1. Introduction
1-1. Overview of GSW-1291
12-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 10-Port
10/100/1000Mbps TP and 2-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.
In this switch, Port 11, 12 includes 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.
This PSE switch also complies with IEEE 802.3af, its advanced auto-sensing
algorithm enables providing power devices (PD) discovery, classification, current
limit, and other necessary functions. It also supports high safety with short circuit
protection and power-out auto-detection to PD.
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.
