COMPONENT OVERVIEW
Version 1.0 Acme Packet, Inc. Technical Publications 23
The Net-Net 6300 automatically adjusts fan speed based on the current operational
status and environmental conditions. Fan speed regulation is an automated process
that requires no user intervention. You can monitor the status of the fan speed from
the Environment menu of the graphic display.
If the Net-Net 6300 experiences a fan module malfunction and generates an alarm,
you must remove the existing fan module and replace it with a fully functioning fan
module.There is a visible FAULT LED identifying the bad or malfunctioning Fan.
Air Filter
The Net-Net 6300 air filter removes airborne particles before they are drawn into the
system chassis.
Net-Net 6300 Hardware Architecture
The hardware architecture of the Net-Net 6300 series hardware architecture is
depicted below. The Net-Net 6300 series hardware is purpose built for SBC
applications and relies on state-of-the-art network processing and traffic
management components to deliver the necessary platform for delivering security
and scalable media processing.
The Network Processing (nP) subsystem is comprised of the network processors,
traffic management, and content addressable memory (CAM). This subsystem hosts
the media control module and is completely hardware based. Adjunct to the network
processing components are the QoS engine for monitoring bearer QoS metric.
The signaling processor subsystem is comprised of the host subsystem and
associated memory (noted in red in the diagram). The session control functions
including the session signaling layer, call routing and management elements are
hosted on the signaling processor subsystem.
The separation of signaling and media processing is absolutely necessary for the
following reasons:
• Guarantee media processing will never overwhelm signaling processing.
Signaling processing performance is not impacted by media processing load asit
is with single more monolithic solutions based on general purpose computing
platforms.
• Protection of the signaling processing subsystem for overload and DoS attacks.
When DoS attacks are detected, these attacks are policed and isolated in
hardware.
