Robust Layer 2 Features
The XGS3-24042 & 24242 can be programmed for basic switch management functions such as port speed
configuration, port aggregation, VLAN, Spanning Tree Protocol, WRR, bandwidth control and IGMP snooping.
They also support 802.1Q tagged VLAN, Q-in-Q, voice VLAN and GVRP Protocol. The VLAN groups allowed
to be on the XGS3-24042 & 24242 will be maximally up to 256. By supporting port aggregation, the
XGS3-24042 & 24242 allow the operation of a high-speed trunk combined with multiple ports. It enables up to
128 groups for trunking with a maximum of 8 ports for each group.
Efficient Management
For efficient management, the XGS3-24042 & 24242 Managed Gigabit Switches are equipped with console,
Web and SNMP management interfaces. With their built-in Web-based management interface, the
XGS3-24042 & 24242 offer an easy-to-use, platform-independent management and configuration facility. The
XGS3-24042 & 24242 support standard Simple Network Management Protocol (SNMP) and can be managed
via any standard-based management software. For text-based management, the XGS3-24042 & 24242 can
be accessed via Telnet and the console port. Moreover, the XGS3-24042 & 24242 offers secure remote
management by supporting SSH connection which encrypts the packet content at each session.
Flexibility and Extension Solution
The XGS3-24042 & 24242 provide 100/1000Mbps dual speed SFP fiber combo ports and four 1/10Gbps
SFP+ fiber ports. Each of the SFP+ slots supports Dual-Speed, 10GBASE-SR/LR or 1000BASE-SX/LX.
Therefore, the administrator can flexibly choose the suitable SFP transceiver according to not only the
transmission distance, but also the transmission speed required. The distance can be extended from 550
meters to 2km (multi-mode fiber) or to 10/20/30/40/50/70/120 km (single-mode fiber or WDM fiber). They are
well suited for applications within the enterprise data centers and distributions.
Intelligent SFP/SFP+ Diagnosis Mechanism
The XGS3-24042 & 24242 support SFP/SFP+ DDM (Digital Diagnostic Monitor) function that greatly helps
network administrator to easily monitor real-time parameters of the SFP/SFP+, such as optical output power,
optical input power, temperature, laser bias current, and transceiver supply voltage.
AC and DC Redundant Power to Ensure Continuous Operation
The XGS3-24042 & 24242 are equipped with one 100~240V AC power supply unit and one empty power
supply slot for redundant DC power supply – XGS3-PWR150-48 installation, which supports -40 ~ -60V DC
power input. With XGS3-PWR150-48 DC power supply implemented, the XGS3-24042 & 24242 can be
applied as the telecom level device. A redundant power system is also provided to enhance the reliability
with either AC or DC power supply unit. The redundant power system is specifically designed to handle the
demands of high-tech facilities requiring the highest power integrity.
