Powerfully-combined 40Gbps Solution for High-capacity Networks
PLANET XGS-5240-24X2QR is a high performance Layer 2+ Stackable Managed Switch that meets the next generation Metro, Data Center, Campus and Enterprise network requirements. It supports IPv4/IPv6 Layer 3 static routing capability and abundant L2/L4 switching engine, and provides high-density 24 10G SFP+ and 2 40G QSFP+ fiber interfaces delivered in a 1U rugged case. Up to 4 switches with a total of 96 10G SFP+ slots can be stacked up, making the management of a high-capacity network and all-purpose applications easier and more flexible. 

Totaling 640Gbps Switching Capacity
The XGS-5240-24X2QR provides twenty-four 10Gbps SFP+ and two 40Gbps QSFP+ fiber interfaces. Each of the SFP+ slots supports Dual Speed, 10GBASE-SR/LR or 1000BASE-SX/LX and each of the QSFP+ slots supports native 40GBASE-SR/LR and four 10GBASE-SR/LR Ethernet modes. 

The administrator can flexibly choose the suitable transceivers according to the transmission distance or the transmission speed required extending the 1G/10G/40G networks efficiently. Besides, with 640Gbps switching capacity, the XGS-5240-24X2QR can handle extremely large amounts of data in a secure topology linking to backbone or high capacity servers where audio, video streaming and multicast applications are utilized.

Centralized IP Stacking Management
Positioned as the distribution or aggregation layer switch for large networks, the XGS-5240-24X2QR supports IP stacking function that helps network managers to easily configure up to 24 switches in the same series via one single IP address instead of connecting and setting each unit one by one. The IP stacking technology groups the XGS-5240-24X2QR switches together to enable centralized management through a single unit, regardless of physical location or switch type, as long as they are connected to the same local network.

High Reliability Hardware Stacking
Using two user specified QSFP+ ports or SFP+ ports to connect up to 4 switches in the same series and build a virtually logical facility, the XGS-5240-24X2QR gives the enterprises, service providers and telecoms flexible control over port density, uplinks and switch stack performance. The stack redundancy of the XGS-5240-24X2QR ensures that data integrity is retained even if one switch in the stack fails. You can even hot-swap switches without disrupting the network, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands.

AC and DC Redundant Power to Ensure Continuous Operation
The XGS-5240-24X2QR is equipped with one 100~240V AC power supply unit and one additional 36-72V DC power supply unit for redundant power supply. 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. 

IPv4 and IPv6 VLAN Routing for Secure and Flexible Management
To help customer stay on top of business, the XGS-5240-24X2QR not only offers ultra-high transmission performance, but also IPv4/IPv6 VLAN routing feature which allows to cross over different VLAN groups and IP addresses for the purpose of having a highly-secure, flexible management.

Robust Layer 2 Features
The XGS-5240-24X2QR can be programmed for basic switch management functions such as dynamic port aggregation, Multiple Spanning Tree Protocol (MSTP), L2/L4 QoS bandwidth control, IPv4 IGMP snooping and IPv6 MLD snooping. It also supports 802.1Q tagged VLAN, Q-in-Q, voice VLAN and GVRP Protocol. By supporting port aggregation, the XGS-5240-24X2QR allows the operation of a high-speed trunk combined with multiple ports.

With its built-in Web-based management interface, the XGS-5240-24X2QR offers an easy-to-use, platform-independent management and configuration facility. For reducing product learning time, the XGS-5240-24X2QR offers Cisco-like command via Telnet or console port so that users do not need to learn new command.

The XGS-5240-24X2QR supports standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based management software. Moreover, the XGS-5240-24X2QR offers secure remote management by supporting SNMPv3, SSH and SSL connection which encrypts the packet content at each session.

Enhanced Security
The XGS-5240-24X2QR offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network application. Their protection mechanism also comprises 802.1x Port-based and MAC-based customer and device authentication. As to private VLAN function, communications between edge ports can be protected to ensure customer privacy. The XGS-5240-24X2QR also provides functions of DHCP snooping, Option 82 and ARP guard, and Anti-ARP scanning so as to prevent IP from attacking and discarding ARP packets with invalid MAC address. The network administrators can now construct a highly-secure corporate network with considerably less time and effort than before.

Intelligent SFP Diagnosis Mechanism
The XGS-5240-24X2QR supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP+, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
