Up to 24 10/100Mbps Ports
Each slave switch in the stack can have from 20 to 24 10/100Mbps ports. These ports support the NWay standard, auto-sense and negotiate between 10BASE-T/100BASE-TX and full/half-duplex.
Up to 4 switches can be stacked together. Users can add units to reach maximum 94 10/100Mbps ports per stack. Switches are stacked together through high-speed stack cables that provide multi-gigabit per second backplane, allowing the entire stack to perform as a single entity.
100Mbps Fiber Ports
Up to 2 100BASE-FX fiber ports can be configured in each switch to combine twisted-pair with fiber connections. Capable of running at full-duplex, these ports serve well in high electromagnatic interference environments, providing cable distances of up to 2 km.
1000Mbps Gigabit Ports
Up to 2 optional 1000BASE-SX Gigabit Ethernet ports can be installed in an expansion slot of the switch. With flow control and full-duplex support, these ports are capable of handling very large amounts of data in a secure topology. The Gigabit ports allow the switches to connect to a fiber backbone that links departments together, or to a high-power server providing simultaneous access to multiple clients.
Port Trunks for Aggregated Bandwidths
Up to 8 10/100Mbps ports can be combined into a trunk. Multiple trunks can be configured from a VLANs for Performance and Security switch or the stack. These trunks provide alternative high-bandwidth, full-duplex 1600Mbps switch-to-switch or switch-to-server connection.
VLANs for Performance and Security
The managed stack supports standard virtual LANs (VLANs) to extend the broadcast domain, segment network traffic and improve performance and manageability. This allows adds, moves and changes to be easily carried out. VLANs also provides security by limiting broadcast domains, traffic in different segments and subnets can be separated for maximum throughput and secure networking.
Flow Control Against Data Loss
In the full-duplex mode, the switches' embedded flow control provides a means to protect users against possible data loss during transmission on the network. When connected to a LAN adapter (in a server PC) that supports flow control, the switches send signals to the PC regarding buffer overrun during peak usage periods. The PC then delays transmission until the switch is ready again to accept new data.
SNMP Management, RMON Monitoring
A managed stack can be managed in-band from an SNMP management station, and on a LAN via an Internet web browser. SNMP and other MIBs are built-in, and the in-band station runs an SNMP standard network management program. Web-based management program is built into the switches. RMON monitoring is through built-in RMON MIBs.
