Ethernet Cables
The ESW-5242GP / ESW-5162GP switches have standard Ethernet ports. According to the link type, the switches use CAT
3, 4, 5,5e UTP cables to connect to any other network device (PCs, servers, switches, routers, or hubs). Please refer to
the following table for cable specifications.

The ESW-5242GP / ESW-5162GP switches support auto MDI/MDI-X operation. You can use a straight-through cable to
make a connection between PC and switch. The following table below shows the 10BASE-T/ 100BASE-TX MDI and MDI-X
port pin outs.

Fibers
The ESW-5242GP / ESW-5162GP switches have fiber optical ports with SFP connectors. The fiber optical ports are in
multi-mode (0 to 550M, 850 nm with 50/125
μ
m, 62.5/125
μ
m fiber) and single-mode with LC connector. Please
remember that the TX port of Switch A should be connected to the RX port of Switch B.
