1. Introduction
1-1. Overview of the switch
The 48-port Gigabit L2 Managed Switch is a L2 management switch that
meets all IEEE 802.3/u/x/z Gigabit, Fast Ethernet specifications. The switch has 44
10/100/1000Mbps TP ports and 4 Gigabit TP/SFP transceiver slots. It supports
console, telnet, http and SNMP interface for switch management. 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, IGMP Snooping capability via the intelligent software. It is
suitable for both metro-LAN and office application.
In this switch, Port 45 to Port 48 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.

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 3-22 for more details.
The switch will not stop operating while upgrading firmware and after that, the
configuration keeps unchanged.
