SV8100 PoE Gigabit Switch
The NEC PoE Gigabit Switch card (GSWU) is a fully managed switch which brings
gigabit speeds to users while adding a whole new level of intelligence and security to
networks.
The eight 10/100/1000 Mbps ports enable users to take advantage of the Gigabit
Ethernet interfaces. The NEC PoE Gigabit Switch Card supports the Univerge
SV8100 and SV8300 systems.
All user ports can support up to Gigabit Ethernet and may support the primary Layer 2
protocols also, with an emphasis on QoS features such as 802.1p and Diffserv.
The CD-ETIA blade has 8 RJ45 ports for 10BASE-T, 100BASE-TX and 1000Base-T
along the front. The CD-ETIA design is based on one card and one software build.
However, all the cards in the system are managed as a Master/Slave configuration.
The Master provides full distributed Layer 2 management to all Ethernet Switch cards
in the system.
The CD-ETIA can be a standalone blade providing 8 Gigabit Ethernet PoE ports.
However, the real advantage with this blade is that additional blades can be "stacked"
by external "daisy chain" connections to provide up to 76 contiguous ports (all on the
same managed domain/network). Below are the primary features of the card set.
Switches, unlike hubs, use microsegmentation to create collision domains, one per
connected segment. This way, only the Ethernet devices which are directly connected
via a point-to-point link, or directly connected hubs are contending for the medium.
By eliminating collisions, full-duplex point-to-point connections on the switch are
possible.
When multiple blades requiring Ethernet data connections are installed in a
UNIVERGE SV8100 chassis, the CD-ETIA can provide a neat and simple installation.
The CD-ETIA is an in-skin, fast Ethernet switching hub unit that provides the following
