7-ii Tandberg Viking FS-1600 Series NAS Hardware User Manual
Event Viewer
An administrative tool that is used to view and manage logs of system,
program, and security events on your NAS. The Event Viewer displays five
types of events:
• Error
An error log describes a significant problem that has occurred, such
as a loss of data or loss of functionality.
• Warning
A warning log indicates a potential problem in the future.
• Information
An information log describes operation of an application, driver, or
service.
• Success audit
A success audit event is a user’s successful attempt to log on to the
NAS.
• Failure audit
A failure audit log is a failure to access a network drive.
Hub
A switching device through which a number of devices (such as computers)
can be connected to a network. Since connected devices are arrayed with
the hub at the center, this type of connection is referred to as a star topology.
Most hubs used with the Internet are equipped with a signal amplifier
(repeater) to support physical extensions.
IP address
An identifier used to indicate the addresses of devices (such as computers)
that are connected to a network. Because this identifier is used to designate
a particular destination during data exchange, each IP address must be
unique. The address consists of four period-delimited fields, each field being
a number from 0 to 255.
LAN (Local Area Network)
A network encompassing a relatively limited area, such as a building, a floor,
an organization, or a company.
LED (Light-Emitting Diode)
A diode that emits light and is used as a status indicator.
Log
A record of events occurring during operation, along with their times of
occurrence, or the file containing such a record. For example, an error log
contains a list of errors occurring in the NAS appliance, while an access log
records access to the NAS appliance.
