Switch Architecture
These switches employ a wire-speed, non-blocking switching fabric. This
permits simultaneous wire-speed transport of multiple packets at low latency
on all ports. These switches also features full-duplex capability on all ports,
which effectively doubles the bandwidth of each connection.
T
hese switches use 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.
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 from the switch
over the Ethernet cable without requiring its own separate power source.
This capability gives network administrators centralized power control for
devices such as IP phones and wireless access points, which translates into
greater network availability.
For each attached 802.3af-compliant device, the switch automatically senses
the load and dynamically supplies the required power. The switch delivers
power to a device using the two data wire pairs in UTP or STP. Each port can
provide up to 15.4 W of power at the standard -48 VDC voltage.
Independent overload and short-circuit protection for each port allows the
switch to automatically shut down a port’s power when limits are exceeded.
Network devices such as IP phones, wireless access points, and network
cameras, typically consume less than 10 W of power, so they are ideal for
Power-over-Ethernet applications.
