COMPONENT OVERVIEW
Acme Packet 4500 Hardware Installation and Maintenance Guide 15
Alarm Active LED The alarm LED on the front control panel indicates if any alarms are active on the
Acme Packet 4500. The LED can be three different colors to indicate the severity of
the alarms.
• Unlit—system is fully functional without any faults
•
Amber—major alarm has been generated
• Red—critical alarm has been generated.
Alarm Silence Button The alarm silence button clears the alarm table internally and opens the alarm
circuits connected to the network interface unit’s alarm port.
Graphic Display The graphic display is a four-line VFD display window on the Acme Packet 4500’s
front control panel that reports real-time status, alarms, and general system
information.
Navigation Buttons You use the navigation buttons to navigate through the menus and information
visible on the graphic display.
Console Port The console port provides console access to the Acme Packet 4500 over a RS-232C
serial connection. It is logically identical to the rear console port; however only one
of the two console ports can be active at a time. See this chapter’s later "
Console
Port (17)" section for more information.
USB Port The USB port is reserved for software-enabled applications.
Intake Fans Four intake fans keep the Acme Packet 4500 cool by blowing air through the system
chassis. They are a part of the hot-pluggable fan module and are covered by a filter
that prevents excess dust and contaminants from entering the system. See this
chapter’s "
Fan Module " section for more information.
