Shared Motherboard Platform Across S1, S2, S6 and S8

CW-S1, CW-S2, CW-S6 and CW-S8 use the same core motherboard platform. Their primary differences come from the enclosure, physical dimensions and cooling design rather than the underlying network and expansion architecture.

One Shared Motherboard The four models share the same dual 10GbE SFP+, dual 2.5GbE, DDR5, NVMe and SATA architecture.

Four Chassis Designs S1, S2, S6 and S8 use different enclosure designs and thermal structures around the same core motherboard platform.

Dual-Fan Active Cooling for Sustained Network Workloads

CW-S1 uses an active cooling structure with two CPU cooling fans together with the aluminum chassis to manage system heat during sustained firewall, routing and high-speed networking workloads.

CPU Fan 1 Provides active airflow for the internal processor and thermal structure.

CPU Fan 2 Works alongside the primary fan to improve internal airflow and heat removal.

Aluminum Chassis The enclosure provides additional external surface area for overall thermal dissipation.
