Fiber Driver ® EM316SW-XY PN 1288003-001, Rev D2 1 2 Module Introduction The Fiber Driver EM316SW-XY is a highly configurabl e multi-function module that can perform the functions of hundreds of less sophisticated devices. The S W-XY can operate in four modes.
Fiber Driver ® EM316SW-XY PN 1288003-001, Rev D2 2 2.1.1 Loopback Loopback tests and verifies the link integrity. It is available o n the fiber optic ports (P2 and P3 ) only, and it operates in all four operational modes. Loopback directs received data on a port to the transmitter to test the fiber optic lin k end-to-end from the remote converter.
Fiber Driver ® EM316SW-XY PN 1288003-001, Rev D2 3 2.1.2 Link Integrity Notifica tion (LIN) LIN is not available in switch mode. A single DIP switch (LIN EN) activates LIN for t he entire module except in switch mode. If this switch is OFF, then LIN cannot be activated even through software management.
Fiber Driver ® EM316SW-XY PN 1288003-001, Rev D2 4 2.2 Modes of Operation The EM316SW-XY supports four different operational modes. 1. Dual Repeater (Fiber and Copper) 2. Dual Converter 3. Redundant Link 4. Switch (4-Port, mixed-media) This section describes these modes and required DIP switch settings.

Fiber Driver ® EM316SW-XY PN 1288003-001, Rev D2 7 2.2.3 Redundant Link MODE1 OFF MODE0 ON Figure 4 -- Redundant Link Mode In Redundant Link mode, the module acts as a copper to redundant fiber (100Base-FX) converter. This configuration requires optical SFPs installed in ports P2 and P3 to support a pair of redundant fiber optic paths.
Fiber Driver ® EM316SW-XY PN 1288003-001, Rev D2 8 2.2.4 Mixed-Media Switch (4-Port) MODE1 OFF MODE0 OFF Figure 5 -- Switching Mode In Switch mode, the module acts a mixed-m edia Ethernet Switch with two 10/100Base-TX copper interfaces and two fiber-optic SFP-based 100 Base-FX interfaces.
