Connecting Devices
RJ-45 Switch Ports
RJ-45 connectors are located on the front panel of the switch.
NOTE:
Ensure that Category 5E (CAT 5E) cabling is used for connecting devices at 1000-Mbps Gigabit Ethernet speed.
All ports can negotiate full- and half-duplex modes automatically. These switching ports allow users to connect the switches to 10Base-T, 100Base-TX and
1000Base-T devices.
SFP Port
On the 24-port switch, you can use the SFP port to connect to a device that is more than 100 meters away. However, using the SFP port disables the RJ-45
connector of port 24 on the switch.
Connecting Switches to Each Other
Each port supports Auto MDI and MDIX functionality. When cascading with other switches or hubs, each port can connect directly to a switch or hub with
straight-through twisted-pair cable (see Figure 1-4).
NOTE:
Do not connect two switches together with more than one cable. Using multiple cables to connect switches can create a loop and cause
collisions.
