Two DIP Switch Layouts
This layout has one six-position DIP Switch and one four-position DIP Switch. The DIP switches are
located on the right side of the SGFEB (SGFEB1040-230 or SGFEB1040-330).Use a small, flat-blade
screwdriver (or a similar device) to set the DIP switches according to your site requirements.
The SGFEB version with two SFP ports supports two modes, controlled via DIP switches (Multi-port
switch mode and Redundant fiber path mode).
A. 6-Position DIP switch:
1 - Twisted Pair Port 2 Autonegotiation: Up = Enabled, Down = Disabled.
2 - Twisted Pair Port 2 Speed: Up = 100Mbps, Down = 10Mbps (only for Autoneg disabled).
3 - Twisted Pair Port 2 Duplex: Up = Full, Down = Half (only for Autoneg disabled).
4 - No affect; Link Pass Through does not apply to 3-port and 4-port models.
5, 6 (Port control): Port 1 (SFP)
