Optional Redundant Power Supply
The DES-3326 24+2 Fast Ethernet Layer 3 Switch supports the optional DPS-1000 (Redundant Power
Supply) to provide automatic power supply monitoring and switchover to a redundant power supply
(located in the chassis of the DPS-1000) in case of a failure in the DES-3326’s internal power supply.
Fast Ethernet Technology
100Mbps Fast Ethernet (or 100BASE-T) is a standard specified by the IEEE 802.3 LAN committee. It is
an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at
100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
Ethernet protocol.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format,
and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a
tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold
increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet
environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s
existing investment in hardware, software, and trained personnel.
Gigabit Ethernet enables fast optical fiber connections and Unshielded Twisted Pair connections to
support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since
data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s
are able to perform 10 times the number of operations in the same amount of time.
