Terms
This section provides related terms and definitions.
IP address
When Transmission Control Protocol / Internet Protocol (TCP/IP) is installed on a computer, an
Internet Protocol (IP) address is assigned to the system. Each address is unique and is made up of four
numbers, each between 0 and 256, such as168.8.156.210.
Network Management Proxy
Network Management Proxy is used to control a UPS and connect it to the TCP/IP network.
Network Management System
The Network Management System (NMS) supervises SNMP devices connected to the TCP/IP Network.
Network Shutdown Module
The Network Shutdown Module is a software module that uses the information transmitted by the Dell
Network Management Card/Proxy to inform computer users on the current status of the electrical power
supplied to the computer.
If the supply of the electrical power from the UPS is at risk, the Network Shutdown Module initiates an
orderly shutdown of the computer under the most secure conditions possible.
RSA Algorithm
An algorithm for public-key cryptography encryption protocol. An RSA key is the result of operations
involving prime numbers. RSA refers to Ron Rivest, Adi Shamir, and Leonard Adleman, who described
public-key cryptosystems in 1978.
Secure Socket Layer
The Secure Socket Layer (SSL) is a solution for securing transactions over the internet. SSL is a
communication protocol that authenticates the data exchanged, as well as ensuring its confidentiality
and integrity. The protocol uses a recognized encryption method, the RSA algorithm with a public key.
SSL is built into Internet Web browsers. The padlock in the bottom of your browser screen is
automatically displayed if the server sending information uses SSL.
Transmission Control Protocol / Internet Protocol
TCP/IP is a family of network and communication protocols for the transport and network layers. Also
known as the Internet Protocol suite of network communication protocols.
