Is this a managed switch or pass-through module?

It is an Ethernet Pass-Through Switch Module, not a managed switch. It delivers wire-speed 1Gb connectivity from 16 server ports directly to external uplinks, ideal for datacenters with existing infrastructure, minimizing latency and management overhead.

What Ethernet speed does it support?

All 16 ports operate at 1 Gigabit Ethernet speeds, supporting full-duplex 1000 Mbps transfers. This ensures non-blocking performance in blade server environments, compatible with IEEE 802.3ab for seamless integration into enterprise networks.

What form factor is required for installation?

It is a server module designed for HP c-Class BladeSystem enclosures. The compact form factor allows hot-plug installation in a single bay, providing high port density while maintaining efficient airflow and low power consumption.

What are the ideal applications for this module?

Best for datacenters needing direct 1GbE passthrough for blade servers, virtualization clusters, and HPC setups. With 16 ports, it connects multiple servers to upstream switches efficiently, reducing cabling and supporting existing 1Gb infrastructure.

Does it require additional power or cooling?

As a passive pass-through module, it draws minimal power from the enclosure and generates low heat. It integrates into standard HP BladeSystem power and cooling systems, with no extra requirements beyond the c-Class chassis compatibility.
