In interconnection networks, the ethernet switch or network switch is used to connect computers, printers and other network devices within an establishment. Its function is to control and enable network devices to communicate with each other efficiently. Network switches are mainly categorized as an unmanaged type or a managed type switch. Unmanaged type switches, are switches that do not need configuration for its installation, while managed type switches require configuration to be set up and be installed for its function. With this, the managed type switch offers greater flexibility and capacity than the unmanaged type switch. You can monitor and adjust a managed switch locally or remotely, which gives you greater network control.

The design is a 14-port gigabit managed ethernet switch with two Small Form-factor Pluggable (SFP) based from the Epsilon-12G2 module. The design offers twelve 10/100/1000 Mbps ethernet ports and two SFP sockets in a compact COM express form factor. The device has a built-in microcontroller and memory for configuration and management. The Flash memory holds dual application images along with the boot code. The SRAM is used for program execution and storing the MAC addresses while the EEPROM holds the configuration parameters. An RS-232 interface is provided to enable communication between the on-board management microcontroller and a host processor through a command-line interface. The microcontroller is also accessible through one of the Ethernet ports via a web management interface. The power is provided through the +5-40VDC wide-range DC power supply built into the board, enabling use with industrial power sources. In the design, a 2x1 stacked SFP connector is shown, in which a 2198318-6 zSFP+ connector from TE connectivity can be used. The connector features up to 10Gbps Ethernet and 16Gbps Fibre Channel. It has also backward compatibility with SFP+ connectors. The connector has a maximum rating of 120V AC for voltage and 0.5A for current.

This design is useful for data communication applications that improve the reliability. This can be found in ethernet switches, routers, firewalls and network interface cards. The storage interface cards, also called HBAs or fibre channel storage switches, make use of these modules, supporting different speeds such as 2 GB, 4 Gb, and 8 Gb. These connectors are also used in medical equipments and test equipments..
