Управляем суич L2+ 20 х 100/1000X SFP + 4 x Gigabit TP/SFP + 4 x 10G SFP+

PLANET SGS-5240-20S4C4XR is a Layer 2+ Stackable Managed Gigabit Switch that provides high-density performance, Layer 3 static routing with 10Gbps uplink interfaces delivered in a rugged, strong case.

The administrator can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the 10G network efficiently. Besides, with 128 Gbps switching fabric, the SGS-5240 series can handle extremely large amounts of data in a secure topology linking to backbone or high capacity servers for ISP and enterprise VoIP, video streaming, and multicast applications.

  • 24 x 100/1000BASE-X SFP slots 
  • 4 x 10/100/1000BASE-T RJ45 copper interfaces, shared with Port-1 to Port-4
  • 4 x 10GBASE-SR/LR SFP+ slots, compatible with 1000BASE-SX/LX/BX SFP
  • RJ45 to DB9 console interface for switch basic management and setup
  • 1 x 10/100BASE-TX Management port 
Stacking Features:
  • IP Stacking: Connects with stack member via Gigabit TP, SFP and 10G SFP+ interfaces, Single IP address management, supporting up to 16 IP units stacked together
  • Hardware Stacking: Virtualized multiple SGS-5240 switch series stacked into one logical device, Connects with stack member via assigned 10G SFP+ interfaces, Single IP address stack management, supporting up to 6 hardware units stacked together, Stacking architecture supports redundant ring mode
IP Routing Features:
  • IPv4/IPv6 hardware static routing
  • Routing interface provides per VLAN routing mode
 Layer 2 Features:
  • Supports VLAN: IEEE 802.1Q tag-based VLAN, Provider Bridging (VLAN Q-in-Q, IEEE 802.1ad) supported, GVRP for dynamic VLAN management, Protocol-based VLAN, MAC-based VLAN, IP subnet-based VLAN, Voice VLAN
  • Supports Link Aggregation: 802.3ad Link Aggregation Control Protocol (LACP), Cisco ether-channel (static trunk)
  • Supports Spanning Tree Protocol: STP, IEEE 802.1D (Classic Spanning Tree Protocol), RSTP, IEEE 802.1w (Rapid Spanning Tree Protocol), MSTP, IEEE 802.1s (Multiple Spanning Tree Protocol, spanning tree by VLAN), Supports BPDU & root guard
  • Port mirroring to monitor the incoming or outgoing traffic on a particular port (many to one)
  • Supports G.8032 ERPS (Ethernet Ring Protection Switching)
  • Loop protection to avoid broadcast loops
  • Link Layer Discovery Protocol (LLDP)
  • Compatible with Cisco uni-directional link detection (UDLD) that monitors a link between two switches and blocks the ports on both ends of the link if the link fails at any point between the two devices
Quality of Service:
  • Input and output rate limit per port bandwidth control
  • 8 priority queues on all switch ports: IEEE 802.1p CoS/DSCP/IP Precedence, VLAN ID, ACL, Policy-based ingress and egress QoS
  • Supports IPv4 IGMP snooping v1, v2 and v3
  • Supports IPv6 MLD snooping v1 and v2
  • Querier mode support
