EM316-2SFP User Guide 2 Product Overview The EM316-2SFP transparent converter contains two MSA compliant SFP sockets connected back- to-back. No components on the EM316-2SFP board are connected to the data path, so the module is considered transparent. Supported speed ratings range from 100 Mbps up to 2.7 Gbps where speed- matching or multi-rate SFPs are required in both ports. This EM316-2SFP converter is hot-pluggable, and it is managed through the Fiber Driver management bus fro

EM316-2SFP User Guide 2.1.2 Loopback The EM316-2SFP module supports loopback either by DIP switch setting or controlled through the CLI or SNMP software settings. For software control the Loopback DIP switch must be set to OFF. It the Loopback switch is ON, it cannot be over-ridden by software. Loopback is one way to assure that the fiber optical communication path is valid and error free. Packets sent over a short-circuit link should be received by the sender without any

EM316-2SFP User Guide 3.3 DIP Switch Configuration The EM316-2SFP factory default configuration is designed to operate in the most common applications. Network Management = Enabled LIN = Disabled Loopback = Disabled The default configuration optimizes the EM316-2SFP module in most applications. Network management configuration does not override hardware DIP switch settings. These settings can only be changed using the DIP switches (SW1) on the EM316-2SFP module, regardless
