Features
- Twenty-four 10/100 switched RJ45 ports with auto medium dependent interface (MDI) and MDI crossover (MDI-X) cable detection.
- 802.at Power over Ethernet (PoE) ports offering up to 180W output, maximum of 30W per port.
- 4 mini Gigabit Interface Converter (mini-GBIC) slots for fiber and copper Gigabit Ethernet expansion (shared).
- Nonblocking, store-and-forward switching mechanism.
- Simplified QoS management enabled by advanced queuing techniques using 802.1p, differentiated services (DiffServ), or type of service (ToS) prioritisation schemes enhances the performance of real-time applications such as voice and video.
- Configuration and monitoring from a standard web browser with WebView management.
- Secure remote management of the switch via Secure Shell (SSH) and SSL secure channel network protocols.
- 802.1Q-based VLANs enable segmentation of networks for improved performance and security.
- Private VLAN Edge (PVE) for simplified network isolation of guest connections or autonomous networks.
- Automatic configuration of VLANs across multiple switches through Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP).
- Automatic port configuration through auto MDI/MDIX and 802.1ab with Link Layer Discovery Protocol (LLDP) and Universal Plug and Play (UPnP) support.
- User/network port-level security via 802.1X authentication and MAC-based filtering.
- Increased bandwidth (up to 8x) and added link redundancy with Link Aggregation Control Protocol (LACP).
- Enhanced rate-limiting capabilities provide control, including back pressure to control the rate at which data can flow into and out of a port.
- Multicasting, broadcasting, and flooding control.
- Port mirroring for noninvasive monitoring of switch traffic.
- Simple Network Management Protocol (SNMP) versions 1, 2c, and 3 and Remote Monitoring (RMON) support.
- Fully rack mountable using the included rack-mounting hardware.

Port mirroring |
Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port. A single session is supported. |
|
VLAN mirroring |
Traffic from a VLAN can be mirrored to a port for analysis with a network analyser or RMON probe. Up to 8 source VLANs can be mirrored to one destination port. A single session is supported. |
|
DHCP |
DHCP Options facilitate tighter control from a central point (DHCP server) to obtain IP address, autoconfiguration and DHCP relay |

Discovery: |
|
|
Bonjour The switch advertises itself using the Bonjour protocol. |
