Product Features

  • Provides (44) 10/100/1000 Gigabit UTP ports, plus (4) dual-media UTP/SFP and (2) SFP ports that support 100/1000 Gigabit fiber speeds.
  • Management interfaces include HTTP/HTTPS, Telnet/SSH, SNMP, console port.
  • Configurable QoS parameters for prioritizing and managing traffic.
  • Port security, access management, authentication.
  • 802.3az Energy-Efficient Ethernet saves on power costs.

Details

  • Switching capacity of 96 Gbps.
  • Bundle ports using 802.3ad LACP aggregation.
  • IGMP for limiting bandwidth-heavy multicast traffic.
  • Ideal for video streaming, VoIP, and Wi-Fi client applications.
  • RADIUS based 802.1x network access control plus port security.
  • Supports up to 4K simultaneous VLANs.

  • The 48-Port Gigabit Ethernet Managed Switch features 44 fixed ports plus combination UTP/SFP slots for additional connectivity as well as the management and security you need for your SMB or enterprise network. Plus, you can switch packets efficiently for real-time applications.

    This capable Layer 2+ switch includes 44 autonegotiating 10-/100-/1000-Mbps RJ-45 Ethernet ports and four dual-media ports (each of which consists of an 100-/1000-Mbps RJ-45 port plus an SFP port). The dual-media ports can be used either as a normal UTP Ethernet port or adapted to 100- or 1000-Mbps fiber through the use of an SFP.

    Ideal for mixed-speed and legacy-integration environments, the switch enables you to connect twisted-pair Ethernet, Fast Ethernet, and Gigabit Ethernet segments to devices on other ports or to a fiber optic backbone plugged into the switches' SFP slots.

    You can also bundle multiple ports to create a single high-bandwidth port using 802.3ad LACP aggregation. The switch supports up to eight ports per group and up to 24 groups total. Combine Gigabit ports, for instance, to create a multilink trunk for load sharing. It's especially beneficial in switch-to-switch cascading applications where you require higher full-duplex speeds.

    The 48-Port Gigabit Ethernet Managed Switch supports 1024 multicast groups. Broadcast/multicast/unicast storm control enables you to restrict excess traffic on your network. IGMP (v1/v2/v3) for limiting bandwidth-heavy multicast traffic.

    What's more, it has IPv6 support for newer networking equipment (delivering IPv6 multicast packets only to the required receivers).

    You can also control the rate limit for each switch port and set threshold values for the size of discarded packets. Jumbo frame support on the Gigabit interfaces helps to ensure reliable data transmission, too. With this, you can set the switches to forward packets up to 9K in size before discarding them.

    Fully manageable
    The integral Web server enables Web-based management via Web browser. This GUI interface enables switch configuration, system dashboard, maintenance, and monitoring.

    The switch is fully managed, supporting SNMP version 1, 2c, and 3. The embedded RMON software agents support RMON groups 1 (history), 2 (statistics), 3 (alarms), and 9 (events). For easy deployment, LLDP/LLDP-MED features aid the switch in discovering neighboring devices on a network.

    The wide range of management and support features also includes dual-image (primary and secondary) OS file backup, port mirroring for analysis, industry-standard sFlow® switched network monitoring, UPnP® for ease of device-to-device interoperability, and cable diagnostics.

    Support for VLANs and QoS
    The switch supports up to 4000 simultaneous VLANs for isolating guest traffic from your critical corporate network traffic. You can segment traffic with port-based, 802.1Q tag-based, or MAC-based VLANs.

    Plus, you can also program higher-layer classification and prioritization for reliable Quality of Service (QoS).802.1p Layer 2 QoS enables prioritization of time-sensitive applications, such as VoIP and video.

    Highly secure
    You get enterprise-class security features, too. In addition to the switch's VLAN support, it boasts 802.1X port-based network access control for authenticating devices connecting to your network.

    In addition, the switch supports SNMPv3 cryptographic security, SSH, and SSL for remote management via a connection that encrypts the packet content at each session. And by using its extensive ACLs (up to 256 entries total), you can keep guests or unauthorized users from accessing sensitive portions of your network.

    Green
    The 48-Port Gigabit Ethernet Managed Switch features IEEE 802.3az energy-efficient Ethernet, which scales down power consumption during periods of low data activity. This feature adds energy savings of up to 50%.

    Plus, cable length detection adjusts signal strength to the cable length, reducing power consumption on shorter cable runs.

    What's included:
    • 48-Port Gigabit Managed Switch
    • (1) AC power cord
    • (1) 19" rackmount kit
    • (1) DB9 to RJ-45 console cable
    • (1) CD-ROM with user manual
