Safety regulations
The safety regulations and observance of the technical data serve to
ensure trouble-free operation of the device and protection of persons and
material. It is therefore of utmost importance to observe and compliance
with these regulations.
If these are not complied with, then no claims may be made under the
terms of the warranty. No liability will be assumed for any ensuing
damage.
Safety of the device
This device has been manufactured in accordance with the latest
technological standards and approved safety regulations
The device should only be put into operation by trained and qualified staff.
Care must be taken that all cable connections are laid and fixed in position
correctly. The device should only be operated with the voltage supply
indicated on the identification label.
The device should only be operated by qualified staff or employees who
have received specific instruction.
If a device must be opened for repair, this should only be carried out by
employees with appropriate qualifications or by
hopf
Elektronik GmbH.
Before a device is opened or a fuse is changed all power supplies must
be disconnected.
If there are reasons to believe that the operational safety can no longer
be guaranteed the device must be taken out of service and labelled
accordingly.
The safety may be impaired when the device does not operate properly
or if it is obviously damaged.
CE-Conformity
This device fulfils the requirements of the EU directive 2014/30/EU
"Electromagnetic Compatibility" and 2014/35/EU "Low Voltage Equipment".
Therefore the device bears the CE identification marking
(CE = Communautés Européennes = European communities)
The CE indicates to the controlling bodies that the product complies with the
requirements of the EU directive - especially with regard to protection of health and safety for
the operator and the user - and may be released for sale within the common markets.

1 Board Description 7273 and 7273RC
The LAN Boards 7273 and 7273RC are Network Time Server (abbreviation NTS) for the use
in the modular
hopf
Systems 7001RC, 7001, 6844, 6844RC and 6855 and also in the non
modular DIN Rail Systems such as GPS Module 6875.
Generally the NTP/SINEC H1 LAN boards 7273 and 7273RC provide
functions and fields of applications completely backward compatible to the
boards 7271 and 7271RC.
The boards 7273 and 7273RC can be used as direct replacements for
already supplied boards 7271 or rather 7271RC. The successor boards
provide all functions, adjustment options and protocols as offered by the
boards 7271 and 7271RC.
The successor boards are suitable for extensions of
hopf
Clock Systems,
already operating boards 7271 or rather 7271RC (mixed operation) without
problems.
The boards 7273 and 7273RC are equipped with Ethernet interface (ETH0) 10/100 Base-T
(autosensing).
The boards 7273 and 7273RC supports operation in IPv4 and IPv6
networks.
The boards 7273 and 7273RC can be used by networks for highly accurate synchronisation
over NTP (Network Time Protocol) which is available worldwide.
The following synchronisations protocols are available:
•NTP (including SNTP)
•SINEC H1 time datagram
•Daytime
•Time
The network connection of the LAN boards 7273 and 7273RC can be installed at any desired
point on the network. Each board 7273/7273RC is a completely independent NTP Time
Server.
Depending on the respective
hopf
system, a number of these LAN Boards can be
implemented (even subsequently) in the Base System on a modular basis.
A variety of management and monitoring functions are available (e.g. SNMP traps, E-mail
notification, Syslog messages).
Increased security is freely available via optional encryption methods such as symmetric keys,
Autokey and access restrictions and the disabling of unused protocols.

Extensive parameters are provided to suit the conditions of individual applications by means
of a variety of access / configuration channels.
•Depending on the clock system the accessibility of the LAN boards 7273 or 7273RC
can be adjusted in the network via the keyboard of the
hopf
base system or via a
hmc
remote connection.
•The boards are completely configured over Ethernet by means of a web browser:
oHTTP/HTTPS WebGUI (Graphical User Interface)
oOr text-based menus over Telnet and SSH
•Various protocols (e.g. IPv4, http, https, Telnet etc.) are available for the Ethernet
connection.
The Board 7273(RC) currently has unlockable features that are described in Chapter 2.6
Activation of Functions (Activation Key):
•IEEE 802.1Q Tagged VLAN
Some basic features of the boards:
Time Protocols
•NTPv4 Server
•NTP Broadcast Mode
•NTP Multicast Mode
•NTP Client for additional NTP Servers (redundancy)
•SNTP Server
•NTP Symmetric Key Encryption
•NTP Autokey Encryption
•NTP Access Restrictions

1.1 Differences between the Boards 7273 and 7273RC
The board 7273RC is identical in function to the board 7273 but designed for the use in System
7001RC. For this purpose the board 7273RC additionally provides "Hot-Plug" and appropriate
internal interface functionality for the operation in a
hopf
7001RC Base System.
The boards 7273 and 7273RC should only be operated in the suitable Base
Systems.
The board 7273RC only works in a System 7001RC.
As the boards 7273 and 7273RC are identical in their most important
functions, the designation 7273(RC) is used in this manual unless there is
no different function of the boards.
In case a function is only provided by one of the two boards just the
designation of the appropriate board is used.

1.2.2 MAC Address for ETH0
Each LAN interface is uniquely identifiable in the Ethernet by means of a MAC address
(hardware address).
The MAC address assigned for the LAN interface ETH0 can be read in the WebGUI of the
appropriate board or determined by means of the
hmc
Network Configuration Assisant .
A unique MAC address is assigned for each LAN interface by
hopf
Elektronik GmbH.
hopf
Elektronik GmbH MAC addresses begin with 00:03:C7:xx:xx:xx.
