S
The purpose of a system ground is to provide a low impedance path to
ground for electronic noise, energy from lightning strikes, and potential
"differences of potential" between the different pieces of equipment at
an installation site. Electronic noise can range in frequency from just
above DC to well over 100 MHz. The energy in lightning is distributed
across a frequency range of 10 KHz to well over 100 MHz. Therefore, an
effective ground path for this "broad band" of energy has to be much
wider than the "narrow band" 60 Hz AC power utility ground
requirements.
T
Tables hold parameters for several related items. For example, you can
add several potential managers to the SNMP IP access table. Tables can be
displayed using the Web Interface, command line interface, and SNMP.
Topology is the physical layout of network components (cable, stations,
gateways, hubs, and so on).
Transparent routing refers to routing a datagram between disparate
address realms, by modifying address contents in the IP header to be valid
in the address realm into which the datagram is routed.
A trap is used within SNMP to report an unexpected or unallowable
condition.
Trivial File Transfer Protocol (TFTP) is a lightweight protocol for transferring
files that is like a simple form of File Transfer Protocol (FTP). A TFTP client is
implemented on the unit. Using the upload and download commands, the
unit can copy a file to or from a TFTP server. TFTP server software is
provided on the product CD-ROM.
U
Uploading a file means copying a file from a network device to a remote
server. In case of the unit, uploading means transferring a file from the
unit to a TFTP server. See also download.
Upstream means a data stream from the end users to the central part of
the network. See also downstream.
