions are for demonstration only. The
system and components shown in this section are a representative sample.
CAUTION: Always power off the system and unplug the power cord(s) first before disassembling the
system!

2. Data Storage Devices
Location: Servers are best known for their storage and interchangeability, within this tower
model of server there’s internal and external storage capacity. The internal storage is noted in the
diagram below. Some models may also include interchangeable storage that can be accessed
from the front panel. Some servers may also have SSD storage, this type of storage can be found
on the motherboard. It generally lays flat, parallel to the board, rather than at a right angle. Most
common applications insert one end of the SSD into a slot on the motherboard while the
alternate end is held in place with a small screw.
Type and number of fastenings: HDD = One (1) latch and four (6) Phillips screws, SSD = (1) Phillips
screw.
Tools required: Screwdriver with PH2 bit.
Procedure:
Step 1: HDD (3.5”) = Push the release button on the carrier. Swing the carrier perpendicular to
the chassis. Grasp the handle and pull the drive carrier out of its bay, once the drive carrier is out
of the bay, the Phillips screws can be removed.
Step 2: SSD (2.5”) = Identify the SSD on the motherboard, remove the screw, and pull straight
back in a parallel position to remove the SSD from the slot on the motherboard.
Selective Treatment/Special Handling Per Annex VII, Directive 2012/19/EU: There are two printed
circuit board present that are greater than 10 square centimeters, one within the HDD and one
within SSD that must be removed separately from the data storage device and shall be disposed
or recovered in compliance with Directive 2008/98/EC.
Step 1 Step 2

Chapter 3 – Installation, Maintenance and Replacement
Instructions
This chapter provides instructions on installing and replacing main system components. To prevent
compatibility issues, only use components that match the specifications and/or part numbers given.
Installation or replacement of most components require that the power first be removed from the
system. Please follow the procedures given in each section.
Additional information regarding replacement components/availability can be found in Chapter 5 below.
3.0 Removing Power
Use the following procedure to ensure that power has been removed from the system. This step is
necessary when removing or installing non hot-swap components or when replacing a non-redundant
power supply.
1. Use the operating system to power down the system.
2. After the system has completely shut-down, disconnect the AC power cord(s) from the power
strip or outlet.
3. Disconnect the power cord(s) from the power supply module(s).
