Reliability
The AR750S-DP has dual hot-swappable AC or
-48V DC redundant power supplies packaged in
the 1RU rack mount chassis, provide the ultimate
in space saving, reliability and resiliency. The
AR750-DP can operate on just one PSU if
required. These features, combined with front-to-
back cooling, make the AT-AR750S-DP perfect for
the high-density rack environment where space is
at a premium.
Comphrehensive Management and
Configuration
The AR750 family comes with a comprehensive
suite of management features and is also
compatible with SNMP-based management
packages. Allied Telesis’ SNMP support extends to
SNMPv3 to provide secure management.
An extensive command set is available via the
Command Line Interface (CLI), and a browser-
based Graphical User Interface (GUI) is also
provided to simplify the configuration and
management of the routers. The GUI provides
access to default set-ups in key management areas
and provides access to regional settings.
WAN Load Balancing
The AR750 famalies’ WAN Load Balancer enables
the router to combine bandwidth from multiple
WAN connections for increased throughput,
redundancy and reliable WAN connectivity. When
a router simultaneously connects to multiple
WAN networks, the WAN load balancer will
distribute the traffic based on any one of a
number of selectable balancing algorithms. A typical
example would be a router that has two Internet
connections each exchanging data to remote sites
via different Internet providers. In this case an
outage limited to one network will not result in a
loss of connectivity to these sites.
