Overview
GS-2148L, a 48-port Gigabit L2 Managed
Switch, is a standard switch that meets all
IEEE 802.3/u/x/z Gigabit, Fast Ethernet
specifications. The switch included 44-
Port 10/100/1000Mbps TP and 4-Port
Gigabit TP/SFP Fiber 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
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.
