What is OptiSwitch-2400/L3?
The OptiSwitch-2400/L3 is an IP router with the ability to provide
solutions for a wide range of networking applications. It includes a
twenty-four slot IP platform for both Enterprise, carriers, ISPs and
data service providers. The OptiSwitch-2400/L3 router performs
high-speed traffic engineering upto layer 4 and handles intelligent
communication between networks.

OptiSwitch 2400/L3 Introducing OptiSwitch-2400 L3
CHAPTER 1
3
What Can OptiSwitch-2400 Do for You?
The OptiSwitch-2400/L3 is a multi-faceted system that acts as a
switch router, IP security platform and network backbone. It is
capable of performing traffic engineering up to Layer 4 and
facilitating high-speed network connections for service providers.
The two principal functions of the OptiSwitch-2400/L3 are to
provide IP routing functionality, as well as, IP segmentation for
security and performance purposes.
Routing Function
The OptiSwitch-2400/L3 is capable of processing 35.7 million
packets per second. The router supports routing protocols such as
RIP I and II, OSPF,BGP4, together with functionality of networking
protocols and applications such as VRRP, DHCP, DHCP relay server
and DiffServ.
Backbone Management and Routing
The OptiSwitch-2400/L3 provides full routing functionality. With the
usage of the Linux based routing controller module and Layer-3
modules, high density routing interfaces can be provisioned in a
single system. The combination of a modular high-density and
powerful switch router with an extremely high capacity makes the
OptiSwitch-2400/L3 the ideal Enterprise backbone system. In the
enterprise LAN, the OptiSwitch-2400/L3 provide routing
functionality, as well as, IP segmentation for security and
performance purposes.
The OptiSwitch™ routing architecture is based on the system’s
powerful Layer 2-5 ASICs, which are capable of performing frame
header lookups at wire speed. This switch router hardware
components perform the IP traffic forwarding, while the routing
protocols are performed in the routing controller module. This
routing controller is based on the Intel architecture , which runs the
Linux Operating System. The Routing controller is connected to the
Forwarding components through the backplane matrix.
The routing architecture is such, that the routing tables are stored
in the Ingress port, which is the incoming port. The switching
engine’s hardware performs the forwarding of the frame to the
Egress (destination) port through the backplane matrix.

OptiSwitch 2400/L3 Introducing OptiSwitch-2400 L3
CHAPTER 1
4
When a topology change occurs, or when a new route is added
the frame is forwarded to the routing controller, which performs
the action based on the relevant routing protocol. The instruction
is then returned to the routing tables, which are stored in the
switching engines. Once an entry is learned the switching engine
performs the forwarding without the need to communicate with
the routing controller.
Benefits
The OptiSwitch-2400/L3 provides the following benefits:
■Low-Cost Solution:
●High-density IP router cost-effective unit.
●Concentration and aggregation of IP traffic platform
■Flexible and Multifaceted Solution:
●Twenty four slot chassis with integrated routing fabric and
management.
●Supports routing protocols OSPF, BGP4, and RIP
●Supports IP protocols VRRP, DHCP and DHCP relay
●Supports DiffServ (Quality of Service)
●Flow classification provided by a service-aware switch
router.
●Traffic management for thousands of active users.
●Custom IP filters for security and delay-sensitive applications.

(Dedicated Equipment Rooms, Equipment Closets or
the like) in Accordance with Articles 110-16, 110-17,
and 110-18 of the National Electrical Code,
ANSI/NEPA 70.
c. Input wiring to terminal block must be routed and
secured in such a manner that it is protected from
damage and stress. Do not route wiring past sharp
edges or moving parts.
d. A readily accessible disconnect device, with a 3 mm
minimum contact gap, shall be incorporated in the
fixed wiring.
e. A Listed circuit breaker suitable for protection of the
branch circuit wiring and rated 48V dc minimum must
