Back-up System with Redundant
Design
The back-up concept is critical for a core switch
to keep the stability and reliability for whole
networking system. Optional redundant agent
module and power supply module will ensure
the network manager the single fault on the
agent and power won't shut down the whole
system.
Investment Protection
As the major benefit of the chassis switch, the
initial investment is relatively small due to you
can optimize the I/O ports to fit system's need.
As the system expand, system manager can
select from broad rang of optional I/O modules
to fit its environment. Use's initial investment
won't be wasted when the networking
environment changed.
ES4708 Gigabit Ethernet Routing
Switch
ES4708 is a 8 I/O slots Gigabit Ethernet Routing Switch. It has hot-swappable
I/O modules, 1+1 power supply. It reaches 160G backplane bandwidth. Besides,
ES4708 supports Jumbo frame up to 9K and supports up to 192 Gigabit ports.
High Performance
The ES4708 offers high performance at a very
attractive price. It boost layer-3 routing
performance and eliminates network bottlenecks
with wire-speed IP routing. In addition to wirespeed routing, it also supports high switching
bandwidth up to 160 Gbps.
Design of Passive Backplane
The design of passive backplane offers system
manager for trouble shooting and maintenance.
The errors or damages on the ASIC or active
components would be fixed by replacing the new
module quickly. System manager does not need
to send the whole box back to the supplier for
fixing.
ES4708 supports the following I/O modules:
(1)24 1000Base-T RJ45, (2)12 1000Base-X GBIC, (3)24 100Base-T RJ45, (4)1/2
10GBase-T XFP.
