The motherboard provides CF, mSATA and SATA 3.0 storage connectivity. These three storage interfaces use a shared configuration and operate on a one-out-of-three basis.
- 1× CF card interface
- 1× mSATA interface
- 1× SATA 3.0 6Gbps interface
- CF / mSATA / SATA 3.0 — choose one
Available Memory & Storage Configurations
Select a barebone system or choose from the currently available RAM and storage combinations.
PCIe Expansion for More Network Interfaces
The physical PCIe x8 slot carries a PCIe 3.0 x4 signal and provides the expansion path used for the additional 2.5GbE or 10GbE network daughterboards.
- 1× physical PCIe x8 slot
- PCIe 3.0 x4 signal
- Optional 4× Intel i226-V 2.5GbE daughterboard
- Optional 2× Intel 82599ES 10GbE SFP+ daughterboard
19-Inch 1U Rackmount Chassis
440 × 320 × 45 mm
The standard CW-U2 sold online uses the compact 1U chassis, combining multiple network configurations with a rack-efficient form factor for firewall and network infrastructure deployments.
Power Supply Options by Network Configuration
The 4× 2.5GbE and 8× 2.5GbE versions each include one power supply as standard. The 4× 2.5GbE + 2× 10GbE SFP+ version includes two power supplies as standard; no additional power supply purchase is required for this version.
Want Dual Power Supplies for a 4-Port or 8-Port Version?
The 4× 2.5GbE and 8× 2.5GbE versions ship with a single power supply. To configure either of these versions with dual power supplies, purchase one additional compatible 1U power supply separately. The 4× 2.5GbE + 2× 10GbE SFP+ version already includes two power supplies.

N100, N150 and N200 are 4-core, 4-thread options focused on efficient network workloads. Core i3-N300 and Core i3-N305 provide 8 cores and 8 threads for workloads that require more processing headroom.
How many network ports can CW-U2 support?
The motherboard provides four native Intel i226-V 2.5GbE ports. Current configurations can expand this to eight 2.5GbE ports or combine the four native 2.5GbE ports with two 10GbE SFP+ ports.
What is the difference between the three network configurations?
The base version provides 4×2.5GbE. The second configuration adds another four Intel i226-V 2.5GbE ports. The third configuration adds two Intel 82599ES 10GbE SFP+ ports alongside the four onboard 2.5GbE interfaces.
Can CF, mSATA and SATA drives be used at the same time?
No. The CF card, mSATA and SATA 3.0 storage interfaces use a one-out-of-three configuration.
Does CW-U2 include dual power supplies?
It depends on the selected network configuration. The 4× 2.5GbE and 8× 2.5GbE versions include one power supply each. The 4× 2.5GbE + 2× 10GbE SFP+ version includes two power supplies. For dual power supplies on either of the first two versions, purchase one additional compatible 1U power supply .
Can CW-U2 be ordered as a 2U system?
Yes. The standard online product is 1U. The 2U chassis is available through pre-sales customization and bulk purchasing.
