Provides power across unshielded twisted-pair wiring to devices attached to its six standard PoE 10/100/1000-Mbps copper ports. Also has two dual-media port interfaces, each of which can be used as either an extra copper 10/100/1000 PoE port or for adding a 1000-Mbps fiber uplink (optional SFP required). Copper ports autonegotate for speed and feature Auto-MDI-X for crossover or straight-through cabling. Fully compliant with IEEE 802.3/u/x/z/ab/af standards. Manageable via an Ethernet or a Web-based connection associated with an SNMP agent. VLAN and QoS prioritization features. Supports Layer 4 TCP/UDP port and ToS classifications with four internal priority queues. Supports LACP port trunking with up to four trunking groups for each group. Autodetects powered device and consumption levels, and supports per-port consumption monitoring. Enables you to manage bandwidth ingress and egress rates per port. Broadcast/multicast storm suppression restricts excess traffic by port. Port mirroring for monitoring traffic ingress on a port without interrupting data flow. Configure redundant backup bridge paths with 802.1w/802.1s/802.1d spanning tree capabilities. Supports 802.1x access control, IP MAC binding, and management access policy controls. Circuit protection prevents power interference between PoE ports. RoHS compliant.
This managed Ethernet switch provides IEEE 802.3af power plus high-speed Gigabit throughput to network devices within a workgroup or LAN edge application.
Operating as an end-span Power over Ethernet (PoE) device, the PoE L2 Managed Gigabit Switch is ideal for smaller PoE applications where you want to provide and allocate bandwidth for VoIP and security cameras located in areas without easy access to AC power.
In addition to six standard-configuration copper 10-/100-/1000-Mbps RJ-45 ports (Ports 1–6), the switch features two dual-media port interfaces (Ports 7–8), presented as two copper 10/100/1000 RJ-45 ports and two Small Form-Factor Pluggable (SFP) optical transceiver slots.
Use the dual-media interfaces to attach additional copper PoE devices to the RJ-45 ports or to plug in compatible SFPs for fiber-based Gigabit uplinks. SFPs are available for your required fiber type, mode, connector, and distance (contact our FREE Tech Support for all our SFP choices). You can even mix copper RJ-45 links with fiber SFP links on Ports 7–8.
The PoE L2 Managed Gigabit Switch gives you non-blocking, wire-speed switching performance with 16 Gbps of switch capacity, supports 8K MAC addresses, and offers 9K jumbo frame support.
With SNMP support, the PoE L2 Managed Gigabit Switch can be managed easily from an IP network. Even better, using Virtual Stacking Management (VSM), you can "stack" up to 16 switches and manage them all via a single IP link. Because it's a virtual distributed configuration, no stacking hardware is required.
Centralized, smart power distribution
By using Power over Ethernet, you can centralize power distribution without additional infrastructure to supply power—no need for any nearby power outlets.
As a PoE end-span device, the switch provides a total of 65 watts of power over copper cable, distributing 48-VAC power across the copper pairs to each individual PoE-compliant end device.
The power draw of each device will determine how many devices can be connected to the switch at any one time. The switch has a total of 65 watts to give out. For example, if your PoE devices require 15.4 watts of power a piece, then you can attach only four devices to the switch. However, if the PoE devices require just 7.7 watts of power, then eight of the devices can be attached to all eight ports on the switch.
The PoE L2 Managed Gigabit Switch also prevents power on one port from interfering with power on the other ports, comes with smart power management features, and supports per-port consumption monitoring. It autodetects device and consumption levels, and determines the length of the cable to a PoE client (as well as if the client is idle), providing the appropriate level of PoE power to the devices automatically.
Management, redudancy, and security features
Full SNMP v.1 and v.2 support makes the PoE L2 Managed Gigabit Switch easy to integrate into any managed network. With an SNMP agent, you can log on to the switch to monitor, configure, and control each port's activity in a user-friendly way over an IP network.
Additionally, the PoE L2 Managed Gigabit Switch supports MAC-based 802.3ad Link Aggregation Control Protocol (LACP) for increased redundancy and higher availability.
You can combine Gigabit ports to create a multilink, load-sharing trunk. The switch supports four trunking groups, and up to four Gigabit ports can be set up per trunk, providing up to 8 Gbps of bandwidth. The switch also balances the traffic load, aggregating all traffic based on MAC addresses.
What's more, you can configure a redundant backup bridge path to guarantee the transmission and reception of packets on a network, as well as isolate groups to protect certain ports while leaving other ports non-isolated. In this configuration, traffic can only be sent from isolated group to non-isolated group.
Plus, port mirroring helps you to track network errors and abnormal packet transmission by forwarding a copy of each incoming and outgoing packet to another switch port where you can examine it with a protocol analyzer.
Also, to keep broadcast, multicast, and unknown-unicast traffic from flooding your network, the PoE L2 Managed Gigabit Switch features broadcast/multicast storm control, which enables you to set threshold values and control the rate limit for each port.
For securing network access by network devices, the PoE L2 Managed Gigabit Switch boasts IEEE 802.1x access control for port-based and MAC-based authentication. Each network access attempt requires user authentication.
In addition, you can limit the number of MAC addresses per port to control the number of stations for each port, as well as define static MAC addresses for each port to help ensure access only by registered machines.
QoS and VLAN Q-in-Q support, too
The switch boasts a QoS Control List (QCL) with four internal priority queues, enabling you to provide prioritization and lower latency where it's most required. Using Layer 4 TCP/UDP port and ToS classification, the PoE L2 Managed Gigabit Switch classifies packets as different priorities. This feature makes it particularly ideal for switching packets in real-time, delay-sensitive VoIP applications.
The PoE L2 Managed Gigabit Switch supports up to 4000 VLAN entries. Additionally, a Q-in-Q feature for subscriber aggregation enables you to boost both VLAN security and performance by using double VLAN tags.
You can isolate traffic between different users and limit broadcast traffic to within the same VLAN broadcast domain. For instance, you can create and maintain private VLANs for separate departments within the structure of your wide-area VLAN.
