Air and Liquid Cooling Infrastructure Requirements
The PowerEdge XE9640 system has processors and GPUs and a few other minor components with direct liquid cooled 100%
of the time while other components like DDR5 DIMMs, PCIe cards, PSUs and storage are air cooled with a max inlet air
temperature of 35C.
Water inlet temperature requirement may vary based on several factors on a given deployment. Guidance is that we require 32C
primary water temperature but it may be possible to go higher under certain circumstances.
Liquid cooling components in a datacenter include facility water, cooling distribution units (CDU) and rack manifolds (looks like a
PDU but for water). The XE9640 has a higher flow-rate requirement. The rack manifold is not shared with the other platforms.
The rack manifold model numbers that are supported with the 42U XE9640 rack manifold and 48U XE9640 rack manifold. Each
can handle a full rack of each size.
The CDU's (Cooling distribution units) available that are supported with the XE9640 are the in-rack CHx80 and CHx200 models,
as well as the end-of-row CHx750 which is generally chosen for multi-rack liquid cooling XE9640 environments. Each model
number is indicative of the total number of kilowatts of cooling capacity, however there are many variables (T-case of CPUs in
your server configuration, flow rate of chilled facility water, temperature of water inlet from facility, etc).
Rack requirements will vary per customer depending on density, number of power supplies per server, PDU choices, and brand
preference - however the minimum supportable rack is 750mm wide by 1200mm deep. Standard 600m wide by 1070mm racks
are not supported.
Pictured below is a rack full of XE9640 demonstrating an in-rack CDU and the liquid manifold, which always goes on the right
side of the rack when facing from the back.
Figure 8. Direct Liquid Cooled Racks
Locating the Express Service Code and Service Tag
The unique Express Service Code and Service Tag is used to identify the system. The information tag is located on the front of
the system that includes system information such as Service Tag, Express Service Code, Manufacture date, NIC, MAC address,
QRL label, and so on. If you have opted for the secure default access to iDRAC, the Information tag also contains the iDRAC
secure default password. If you have opted for iDRAC Quick Sync 2, the Information tag also contains the OpenManage Mobile
(OMM) label, where administrators can configure, monitor, and troubleshoot the PowerEdge servers.

5. Service Tag, Express Service Code, QRL label
The Mini Enterprise Service Tag (MEST) label is located on the rear of the system that includes Service Tag (ST), Express
Service Code (Exp Svc Code), and Manufacture Date (Mfg. Date). The Exp Svc Code is used by Dell to route support calls to
the appropriate personnel.
Alternatively, the Service Tag information is located on a label on left wall of the chassis.
System information label
The system information label is located on the back side of the system cover.
