24-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet

Chapter 1

Introduction

Chapter 1:

Introduction

Thank you for choosing the 24-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet.. This Switch will allow you to network better than ever.. The 24-Port 10/100 + 4-Port Gigabit Switch with WebView delivers non-blocking, wire speed switching for your 10 and 100 megabit network clients, plus multiple options for connecting to your network backbone.. Twenty Four 10/100 ports wire up your workstations, while the four integrated 10/100/1000 ports connect to other switches and the backbone at Gigabit speeds.. The miniGBIC ports allow future expansion through alternate transmission media like optical fiber..

All of the 10/100 ports on the Switch support pre standard and IEEE 802..3af standard (802..3af) Power over Ethernet (PoE) capabilities.. Each port can detect connected pre standardand802..3af-compliantnetworkdevices,such as IP phones or wireless access points, and automatically supply the required DC power..

The Switch can provide DC power to a wide range of connected devices, eliminating the need for an additional power source and cutting down on the amount of cables attached to each device.. Once configured to supply power, an automatic detection process is initialized by the Switch that is authenticated by a PoE signature from the connected device.. Detection and authentication prevent damage to non-PoE devices..

TheSwitchfeaturesWebViewmonitoringandconfiguration via your web browser, making it easy to manage the 256 VLANs and up to 8 trunking groups.. Or if you prefer, you can use the integrated console port to configure the Switch.. The non-blocking, wire-speed switching forwards packets as fast as your network can deliver them..

All ports have automatic MDI/MDI-X crossover detection.. Each port independently and automatically negotiates the best speed and whether to run in halfor full-duplex mode.. Head-of-line blocking prevention keeps your high speed clients from bogging down in lower-speed traffic and fast store-and-forward switching prevents damaged packets from being passed on into the network..

Use the instructions in this User Guide to help you connect the Switch, set it up, and configure it to bridge your different networks.. These instructions should be all you need to get the most out of the 24-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet..

Product Overview

ETHERNET 1-24  These RJ-45 ports support network speeds of either 10Mbps or 100Mbps, and can operate in half and full-duplex modes.. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it (10Mbps or 100Mbps), and adjust its speed and duplex accordingly..

The Switch’s 10/100 RJ-45 ports also support the IEEE 802..3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devicesusingwiresintheconnectingtwisted-pair cable.. Any 802..3af-compliant device attached to a port can directly draw power from the Switch over the twisted-pair cable without requiring its own separate power source.. This capability gives networkadministratorscentralizedpowercontrol for devices such as IP phones and wireless access points, which translates into greater network availability..

For each attached 802..3af-compliant device, the Switch automatically senses the load and dynamically supplies the required power.. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable.. Each port can provide up to 15..4W of power at the standard -48 VDC voltage..

To connect a device to a port, you will need to use Category 5 (or better) network cable..

ETHERNET G1-G4  The Switch is equipped with four Gigabit RJ-45 ports, two that are shared with two miniGBIC ports.. If a Gigabit miniGBIC port is being used, the associated RJ-45 port (G3 and/or G4) cannot be used..

All four ports support auto negotiation, so the optimum transmission mode (half or full duplex) and data rate (10, 100, or 1000 Mbps) can be selected automatically, if this feature is also supported by the attached device.. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually..

Each port also supports IEEE 802..3-2002 auto negotiation of flow control, so the Switch can automatically prevent port buffers from becoming saturated..

These ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs, servers, or additional switches..

Chapter 2

MiniGBIC (1-2)  The Switch is equipped with two miniGBIC ports that have shared Gigabit Ethernet ports (G3 and G4) which provide for the installation of one expansion module.. These ports provide links to high-speed network segments or individual workstations at speeds of up to 1000Mbps (Gigabit Ethernet)..

To establish a Gigabit Ethernet connection using a miniGBIC port, you will need to install a MGBT1, MGBSX2, or MGBLH1 Gigabit expansion module and use Category 5e cabling or fiber optic cabling..

To establish a Fast Ethernet connection using a miniGBIC port, you will need to install a MFEFX1 (100BASE-FX) or MFELX1 (100BASE-LX) 100SFP Transceiver and use fiber optic cabling..

Fast Ethernet Considerations

If you are using the Switch for Fast Ethernet (100Mbps) applications, you must observe the following guidelines:

Connecting the Switch

Full-Duplex Considerations

The Switch provides full-duplex support for its RJ-45 ports.. Full-duplex operation allows data to be sent and received simultaneously, doubling a port’s potential data throughput.. If you will be using the Switch in full-duplex mode, the maximum cable length using Category 5 cable is 328 feet (100 meters)..

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100Base-TX connections should also work for 1000Base-T, providing that all four wire pairs are connected.. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or Category 6 cable should be used.. The Category 5e specification includes test parameters that are only recommendations for Category 5.. Therefore, the first step in preparing existing Category 5 cabling for running 1000Base-T is a simple test of the cable installation to be sure that it complies with the IEEE 802..3ab standards..

Positioning the Switch

Before you choose a location for the Switch, observe the following guidelines:

•Make sure that the Switch is accessible and that the cables can be connected easily..

•Keep cabling away from sources of electrical noise, power lines, and fluorescent lighting fixtures..

•Position the Switch away from water and moisture sources..

•To ensure adequate air flow around the Switch, be sure to provide a minimum clearance of two inches (50mm)..

•Do not stack free-standing Switches more than four units high..

Placement Options

There are two ways to physically install the Switch, either set the Switch on its four rubber feet for desktop placement or mount the switch in a standard-sized, 19-inch high rack for rack-mount placement..

Chapter 3

Connecting the Switch

Desktop Placement

•Attach the rubber feet to the recessed areas on the bottom of the Switch..

•Place the Switch on a desktop near an AC power source..

•Keep enough ventilation space for the switch and check the environmental restrictions mentioned in “Appendix C: Specifications” as you are placing the Switch..

•Connect the Switch to network devices according to the Hardware Installation instructions below..

Attaching the Switch’s Rubber Feet

Rack-Mount Placement

To rack-mount the Switch in any standard 19-inch rack, follow the instructions described below..

1. Place the Switch on a hard flat surface with the front panel faced towards your front side..

2. Attach a rack–mount bracket to one side of the Switch with the supplied screws and secure the bracket tightly..

Attaching the Brackets

3. Follow the same steps to attach the other bracket to the opposite side..

4. After the brackets are attached to the Switch, use suitable screws to securely attach the brackets to any standard 19-inch rack..

Mounting in Rack

5. Connect the Switch to network devices according to the Hardware Installation instructions below..

Hardware Installation

To connect network devices to the Switch, follow these instructions:

1. Make sure all the devices you will connect to the Switch are powered off..

2. Connect a Category 5 Ethernet network cable to one of the numbered ports on the Switch..

3. Connect the other end to a PC or other network device..

4. Repeat steps 2 and 3 to connect additional devices.. If pre-standard or 802..3af-compliant PoE devices are connected to the Switch’s 10/100 ports, the Switch automatically supplies the required power..

5. If you are using a miniGBIC port, then connect a miniGBIC module to the miniGBIC port.. For detailed instructions, refer to the module’s documentation..

6. Connect the supplied power cord to the Switch’s power port, and plug the other end into an electrical outlet.. When connecting power, always use a surge protector..

7. Power on the devices connected to the Switch.. Each active port’s corresponding LED will light up on the Switch..

Uplinking the Switch

To uplink the Switch, connect one end of a Cat 5 (or better) Ethernet network cable into one of the 4 gigabit ports, and then connect the other end of the cable into the peripheral device’s uplink port.. MDI/MDIX will automatically detect the speed and cable type..

System PoE Configuration

The Power Configuration screen allows you to set the PoE power allocation from the Switch to connected devices..

System PoE Configuration

The Switch’s power management enables total Switch power and individual port power to be controlled within a configuredpowerbudget..Portpowercanbeautomatically turned on and off for connected devices, and a per-port power priority can be set so that the Switch never exceeds its allocated power budget.. When a device is connected to a port, its power requirements are detected by the Switch before power is supplied.. If the power required by a device exceeds the power budget of the port or the whole Switch, power is not supplied..

Port PoE Status

The Power Port Status screen allows you to view the current PoE settings for each port on the Switch..

Power Port Status

Ports can be set to one of three power priority levels: critical, high, or low.. To control the power supply within the Switch’s budget, ports set at critical or high priority have power enabled in preference to those ports set at low priority.. For example, when a device is connected to a port set to critical priority, the Switch supplies the required power, if necessary by dropping power to ports set for a lower priority.. If power is dropped to some low-priority ports and later the power demands on the Switch fall back within its budget, the dropped power is automatically restored..

Port PoE Configuration

The Power Port Configuration screen allows you to set the PoE settings for each port.. Select the Edit action and use the left-right and up-down arrows to select the attribute you would like to set..
