One Core Activation Key (for Embedded)
Need to order at the same time of the server. As many CPU cores as the ordered
number of the One Core Activation Key (for Embedded) are to be enabled when
the ordered server is shipped.
Up to the ordered number of the One Core Activation Key (for Embedded), CPU
cores are available for use.
NE3401-H010F
One Core Activation Key (for Add-on)
The enabled CPU core can be added on-site.
As many Code Words as the ordered number of the One Core Activation Key (for
Add-on) are shipped, and additional CPU core can be enabled by applying the
Code Word to the server.

1.5 COPT
Capacity Optimization (COPT) is a function to optimize computing resources by enabling CPU cores as many
required per workload without any impact to the number of DIMM and PCI slots which depends on CPU
configuration.
When necessary, CPU core can be enabled additionally on-site.
COPT is available only with A2040b COPT supported model (NEC Express5800/A2040b (COPT)).
In order to enable CPU core, Core Activation Key should be ordered for the required number of cores.
NOTE:
Contact to our sales representative for software supporting COPT function.
When enabling CPU core (or socket) by Core Activation Key, please purchase required software license
as appropriate
In case of using socket license based software, please enable CPU core at the CPU socket on which the
software is operating. Software license is required for the socket with at least one enabled CPU core.
Depending on the OS, the server may need to be rebooted to enable CPU cores
Remarks to use COPT under VMware environment:
- Need to purchase the same number of One Core Activation Key as the number of CPU socket.
- Need to enable the same count of CPU cores among all CPUs (excluding CPUs with all cores
disabled)
<Examples of OK or NG configuration in case of 4CPU configuration>
For the details, please refer to the latest version of “Express5800/A2040b Capacity Optimization (COPT)
User's Guide”
Default setting of Core Optimization Mode is “Decentralize”, where the enabled CPU cores are
distributed to each socket equally.

CONFIGURATION GUIDE – NEC Express5800/A2040b, A2020b, A2010b, A1040b
Memory Riser Card (“MR”) is a module for installing up to 8 DIMM
Please refer to “Memory” of “Reference” section for Memory Riser Card installation priority/order.
For A2040b (including COPT model), A2020b,A2010b
NOTE:
A2040b: 1 to 2 MRs can be installed per CPU, thus up to 8 MRs can be installed with 4CPU configuration
A2020b: Up to 8 MRs can be installed
A2010b: Up to 4 MRs can be installed
Not pre-installed in Base Model. At least one MR needs to be ordered.
Cover for Hot-plug is attached
NE3402-H001 and NE3402-H002 can be mixed in one server.
For A1040b
NOTE:
1 to 2 MRs can be installed per CPU, thus up to 8 MRs can be installed with 4CPU configuration
Not pre-installed in Base Model. At least one MR needs to be ordered.
NE3302-H001 and NE3302-H002 can be mixed in one server.
Customized Configuration Service (at the Server Delivery)
NOTE:
This service can be ordered only for A2040b COPT Model and up to one item (service) can be ordered
per one server.
With this service, the location of MR can be changed from the standard BTO Configuration.
When allocating enabled CPU cores to all CPU (distributed), this service is recommended to use so that
MR and Memory can be distributed, too. Please refer to “Memory” of “Reference” section for Memory
Riser Card installation priority/order.
