Great Fault-Tolerance
Spanning tree is a link management protocol that provides
path redundancy while preventing undesirable loops in the
network. ES4512C delivers not only IEEE802.1D protocol
(Spanning Tree), but also Accton proprietary Fast Mode
Spanning Tree, IEEE802.1s (Multiple Spanning Tree) and
IEEE802.1w (Rapid Spanning Tree). Besides of Spanning
Tree for Fault-Tolerance, ES4512C also provides a redun-
dant power supply inlet in the rear panel for power-fault-tol-
erance to ensure a reliable system.
Advanced Network Security Mechanism
As networks grow and branch out to remote locations, net-
work security increases in importance and administration
complexity. Customers need to protect networks and net-
work services from unauthorized access by remote users.
The Accton ES4512C provides multiple security algorithms
such as Port Security, SSL, Web management Encryption,
RADIUS and TACACS+ to protect data communication to
ensure data privacy.
Eliminate Network’s Bottleneck
To secure the bandwidth for highly bandwidth demanded
traffic, ES4512C offers not only basic IEEE 802.3ad Link
Aggregation, but also Cisco’s EtherChannel for static trunk.
Users can choose the way they prefer or used to configure
the system. This is a user-friendly design to meet custom-
er’s preference.
Great Performance
The Accton ES4512C offers high performance at a very
attractive price. It boost layer-2 switching performance and
eliminates network bottlenecks with wire-speed switching
capability. In addition to wire-speed switching, it also offers
rich software feature sets to manage and secure the whole
network communication.
ES4512C L2/L4 Gigabit Ethernet
Standalone Switch
The Accton ES4512C is a high performance managed L2/L4 Gigabit switch that provides an
T
ideal solution for Enterprise Gigabit applications. With 8 10/100/1000Mbps Gigabit Ethernet
ports plus 4 Combo ports with full L2/L4 features, the ES4512C is designed to meet the needs of
the most demanding departmental and Enterprise connectivity applications.
TheAccton ES4512C is a high-density Gigabit Switching system with compact design, in 1U
height, and reliable performance. This cost effective, intelligent Gigabit switch is fully manageable, making it a good choice for networks of the biggerrprise size. The switch optimizes and
controls data flow through the use of advanced quality of service and security algorithms, helping to ensure that mission-critical traffic reaches the intended users securely every time.
