The switch is a store-and-forward device that offers low latency for high-speed networking. 2. 1. 2 Rack-Mount Installation The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your switch on a standard EIA rack using the included rack-mounting kit. Align one bracket with the holes on one side of the switch and secure it with the bracket screws smaller than the rack-mounting screws. Similarly, attach the other brackets. Figure 2-2 Attaching Mounting Brackets and Screws Step 2. After attaching both mounting brackets, position the switch in the rack by lining up the holes in the brackets with the appropriate holes on the rack. Secure the switch to the rack with the rackmounting screws. 2-2 Hardware Description and Installation Dimension ES-108A/ES-1024A Ethernet Switch Figure 2-3 Mounting the ES to an EIA standard 19-inch rack 2. 2 Rear Panel The three-pronged power receptacle is located on the rear panel of the switch. Refer to the Product Specifications for power specification. Figure 2-4 Rear Panel 2. 2. 1 Rear Panel Power Connection Connect one end of the supplied power cord to the power receptacle on the back of the switch and the other end to the appropriate power source. Hardware Description and Installation 2-3 Dimension ES-108A/ES-1024A User's Guide 2. 3 Front Panel LED 16 RJ-45 Ports The front panel of the switch includes the auto-negotiating 10Base-T/100Base-TX RJ-45 ports and the LEDs. Figure 2-5 Front Panel: ES-108A LED 24 RJ-45 Ports Figure 2-6 Front Panel: ES-1024A 2. 3. 1 10Base-T/100Base-TX RJ-45 auto-negotiating ports Your switch comes with 16 or 24 10Base-T/100Base-TX 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 either 10 Mbps or 100 Mbps in either half- duplex or full-duplex mode depending on your Ethernet network. 2. 3. 2 Auto-crossover ports Each 10Base-T/100Base-TX RJ-45 MDI/MDIX port allows you to connect to a computer or to a hub using either a straight-through or a crossover Ethernet cable. 2. 3. 3 Front Panel Connections You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45 ports. The following table describes the types of network cable used for the different connection speeds. Make sure the cable length between connections does not exceed 100 meters (328 feet). 2-4 Hardware Description and Installation Dimension ES-108A/ES-1024A Ethernet Switch Table 2-1 Network Cable Types SPEED 10 Base-T 100 Base-TX NETWORK CABLE TYPE 100 2-pair UTP/STP Category 3, 4 or 5 100 2-pair UTP/STP Category 5 2. 3. 4 Front Panel LEDs The LED Indicators give real-time information about the status of the switch. The following table provides descriptions of the LEDs.

[. . . ] A data path loop forms when there is more than one path or route between two networked computers. This results in broadcast storms that will severely affect your network performance. Make sure there are no loops in your network topology.
