SW4 and SW5 - Port 2 Pause Advertisement “OFF PAUSE” “OFF ASYM”

These DIP-switches are only valid when Port 1 is set to “MAN”. The PAUSE modes will be based on the configuration of DIP-switches SW4 and SW5.

SW4	SW5	Port 2 (UTP) PAUSE Modes
OFF	OFF	No Pause advertised
OFF	ASYM	Asymmetric PAUSE towards link partner
PAUSE	OFF	Symmetric PAUSE
PAUSE	ASYM	Both Symmetric PAUSE and Asymmetric PAUSE
		toward local device

SW6, SW7, SW8 - Link Modes

These three DIP-switches configure the link mode settings. DIP-switch SW6 is valid when Port 1 is set to “AN” or “MAN”. DIP-switches SW7 and SW8 are ignored when Port 1 is set to “AN”. The following table details possible Link Mode DIP-switch configurations.

NOTE: Connecting two converters set to any of the RFD modes is illegal and will cause a “deadly embrace” lockup.

NOTE: It is recommended to keep the LS setting (default) until initial configuration is complete.

2) SET-UP MODULE AND CONNECT CABLES

a.The Gx AN is available in tabletop and wall-mounting models. For wall-mounting, attach the unit to a wall, backboard or other flat surfaces. For tabletop installations, place the unit on a flat level surface. Attach the rubber feet to the bottom of the unit to prevent the unit from sliding. Make sure the unit is placed in a safe, dry and secure location.

To power the unit using the AC/DC adapter, connect the AC/DC adapter to the AC outlet. Then connect the barrel plug at the end of the wire on the AC/DC adapter to the 2.5mm DC barrel connector (center-positive) on the chassis. Confirm that the unit has powered up properly by checking the power status LED located on the front of the unit.

To power the unit using a DC power source, prepare a power cable using a two- conductor insulated wire (not supplied) with a 14 AWG gauge minimum. Cut the power cable to the length required. Strip approximately 3/8 of an inch of insulation
