A BOUT T HIS G UIDE Congratulations on your purchase of the 24-Port 10/100Mbps Ethernet Switch with 2 × 1000BASE-T Gigabit ports. This device integrates Gigabit, 100Mbps Fast Ethernet, and 10Mbps Ethernet network capabilities in a highly flexible package. Purpose This guide discusses how to install your 24-Port 10/100Mbps with 2× 1000BASE-T ports Switch.
I NTRODUCTION This chapter describes the features of the Switch and some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of highspeed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times.
Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time. The phenomenal bandwidth delivered by Gigabit Ethernet was the most cost-effective method to take advantage of today’s rapidly improving switching and routing internetworking technologies.
. Wire speed reception and transmission . Store-and-Forward switching method . Integrated address Look-Up Engine, supports 8K MAC addresses . Supports 512K bytes RAM for data buffering . Extensive front-panel diagnostic LEDs . IEEE 802.3x flow control for full-duplex . Back pressure flow control for half-duplex .
U NPACKING AND I NSTALLATION This chapter provides unpacking and installation information for the Switch. To avoid causing any damage to the Switch, we recommend that you read this chapter carefully before starting installation. Unpacking Open the shipping carton of the Switch and carefully unpack the items inside.
Figure 1. Attach the adhesive rubber pads to the bottom Rack Mounting The Switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipments. Attach the mounting brackets to both sides of the Switch (one at each side), and secure them with the provided screws. Figure 2. Combine the Switch with the provided screws Then, use screws provided with the equipment rack to mount the Switch in the rack.
Figure 3. Mount the Switch in the rack Connecting Network Cable The Switch supports 10/100/1000Mbps Gigabit Ethernet. It runs full/half duplex transfer mode for 10/100Mbps and full duplex transfer mode for 1000Mbps. These ports are Auto-MDI type. The Switch can auto configure to MDI-II or MDI-X type, so you can make a connection without worrying if you are using a standard or crossover cable. AC Power The Switch can be used with AC power supply 100~240V AC, 50~60 Hz.
I DENTIFYING E XTERNAL C OMPONENTS This chapter identifies all the major external components of the Switch. Both the front and rear panels are shown below, with a description of each panel feature. Front Panel 10/100 BASE-T X Twisted-Pair Ports LED Indicators 1000 BASE-T Twisted-Pair Ports Figure 4. The front panel of the Switch LED Indicators Refer to the next chapter Understanding LED Indicators for detailed information on the meaning of each LED indicator.
Rear Panel Power Switch Power Connector Figure 5. The rear panel of the Switch AC Power Connector This is a three-pronged connector that supports the power cord. Plug in the female connector of the provided power cord into this connector, and the male into a power outlet. Supported input voltages range from 100~240V AC at 50~60Hz. Power Switch Use the power switch beside this power connector to turn on or turn off the power of the Switch.
U NDERSTANDING LED I NDICATORS The front panel LEDs provide instant status feedback, and, helps monitor and troubleshoot when needed. Figure 6. LED indicators of the Switch Power LED POWER On : When the Power LED lights on, the Switch is receiving power. Off : When the Power LED turns off or the power cord has improper connection. Ports 1~24 Status LEDs LINK/ACT On : When the LED lights on, the respective port is connected to the 10/100Mbps Ethernet network.
Port 25 & Port 26 Status LEDs LINK/ACT On : When the LED lights on, the respective port is connected to a 10/100/1000Mbps Ethernet network. Blinking : When the LED is blinking, the respective port is transferring or receiving data on a 10/100/1000Mbps Ethernet network. Off : No link. 1000Mbps On : When the LED lights on, the respective port is connected to a Gigabit Ethernet network. Off : The respective port is connected to a 10/100Mbps Ethernet network, or no link.
