Optional Redundant Power Supply

The VH-2402-L3, 24+2 Fast Ethernet Layer 3 Switch

supports the optional Redundant Power Supply to

provide automatic power supply monitoring and

switchover to a redundant power supply (located in the

chassis of the Redundant Power Supply) in case of a

failure in the VH-2402-L3's internal power supply.

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 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.
