Dynamic Host Configuration Protocol
In order to configure PCs automatically, centralized and uniformly in a TCP/IP network, a dynamic assignment
of IP addresses is used. DHCP is utilized. The system administrator determines how the IP addresses are to be
assigned and specifies the time lapse over which they are assigned. DHCP is defined in the Internet standards
RFC 2131 (03/97) and RFC 2241 (11/97).

Electromagnetic Compatibility
Electromagnetic compatibility (EMC) means that an item of electric equipment functions without error in a
specified environment. The environment is not influenced in any impermissible way here.
ENC
Enumerated Status Controllable
ENS
Enumerated Status
ESD Protection
The ESD protection is the entirety of all means and measures for the protection of electrostatic-sensitive
devices.
Far End Fault Indication
Far End Fault Indication (FEFI) is a special setting of switches. It is always only possible to log a line interrup-
tion on the receive line. If a line interruption is detected, the link status of the line is changed. The status
change leads to deletion of the MAC address assigned to the port in the switch. However, outage of the
receive line from the aspect of the switch can only be detected in the receiver, that is, by the switch. The
receiver then immediately blocks the transmit line and signals the connection failure to the other device. The
FEFI setting in the switch triggers detection of the error on the receive line of the switch.

Fleeting Indication
Fleeting indications are single-point indications present for a very short time, in which only the coming of the
process signal is logged and further processed time-correctly.
Floating
Floating means that a free potential not connected to ground is generated. Therefore no current flows
through the body to ground in the event of touching.
