This chapter describes how to connect the TEG-S40SX to your 

Gigabit Ethernet network. 

PC to Switch 

A PC can be connected to the Switch via a fiber optic cable. The PC 

should be connected to any of the four ports  (1x - 4x) of the TEG-

S40SX.   

Figure 4-1.  TEG-S40SX Switch connected to a PC or 

Workstation (full-duplex mode is required) 

The LED indicators for PC connection are dependent on the LAN 

card capabilities. If LED indicators are not illuminated after
