Gigabit Smart Switch Eco Fanless Quick Start Guide
1. Overview
The Gigabit Smart Switch Eco Fanless is a standard switch that meets all IEEE 802.3/u/x/z Gigabit and Fast Ethernet specifications.
The LGB2118A switch has (16) 10-/100-/1000-Mbps TP ports and (2) Gigabit SFP fiber transceiver slots. The LGB2124A switch has
(20) 10/100/1000Mbps TP ports and (4) Gigabit dual media TP/SFP transceiver slots. Both switches support http and SNMP
interfaces for switch management. The network administrator can logon to the switch to monitor, configure, and control each
port’s activity. In addition, the switch implements Quality of Service (QoS), VLAN, and Trunking.
The LGB2118A switch’s Ports 17 and 18 support SFP fiber modules (with LC connectors). The LGB2124A switch’s Ports 21, 22, 23,
and 24 include two types of media—TP and SFP Fiber (with LC connectors). The four combo ports on the LGB2124A support
10-/100-/1000-Mbps TP or 1000-Mbps SFP Fiber with auto-detection. A 1000-Mbps SFP Fiber transceiver is used for high-speed
connection expansion.
Table 1-1. 1000-Mbps SFP fiber transceivers.

3. Starting Up the Switch
This section will give users a quick start for:
• Hardware and cable installation.
• Management station installation.
• Software booting and configuration.
3.1 Hardware and Cable Installation
CAUTION:
Wear a grounding device to avoid damage from electrostatic discharge.
Make sure that the power switch is OFF before you insert the power cord into the power source.
Installing Optional SFP Fiber Transceivers to the Gigabit Smart Switch Eco Fanless
NOTE: If you have no modules, please skip this section.
Figure 3-1. Installing an optional SFP fiber transceiver.
Connecting the SFP module to the chassis:
The optional SFP modules are hot swappable, so you can plug or unplug them before or after powering on.
1. Verify that the SFP module is the right model and conforms to the chassis.
2. Slide the module into the slot. Make sure that the module is properly seated against the slot socket/connector.
3. Install the media cable for network connection.
4. Repeat the above steps, as needed, for each module to be installed into the slot(s).
5. Power ON the switch after the above procedures are done.
TP Port and Cable Installation
The switch’s TP ports support MDI/MDI-X auto-crossover, so you can use straight-through or crossover cable.
Connect CAT5 grade RJ-45 TP cable to a TP port of the switch and connect the other end to a network-aware device such as a
workstation or a server.

Gigabit Smart Switch Eco Fanless Quick Start Guide
Repeat the above steps, as needed, to connect each RJ-45 port to a Gigabit 10/100/1000 TP device.
The switch is ready to operate.
Power On
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. The switch‘s ports are hot-swappable, so you can plug in devices or SFPs while the switch is powered on.
After the power is on, all LED indicators will light on and then all will go off except for the power LED, which remains on. This
resets the system.
Firmware Loading
After resetting, the bootloader will load the firmware into the memory. It will take about 30 seconds; after that, all the LEDs on
the switch will flash once while the switch performs a self-test and is ready to use.
3.2 Cabling Requirements
For successful installation and good network performance, follow these cabling requirements. Low-quality cables can cause the
switch to malfunction.
Cabling Requirements for TP Ports
For Fast Ethernet TP network connections, use CAT5 or CAT5e cable that’s up to 328 feet (100 m) long. For Gigabit Ethernet TP
network connections, use CAT5 or CAT5e cable that’s up to 328 feet (100 m) long. We recommend using CAT5e cable.
Cabling Requirements for 1000SX/LX SFP Modules
There are two categories of fiber: multimode (MM) and single-mode (SM). Single-mode cable is categorized into several classes
by the distance it supports. They are SX, LX, LHX, XD, and ZX.
The following table lists the types of fiber that the switch supports. If you don’t see the cable type you need, contact Black Box
Technical Support at 724-746-5500 or [e-mail].

4. Configuring the Management Agent of the Gigabit Smart Switch Eco Fanless
Via the Web, the switch can set up the management function. Use any one of them to monitor and configure the switch.
Configuring the Management Agent of the Gigabit Smart Switch Eco Fanless through the Ethernet Port
There are two ways to configure and monitor the switch through the switch’s Ethernet port. They are Web browser and SNMP
manager. The user interface for the SNMP manager is management software-dependent and is not described in this manual.
Using the Web-based UI for the switch is described here.
24-Port Gigabit Smart Switch Eco Fanless
Default IP setting:
IP = 192.168.1.1
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254
Ethernet LAN
Assign a reasonable IP address, for
example:
IP = 192.168.1.100
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254
Figure 4-1. Gigabit Smart Switch Eco Fanless.
Managing the Gigabit Smart Switch Eco Fanless through the Ethernet Port
Before you communicate with the switch, you must first configure its IP address or know the IP address of the switch. Then,
follow the procedures described next.
1. Set up a physical path between the configured switch and a PC, using a qualified UTP CAT5 cable with an RJ-45
connector.
NOTE: If a PC directly connects to the switch, you have to set up the same subnet mask between them. However, the subnet
mask may be different for the PC in the remote site. See Figure 4-1 for default IP address information of the 24-Port
Gigabit Smart Switch Eco Fanless.
2. Run a Web browser and follow the menu. Please refer to Chapter 5 in the user manual for more information.
