Chapter 1 - European Union (EU) Ecodesign Requirements
This chapter addresses European Union (EU) Ecodesign requirements for servers and storage products.
All data and ratings within this addendum are in reference only to the Ace Computers product(s) in the
manual. The below information conforms to requirements laid down in Annex II of the Commission
Regulation 2019/424.
3(1)(a): See Section 1.1 of the system manual for the product type.
3(1)(b): See the title page and preface of the system manual for the trademark and
manufacturer’s address.
3(1)(c): See the title page of the system manual for product model number(s).
3(1)(d): See the serial number on the physical system to determine the year of manufacture.
3(1)(e-j): PSU Efficiency and Power Factor Value (Table) (From 80 Plus report)

ACE088 Page 6 of 21 Rev Date: 9.21.2021
3(1)(k): 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 24 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 70,080 hours.
3(1)(l): The idle state power at the higher boundary temperature of the operating conditions
class is 331.9W.
3(1)(m): The active state efficiency and performance is 26.0.
3(1)(n): There are two methods by which a user can securely delete data from this system. The
user performing secure data deletion should be an IT professional.
The first is with a Unified Extensible Firmware Interface (UEFI) shell utility. This utility
works on X10/X11/H11/H12/M11 motherboard series with onboard SATA/NVMe
devices. Any user may access and download this utility through our trusted third party
vendor, following link:
https://www.supermicro.com/about/policies/disclaimer.cfm?url=/wftp/utility/Lot9_Sec
ure _Data_Deletion_Utility/
Download the shell utility package and extract it to a USB flash drive, then plug the drive
into the server for which secure data deletion is necessary. Then turn the system on.
Navigate to the BIOS setup menu, then place the server system into the UEFI shell
environment. Follow the instructions in the README file to invoke the utility and
complete the deletion.

ACE088 Page 7 of 21 Rev Date: 9.21.2021
The second method is through the secure data deletion tool provided by the original
manufacturer of the hard drive. This should be used in a scenario where the shell utility
is not applicable. Each manufacturer should have the tool available on their website. If
needed, please look on the hard drive label for the name of the manufacturer and
model information.
3(1)(o): List of recommended combinations of blade servers with chassis: N/A.
3(1)(p): List of all current SKUs within this product family.

1. Data Storage Devices
Location: Servers are best known for their storage and interchangeability, this is most commonly
done through front hard drive bays as noted in the photo below. 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:
HDD = Push the release button on the carrier. Swing the handle fully. 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.
SSD = 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: Any printed circuit
boards within the data storage devices must be removed separately from the data storage
devices and shall be disposed or recovered in compliance with Directive 2008/98/EC.
Step 1 Step 2

below, the processor is located under the heat sink. The heatsink can look more like a fin type
thermal transfer device, or a rotating fan with a thermal transfer plate. There can be more than
one processor per motherboard, generally between 1- 4.
Type and number of fastenings: Four (4) T30 Torx screws.
Tools required: Screwdriver with T30 Torx bit.
Procedure: Remove the screws in the sequence of 4, then 3, then 2, then 1, as marked in the
illustration below. After removing the screws, lift the processor heatsink module off the
processor socket. Unsnap corners A and B, then C and D of the latch. Push the latch out from the
bottom.
Selective Treatment/Special Handling Per Annex VII, Directive 2012/19/EU: Any printed circuit
boards within the processor must be removed separately from the processor and shall be
disposed or recovered in compliance with Directive 2008/98/EC.

6. Expansion Card/Graphics Card
Location: Certain configurations of server may include a riser card bracket, this component
allows for utilization of the vertical space in a server, rather than only utilizing the horizontal
space. It is used for add-on types of components; it is attached directly to the motherboard. The
riser card would generally be populated, and the components integrated should be removed
prior to processing the riser card component.
Type and number of fastenings: Six (6) Phillips screws.
Tools required: Screwdriver with PH2 bit.
Procedure: Remove the Phillips screws. Open the rear window latch and carefully remove the
expansion card from the riser card slot, lifting it up and away from the system.
Selective Treatment/Special Handling Per Annex VII, Directive 2012/19/EU: Any printed circuit
boards within the expansion card/graphics card must be removed separately from the
expansion card/graphics card and shall be disposed or recovered in compliance with Directive
2008/98/EC.

ACE088 Page 14 of 21 Rev Date: 9.21.2021
7. Power Supply Module
Location: The power supply module is an interchangeable unit, and can be removed with ease
from the exterior, rear, portion of the server chassis. Many servers are equipped with redundant
power supplies (at least 2) in some instances there may be more than 2 power supplies
depending on the configuration.
Type and number of fastenings: One (1) latch per module.
Tools required: None.
Procedure: Unplug the power cord from the power supply. Push the release tab on the back of
the power supply module to the side and pull the module straight out.

resides on the motherboard. The battery must be removed from separately from the
motherboard and shall be disposed or recovered in compliance with Directive 2008/98/EC.
Removal instructions for the motherboard lithium battery are outlined below.
▪Handle used batteries carefully. Do not damage the battery in any way; a damaged battery may
release hazardous materials into the environment. Do not discard a used battery in the garbage
or a public landfill. Please comply with the regulations set up by your local hazardous waste
management agency to dispose of your used battery properly.

ACE088 Page 20 of 21 Rev Date: 9.21.2021
13. External Power Cable
Location: To power the server a power cable is required. The cable may be separate or attached
via a server rack mount power delivery system. The external power cable may be dual ended
with an outlet and inlet of the same plug configuration type or one end may be a plug type
connection. Configurations may vary. If the server is fully configured, the power supply cord
would be connected to the power supply outlet located on the rear of the server chassis. Note:
there are two power supplies per unit, so be aware for two power supply cords.
