Product description

Management
• • Simple Web Management
  Allows for easy management of the switch-even by nontechnical users-through an intuitive Web GUI; supports HTTP and HTTP Secure (HTTPS)
  • SNMPv1, v2c
  Enables devices to be discovered and monitored from an SNMP management station
  • Port Mirroring
  Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
  • Dual Flash Images
  Provides independent primary and secondary operating system files for backup while upgrading
  • Network Time Protocol (NTP)
  Synchronizes timekeeping among distributed time servers and clients; keeps timekeeping consistent among all clock dependent devices within the network
  • Manual Network Time Configuration
  Manually set the date and time on the switch in the absence of an NTP server
  • Default DHCP Client Mode
  Allows the switch to be directly connected to a network, enabling plug-and-play operation; in absence of a DHCP server on the network, the switch falls back to a default, fixed IP address

Quality of Service (QoS)
• • Traffic Prioritization
  Provides time-sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p classification; packets are mapped to eight hardware queues for more effective throughput
  • Broadcast Control
  Allows limiting of broadcast traffic rate to reduce unwanted network broadcast traffic
  • IEEE 802.1p/Q
  Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q Virtual LANs (VLANs)

Connectivity
• • Auto-MDI/MDIX
  Automatically adjusts for straight-through or crossover cables on all ports
  • IEEE 802.3X Flow Control
  Provides a flow throttling mechanism propagated through the network to prevent packet loss at a congested node
  • Loop Protection
  If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms.
  • IEEE 802.3at Power over Ethernet (PoE+)
  Provides up to 30W per port, which allows support of the latest PoE+-capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3af- compliant end device; lowers the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments
  • PoE+ Port Availability
  Ports 1 - 12 provide PoE+ power
  • Auto PoE Power Configuration
  The switch automatically assigns the required power to a port for a PD device based on LLDP (Link Layer Discovery Protocol). Optionally, the switch permits manual, per port, PoE power configuration.
  • PoE Shut Down Mode
  A PoE scheduler provides the ability to define the hours of PoE power being supplied on a group of switch ports based on a 24-hour day. The scheduler enables the flexibility to select individual days of a week as well as recurrence on a weekly basis with a start and end date
  • Energy Efficient Ethernet
  Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity.
  • Auto Port Shut-Down
  The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link detection
  • Energy Efficient Cooling
  Includes a variable speed fans operating only at the speed necessary to maintain operating temperature to reduce excess noise and power consumption by the switch
  • Energy Savings Status
  The switch provides an estimated cumulative energy savings due to green Ethernet features enabled

Security
• • Secure Socket Layer (SSL)
  Encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.
  • Automatic Denial-of-Service Protection
  Monitors nine types of malicious attacks and protects the network by blocking these attacks
  • Management Password
  Provides security so that only authorized access to the Web browser interface is allowed

Performance
• • Half- and Full-Duplex Auto-Negotiating Capability on Every Port
  Doubles the throughput of every port
  • IGMP Snooping
  Improves network performance through multicast filtering, instead of flooding traffic to all ports

Layer 2 Switching
• • VLAN Support and Tagging
  Supports up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between workgroups
  • Jumbo Packet Support
  Improves the performance of large data transfers; supports frame size of up to 9220 bytes

Resiliency and High Availability
• • IEEE 802.1D Spanning Tree Protocol (STP) and IEEE 802.1W Rapid Spanning Tree Protocol (RSTP)
  Provides redundant links while preventing network loops
  • Link Aggregation
  Brings together groups of ports automatically using Link Aggregation Control Protocol (LACP) or, manually, to form an ultra-high-bandwidth connection to the network backbone; helps prevent traffic bottlenecks; and supports 16 trunks. This 24-port switch also supports up to 8 ports per trunk.

Ease of Use
• • Locator LED
  Allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches
  • Comprehensive LED Display with Per-Port Indicators
  Provides an at-a-glance view of status, activity, speed, and full-duplex operation.

Flexibility
• • Flexible Installation
  Allows mounting on wall, desktop, or under-table with supplied hardware
  • Rack Mountable
  All models include rack-mounting hardware for mounting in a standard 19-inch telco rack.
