CHAPTER 2: Overview

2. Overview

2.1 Introduction

The Managed 24-Port 10/100/1000 Ethernet Switch with 2 SFP (Small Fiber Port) Dual Media meets all IEEE

802.3/802.3ab/802.3u/802.3x/802.1q Gigabit and Fast Ethernet specifications. It has 24 10/100/1000-Mbps twisted-pair ports and 2 Gigabit twisted-pair/SFP fiber slots for fiber modules. Connect 24 10/100/1000 twistedpair devices, 23 10/100/1000 twisted-pair and one fiber device, or 22 10/100/1000 twisted-pair and two fiber devices to the switch. Manage the switch through an Ethernet port using Web-based management. The network administrator can logon to the switch to monitor, configure, and control each port’s activity.

Ports 23 and 24 autodetect two media types: 10/100/1000-Mbps twisted pair and 1000-Mbps Small Fiber Port (SFP) fiber. An SFP fiber transceiver module is used for high-speed connection expansion. The 1000-Mbps SFP fiber transceivers are Gigabit Ethernet ports that fully comply with all IEEE 802.3z and 1000BASE-SX/LX standards. The switch is compatible with the following optional fiber modules.

• LC Multimode Fiber Module (LGB200C-MLC) works with 850-nm multimode fiberoptic cable that’s up to 960 feet (300 m) long

• LC Single-Mode Fiber Module (LGB200C-SLC10) works with 1310-nm single-mode fiberoptic cable that’s up to 6.3 miles (10 km) long

• LC Single-Mode Fiber Module (LGB200C-SLC30) works with 1550-nm single-mode fiberoptic cable that’s up to 18.9 miles (30 km) long

The switch features QoS (Quality of Service), VLAN, and trunking. QoS enables the switch to support the ToS field of an IP header (equal DSCP low 3 bits) on Layer 3 of network framework and six kinds of special network transmission events on Layer 4. With VLAN, the switch supports port-based VLAN and IEEE802.1Q Tag VLAN. It also supports 24 active VLANs and VLAN ID 1–4094. Port trunking allows one or more links to be aggregated together to form a Link Aggregation Group by the static setting.

2.2 Components

3. Installation

3.1 Hardware and Cable Installation

Before installing the switch, make sure you are wearing a grounding strap to avoid damage caused by electrostatic discharge. Also, confirm that the power switch is off before you insert the power cord into the power receptacle.

3.1.1 I

NSTALLING THE

OPTIONAL MODULES

NOTE

If you are not installing modules in Ports 23–24, skip this section.

1. Verify that the SFP module is the right model and conforms to the chassis.

2. Slide the module into the slot as shown in Figure 3-1. Make sure that the module is properly seated against the slot socket/connector.

Figure 3-1. Installing an optional SFP fiber transceiver in the switch.

3. Install the fiber optic cable (see Section 3.1.2) for network connection.

4. Repeat the above steps for the second module and slot, if needed.

5. Power on the switch.

CHAPTER 3: Installation

3.1.2 CONNECTING THE CABLE

The switch’s twisted-pair ports support MDI/MDI-X auto-crossover, so you can use either straight-through or cross-pinned UTP cable.

Use Category 5 or 5e grade RJ-45 twisted-pair cable to connect up to 24 network devices (such as workstations or servers) to the switch’s UTP ports.

Use 850-µm multimode, 1310-µm single-mode, or 1550-µm single-mode fiberoptic cable to connect the fiber module to the network.

3.1.3 P

OWERING ON THE

SWITCH

The switch supports a 100–240-VAC, 50–60-Hz power supply. The power supply will automatically convert the local AC power source to DC power. It doesn’t matter whether any devices are plugged into the switch or not when you power on the switch (including modules). Once the power is on, all LEDs (except for the Power LED) will light immediately and then turn off. The Power LED will remain on.

After resetting, the bootloader will load the firmware into memory. This takes approximately 30 seconds. After that, all LEDs will flash once and the switch will automatically run a self-test.

3.1.4 I

NSTALLING THE CHASSIS ON A DESKTOP

Attach the four included rubber feet to the switch’s bottom. Then place the switch on a desktop.

3.1.5 I

NSTALLING THE CHASSIS INTO A 19-INCH WIRING CLOSET RAIL

CAUTION

Allow extra space for proper air ventilation for the cooling fan on both sides of the chassis.

1. Wear a grounding strap to guard against electrostatic discharge.

2. Position the mounting brackets (included) on the switch’s front panel.

3. Attach four of the supplied mounting screws (two on the left, two on the right) to the switch’s sides to hold the bracket in place (see Figure 3-2).

MANAGED 24-PORT 10/100/1000 ETHERNET SWITCH WITH 2 SFP DUAL MEDIA

Figure 3-2. Chassis installation.

4. Position the chassis with mounting brackets attached in the 19-inch wiring closet rail.

5. Use the four remaining screws to connect the bracket-mounted chassis to the rail, then tighten the screws.

3.2 Cabling Requirements

3.2.1 TWISTED-PAIR PORTS

For either a Fast Ethernet or Gigabit Ethernet twisted-pair network connection, use Category 5 or 5e cable that’s 328 feet (100 m) long or shorter. We recommend Category 5e cable for Gigabit Ethernet networks.

3.2.2 F

IBER PORTS

Connect multimode fiber to the LGB200C-MLC module. Use single-mode fiber for the LGB200C-SLC10 or LGB200C-SLC30.

CHAPTER 3: Installation

3.2.3 VLAN EXAMPLES

If VLAN is enabled and configured, each network node that can communicate with each other directly is bound in the same VLAN area.

Example 1: Port-based VLAN

In Figure 3-3, VLAN is defined by what VLAN you are using. The switch supports both port-based VLAN and tag-based VLAN. They are different in practical use, especially in physical location.

Figure 3-3. Port-based VLAN.

In this example:

• The same VLAN members can’t be located on different switches.

• Every VLAN member can’t access all other VLAN members.

• The switch manager has to assign different names for each VLAN group at one switch.

3.3 Management

Configure and monitor the switch in two ways: via the switch’s SNMP management port or via a Web browser. Chapter 4 explains how to access and use the Web-based management interface. SNMP management is not described in this manual since it depends on your network management system.

3.4 Assigning an IP Address

For IP address configuration, you need to type in three parameters: IP address, subnet mask, and default gateway. Your system administrator can tell you what these values are for your network. See Figure 4-2 in Chapter 4.

VLAN Mode (continued) Tag-based VLANs identify their members by VID. This option considers

any Ingress or Egress list filtering rules required for the switch before forwarding a packet.

Each tag-based VLAN must be assigned a VLAN name and VLAN ID. Valid VLAN IDs are from 1 to 4094. You can create up to 24 tag-based VLANs.

Metro mode is a quick configuration VLAN environment method used for port-based VLANs. It will create 22 or 23 port-based VLAN groups.

Uplink Port This option is only enabled when you select Metro mode from the drop-

down menu in Figure 4-5.

When you select 23 from the drop-down menu: Except for port 23, each switch port can’t transmit packets to each other. Each port groups a VLAN with Port 23, so a total of 23 groups consisting of two members are formed.

When you select 23 and 24 from the drop-down menu: Except for ports 23 and 24, each switch port can’t transmit packets to each other. Each port groups a VLAN with port 23 and port 24. A total of 22 groups consisting of three members are formed.

State Available only if you choose Tag-based VLAN from the drop-down menu

in Figure 4-5. When you select Enable from the drop-down State menu, only tagged packets with this VID can manage the switch.

VID Type in a value between 1 and 4094.
