Dahua DH-S5500-48GT4GF-AC Aggregation Switch

High Performance
DH-S5500-48GT4GF-AC all ports support wire speed forwarding, with
four GE uplinks ports onboard.
Virtualization technologies – IRF2
DH-S5500-48GT4GF-AC is pre-built with Intelligent Resilient Framework 2
(IRF2). IRF2 provides the following benefits:
• High scalability: With IRF2, plug-n-play device aggregation can be
achieved by adding one or more switches into the IRF2 stack and
enabling IRF2 stacking on the new device. New devices can be managed
with a single IP, and upgraded at the same time to reduce network
expansion cost.
• Load balancing: IRF2 supports cross-device link aggregation, upstream
and downstream can be connected to more than one physical link, which
creates another layer of network redundancy and boosts the network
resource utilization.
• Availability: DH-S5500-48GT4GF-AC Implements IRF2 through standard
Gigabit Ethernet (1GE) ports which allocates bandwidth for business and
application access and reasonably splits local traffic and upstream traffic.
IRF2 rules not only able to obey within and across the rack, but also
across the LAN.
Excellent manageability
The DH-S5500-48GT4GF-AC makes switch management with ease with
the support of SNMPv1/v2/v3, which can be managed by NM platforms,
such as Open View. With CLI and Telnet switch management is made
easier. And with SSH 2.0 encryption, switch management security is
enhanced.
Green Design
The DH-S5500-48GT4GF-AC implements a variety of green energy
saving features, including auto-power-down (port automatic energy
saving), if the interface status has been down for a period of time, the
system automatically stops the interface power and the system enters
power-saving mode. They also support EEE energy feature, by which
if a port stays idle for a period of time, the system will set the port to
energy-saving mode.
