Modular Managed L2 Switch, (2) Power-Supply Slots


Please call 877-877-2269 for a replacement product or part.
Extended Double Diamond™ Warranty Available (3 Additional Year)


  • Easy to manage and configure.
  • Includes a single power-supply slot for a Power Supply Module (LB611C-AC, LB611C-DC, order separately).
  • Robust security with VLAN capabilities, as well as port security and IGMP snooping.
  • 802.1d Spanning Tree and 802.1w Rapid Spanning Tree enable you to configure the switch with a redundant backup path.
  • Virtual Stacking Management (VSM) enables you to manage up to 16 switches with one IP address.
  • 802.1x access control improves network security by enabling user authentication for each network access attempt.
  • Port mirroring enables you to use a protocol analyzer to track network errors or abnormal packet transmission without interrupting data flow.
  • The isolated group feature enables you to designate certain ports as protected.
  • Broadcast storm protection.
  • RoHS compliant.
  • Includes a 19" rackmount kit.

  • The Modular Managed L2 Switch is a versatile data center workhorse that features three slots, each supporting a hot-swappable 8-port copper or fiber Fast Ethernet module. The switch also has two dual-media ports that can support Gigabit Ethernet SFPs or function as a copper port.

    Fully manageable
    The switch is fully manageable through any standard Web browser over an IP network—even the Internet. It also supports SNMP v1 and v2 for easy integration into any managed network.

    Bandwidth aggregation
    MAC-based 802.3ad LACP Link Aggregation Control Protocol (LACP) enables you to bundle multiple ports to create a single high-bandwidth pipeline. You can set up two Fast Ethernet groups plus one Gigabit Ethernet group, with a per-group maximum of four ports. The switch can aggregate destination addresses (DA), source addresses (SA), or both. Link failover automatically shifts network traffic onto remaining ports if a port fails.

    802.1p Quality Of Service (QoS), helps to ensure that important network traffic gets through first. QoS enables you to set up to four priority levels so that, for instance, VoIP traffic gets priority over Web browsing. This feature prioritizes data at full wire speed and can operate based on strict priority, weighted round robin, or a mix of both.

    Q-in-Q VLAN for performance and security
    The VLAN feature in the switch offers the benefits of both security and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the broadcast traffic to within the same VLAN broadcast domain also enhances performance. VLAN support enabling advanced techniques such as "802.1Q-in-1Q" to be deployed. This product works with:
  • AC or DC Power Supply Modules (LB611C-AC, LB611C-DC)
  • 8-Port 10BASE-T/1000BASE-TX Module (LB620C)
  • 8-Port 100-Mbps Fiber Modules (LB621C–LB625C)
