2 Outline Structure of a Typical LAN Simplex vs. Duplex
Wiring and Making connectors Experiment Steps

3 Structure of a Typical LAN

4 Simplex vs. Duplex Baseband vs.Broadband
Duplex: 2 NICs using Twisted Pair Duplex: 2 NICs over one Hub

5 Connector and Wire Connector:RJ-45 Wiring:Category 5
NIC to Hub/Switch NIC to NIC Hub/Switch to Hub/Switch Before Making A Cable NIC Hub/Switch Wiring and Connectors

6 Connector : RJ-45 8P ? Colors vs. Twisted Pairs
W-O & O W-G & G W-BL & BL W-BR & BR 8 wires for 8 functions ? Nope !

7 Wiring : 5 Categories The 6th Category ?
Gears up for Gigabit Ethernet !!

8 3 Configurations NIC to Hub NIC to NIC Hub to Hub

9 Before Making A Cable NIC-driver configuration Hub/Switch Wiring
Caution Auto-Sense don’t always sense automatically

10 Experiment Steps (1/2) 製作五條網路線 RJ-45接頭安裝說明 使用剝線器撥掉外皮
<注意使用剝線器要小心不要剝到自己的手 > 將各絞線依序導入接頭中的小溝 放入壓線器8P的壓線孔中,接著用力夾緊,接頭即告完成

11 Experiment Steps (2/2) 測試線材與接頭 利用Hub(10/100Mbps)的燈號來測試每一條線是否正常
若網路線在測試步驟中都沒有使燈亮過,很有可能是您的製程有問題
