Avocent Network Device SPC420 - Manual (Page 417)

Appendices 397
OSCAR interface
The OSCAR interface is a tool that is built in to Avocent appliances and allows a user
connected to the local KVM port to display and change settings in a KVM switch. The
OSCAR interface also allows a local user to connect to target devices.
Power device
An Avocent or supported third party cascade device that allows the remote controlling of target
device power.
Positive hysteresis
Positive hysteresis is the unsigned number of counts subtracted from the raw threshold value,
which creates the re-arm point for all sensor thresholds that are greater than zero (0). A
positive hysteresis value of 0 indicates that any thresholds greater than zero do not contain
hysteresis.
PPP (Point to Point Protocol)
PPP is a set of industry-standard framing and authentication protocols included with Windows
NT Remote Access Service to ensure interoperability with third party remote access software.
PPP negotiates configuration parameters for multiple layers of the OSI (Open Systems
Interconnection) model.
SDR repository device
An SDR repository device is the logical management device that provides a sensor data
records (SDR) system interface, which in turn, provides a set of SDR storage and retrieval
commands.
Serial console appliance
Serial console appliance refers to a unit that allows serial sessions to a target device and is
supported by the DSView 3 software. Serial console appliances include the ACS console
server, the legacy CCM and CPS appliances and other units supported by plug-ins. The ACS
console server is supported by a plug-in; for detailed procedures and what DSView 3
operations the ACS console server supports, see the corresponding plug-in documentation for
detailed procedures.
Serial session
A serial session is a type of target device session in which the target device contains a serial
connection (typically a Linux server TTY port or a router) and is connected through a serial
console appliance. A Telnet Viewer connection exists between the DSView 3 software client
and the serial console appliance. The appliance converts the Telnet information to serial
information.
Server
A server is a computer or device on a network that manages network resources. For example:
• A file server is a computer and storage device dedicated to storing files. Any user on the
network can store files on the server.
• A print server is a computer that manages one or more printers.
