1. Introduction
1-1. Overview of 3-Slot 24 Fast Ethernet + 2 Gigabit L2 Managed
Switch with Redundant Power
3-Slot 24 Fast Ethernet + 2 Gigabit L2 Managed Switch with redundant
power, implemented 24 10/100Mbps TP or 100Mbps fiber + 2 Gigabit dual media
ports with TP/SFP, is a standard switch that meets all IEEE 802.3/u/x/z Gigabit, Fast
Ethernet and Ethernet specifications. The switch can be managed through RS-232
serial port via directly connection, or through Ethernet port using Telnet 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 function
such as QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking, Bandwidth
Control, Port Security, SNMP/RMON and IGMP Snooping capability via the
intelligent software. It is suitable for both metro-LAN and office application.
• Model Description
The switch not only supports 3 slots for removable and hot swappable 8-port
10/100M TP or 100M fiber module respectively but also 2 Gigabit dual media
ports(TP/SFP), in which 2 slots for removable SFP module supporting 1000M SFP
fiber module only.

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 3-20 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 using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on either VLAN tag on packets or user-defined port priority.
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree
Protocol) and IEEE 802.1s (MSTP: Multiple 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, VLAN MIB (802.1Q, RFC2674),
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.

2. Installation
2-1. Starting 3-Slot 24 Fast Ethernet + 2 Gigabit L2 Managed
Switch with Redundant Power 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
• Installing Optional 8-port FE TP/Fiber Modules and SFP Fiber Transceiver to
the L2 Managed Switch
Note: If you have no modules, please skip this section.
•Connecting the SFP Module to the Chassis:
The optional 8-port FE TP/Fiber Modules, Gigabit SFP modules are hot
swappable, so you can plug or unplug it before or after powering on.
1. Verify that the 8-port FE TP/Fiber Module, 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 (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in
10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and
crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) 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 the redundant 100-240 VAC, 50-60 Hz or –48VDC
power supply. The power supply will automatically convert the local AC/DC 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.
