acquire a static electrical charge.
To protect your device, always:
•Touch the metal chassis of your computer to ground the static electrical charge before
you pick up the circuit device.
•Pick up the device by holding it on the left and right edges only.

1. Introduction
1-1. Overview of LGB1005A-R2
LGB1005A-R2, a 24-port Gigabit L2 Plus Managed Switch, is a standard switch
that meets all IEEE 802.3/u/x/z Gigabit, Fast Ethernet specifications. 16-Port 1000Mbps
SFP and 8-Port Combo Gigabit TP/SFP Fiber dual media management Ethernet switch.
The switch can be managed through RS-232 serial port via directly connection, or through
Ethernet port using CLI or Web-based management unit, associated with SNMP agent.
With the SNMP agent, the network administrator can logon the switch to monitor,
configure and control each port’s activity in a friendly way. The overall network
management is enhanced and the network efficiency is also improved to accommodate
high bandwidth applications. In addition, the switch features comprehensive and useful
functions such as QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking,
Bandwidth Control, Port Security, SNMP/RMON, IGMP Snooping capability via the
intelligent software. It is suitable for both metro-LAN and office applications.
In this switch, Port 1 and Port 8 include two types of media --- TP and SFP Fiber
(LC, BiDi LC…); this port supports 10/100/1000Mbps TP or 1000Mbps SFP Fiber with
auto-detected function. 1000Mbps SFP Fiber transceiver is used for high-speed
connection expansion.
⎯1000Mbps LC, Multi-Mode, SFP Fiber transceiver
⎯1000Mbps LC, 10km, SFP Fiber transceiver
⎯1000Mbps LC, 30km, SFP Fiber transceiver
⎯1000Mbps LC, 50km, SFP Fiber transceiver
⎯1000Mbps BiDi LC, 20km, 1550nm SFP Fiber WDM transceiver
⎯1000Mbps BiDi LC, 20km, 1310nm SFP Fiber WDM transceiver
10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE 802.3/u/x/z
Gigabit, Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver is a Gigabit
Ethernet port that fully complies with all IEEE 802.3z and 1000Base-SX/LX standards.
1000Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic
Wavelength Division Multiplexing (WDM) technology that transports bi-directional full
duplex signal over a single fiber simultaneously.
For upgrading firmware, please refer to the Section 3-21 or Section 4-2-2 for more
details. The switch will not stop operating while upgrading firmware and after that, the
configuration keeps unchanged.

• Key Features in the Device
QoS: Support Quality of Service by the IEEE 802.1P standard. There are two
priority queue and packet transmission schedule.
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol)
standards.
VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 256 active
VLANs and VLAN ID 1~4094.
Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Bandwidth Control:
Support ingress and egress per port bandwidth control.
Port Security:
Support allowed, denied forwarding and port security with MAC address.
SNMP/RMON:
SNMP agent and RMON MIB. In the device, SNMP agent is a client software
which is operating over SNMP protocol used to receive the command from SNMP
manager (server site) and echo the corresponded data, i.e. MIB object. Besides,
SNMP agent will actively issue TRAP information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of the
SNMP MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON MIB
(RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643), Ethernet MIB
(RFC 1643) and so on.
IGMP Snooping:
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used to
establish the multicast groups to forward the multicast packet to the member ports,
and, in nature, avoid wasting the bandwidth while IP multicast packets are
running over the network.
IGMP Proxy:
The implementation of IP multicast processing. The switch supports IGMP version
1 and IGMP version 2, efficient use of network bandwidth, and fast response time
for channel changing. IGMP version 1 (IGMPv1) is described in RFC1112 ,and
IGMP version 2 (IGMPv2) is described in RFC 2236. Hosts interact with the
system through the exchange of IGMP messages. Similarly, when you configure
IGMP proxy, the system interacts with the router on its upstream interface through
the exchange of IGMP messages. However, when acting as the proxy, the system
performs the host portion of the IGMP task on the upstream interface as follows:
•When queried, sends group membership reports to the group.
•When one of its hosts joins a multicast address group to which

11
none of its other hosts belong, sends unsolicited group
membership reports to that group.
•When the last of its hosts in a particular multicast group leaves
the group, sends an unsolicited leave group membership report
to the all-routers group (244.0.0.2).

2. Installation
2-1. Starting LGB1005A-R2 Up
This section will give users a quick start for:
- Hardware and Cable Installation
- Management Station Installation
- Software booting and configuration
2-1-1. Hardware and Cable Installation
At the beginning, please do first:
⇒Wear a grounding device to avoid the damage from electrostatic discharge
⇒Be sure that power switch is OFF before you insert the power cord to power source
• Installing Optional SFP Fiber Transceivers to the LGB1005A-R2
Note: If you have no modules, please skip this section.
•Connecting the SFP Module to the Chassis:
The optional SFP modules are hot swappable, so you can plug or unplug it
before or after powering on.
1. Verify that the SFP module is the right model and conforms to the chassis
2. Slide the module along the slot. Also be 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
slot(s)
5. Have the power ON after the above procedures are done

• TP Port and Cable Installation
⇒In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of cable,
straight-through and crossed-over can be used. It means you do not have to tell from
them, just plug it.
⇒Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the other
end is connected to a network-aware device such as a workstation or a server.
⇒Repeat the above steps, as needed, for each RJ-45 port to be connected to a Gigabit
10/100/1000 TP device.
Now, you can start having the switch in operation.
• Power On
The switch supports 100-240 VAC, 50-60 Hz power supply. The power supply will
automatically convert the local AC power source to DC power. It does not matter whether
any connection plugged into the switch or not when power on, even modules as well. After
the power is on, all LED indicators will light up immediately and then all off except the
power LED still keeps on. This represents a reset of the system.
• Firmware Loading
After resetting, the bootloader will load the firmware into the memory. It will take
about 30 seconds, after that, the switch will flash all the LED once and automatically
performs self-test and is in ready state.
