Description
SPUA is the core component for system control and
management and provides the management, forwarding, and
control planes. Meanwhile, both SPUA and SPUB have an
intelligent awareness engine (IAE) and provide intelligent
awareness service.
 Management plane: provides ports for configuration, test,
and maintenance and implements such functions as running
status monitoring, environment monitoring, log and alarm
processing, system loading, and system upgrades. It can use
the hard disk SM-HDD-SAS300G-A to record logs and
reports in real time.

Forwarding plane: parses and processes packets and
associates with other planes to forward, discard, or translate
packets.

Control plane: obtains user authentication information and
sends authentication results to the forwarding plane, so that
the forwarding plane can process packets based on user
information.

Intelligent awareness engine: is aware of the service of each
packet, parses the content to identify the application of the
packet as well as the file, virus, URL, email field, intrusion,
and attack information in the packet or flow, and provides
the forwarding plane with the detection result for further
processing.
SPUB has an IAE to provide content security. The CPU
resources of SPUB on the USG6680 are dedicated for the IAE.
Therefore, USG6680 has a higher performance than other USG
products.
The interface card provides gigabit and 10-gigabit electrical
and optical ports. The interface card is installed before
shipment and can be moved to another slot. The interface card
is not hot-swappable.
Expansion slots are reserved for expansion cards to provide
more ports or functions.
expansion cards.
Two DC or AC power modules are mandatory to provide 1+1
power redundancy. If one power module fails, the other can
support the entire system so that you can replace the faulty
power module without interrupting device operation.
The fan module provides air flow for heat dissipation. The fan
module supports hot-swapping and can be replaced without
interrupting device operation. However, to prevent
overheating, do not operate the device without a functioning
fan module for more than one minute.
