RJ-45 Auto-negotiating Ports
Your switch comes with 5 or 8 10/100/1000M RJ-45 ports depending on
the model of your switch. The auto-negotiation feature allows the switch
to detect the speed of incoming transmission and adjust appropriately
without manual intervention. It allows data transfers of 10 Mbps, 100
Mbps or 1000 Mbps in either half-duplex or full-duplex mode depending
on your Ethernet network.
Auto-sensing (MDI/MDIX) Ethernet Ports
Each Ethernet port allows you to connect to a computer or to a hub using
either a straight-through or a crossover Ethernet cable.
The following table describes the types of network cable used for the
different connection speeds.
Table 1 Ethernet Cable Type
SPEED NETWORK CABLE TYPE
10 Base-T 100 Ω 2-pair UTP/STP Category 3, 4 or 5
100 Base-TX 100 Ω 2-pair UTP/STP Category 5
1000 Base-T 100 Ω 4-pair UTP/STP Category 5
Cable length between connections must not
exceed 100 meters (328 feet).
Front Panel LEDs
The LEDs on the front panel indicate the real-time status of the switch.
