Switch Architecture

The switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

The switch uses store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

This switch includes two Gigabit combination ports with RJ-45 connectors and associated SFP slots. The optional SFP stacking transceiver enables up to eight units to be connected together through a 1 Gbps stack backplane. The switch stack can be managed from a master unit using a single IP address.

Power-over-Ethernet Capability

The switch’s 24 10/100 Mbps ports support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devices using wires in the connecting Ethernet cable. Any 802.3af compliant device attached to a port can directly draw power
