Table 2-59 Functions of the USG6650/6660 components
Name Description
SPUA (the main
processing unit) SPUA is the core component for system control and
management and provides the management, forwarding, and
control planes and an intelligent awareness engine.
l 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, SM-HDD-SAS600G-
A or SM-HDD-SAS1200G-A to record logs and reports in
real time.
l Forwarding plane: parses and processes packets and
associates with other planes to forward, discard, or translate
packets.
l 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.
l 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.
Interface card
(mandatory) 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 slot Expansion slots are reserved for expansion cards to provide
more ports or functions.
Table 2-60 lists the supported
expansion cards.
Power module By default, the USG6650 has two AC power modules and does
not support DC. By default, the USG6660 has two DC or AC
power modules for 1+1 power redundancy so that if one power
module is faulty, it can be hot-swapped.
Fan module 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.
Filler panel Ensures normal air flow and keeps out dust.
Ports
The SPUA provides the following fixed ports:
