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.

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.

2 System Behaviour of the Board 7273(RC)
In this chapter the behaviour of the boards in special operation phases is described.
2.1 Boot Process
The boot process of the board starts after turning on the Clock System the board is operated
in or rather after a reset of the board.
During the boot process the board booting its operation system and is therefore not available
via LAN.
The boot process is indicated via the Status LEDs on the front panel and lasts approx. 1-1.5
minutes.
2.2 NTP Regulating Phase (Stratum/Accuracy)
NTP is a regulation process. After start of the NTP services (automatically processed during
booting) the board requires a certain period of time (usually 5-10 minutes) until NTP is set to
the high accuracy of the Base System and reaches the optimized operation condition of
STRATUM = 1 and ACCURACY = High.
The decisive factors here are accuracy of the synchronization source and the appropriate
synchronization condition of the clock System.
2.3 Reset- (Default) Button
The board 7273(RC) can be reset or set to the factory default status by a reset button behind
the front panel of the board. The reset button is accessible with a thin objective through the
small drilling in the front panel.

2.3.1 Board Reset
A short pressing of the Factory-Default-Button (between 1 and 10 seconds) a reset is initiated
on board 7273(RC).
For the duration of pushing the reset button between 1-10 seconds the 3
status LEDs on the board (Operation/ERROR/Status last 24h) are all
rhythmically flashing in a 2Hz cycle.
Release of a Board Reset:
1. Press reset button until the 3 board LEDs rhythmically flashing in 2Hz cycle.
2. Maximum 5 seconds after release of the reset button a board reset is performed.
3. The operation LED flashes in 1Hz cycle Upload of the operation system of board
7273(RC) (the board is not yet operational).
4. The standard operation condition is reached again after approx. 1-1.5 minutes. This
is shown by the following behaviour of the 3 Status LEDs:
• Operation LED is on
• NTP LED is on
• Send LED flashes (not applicable for DIN Rail)
After a reset board 7273(RC) in only accessible again via LAN after
booting.
2.3.2 Set Board to Factory-Default-State (incl. LAN Parameter)
If the board is not accessible in the Ethernet after an invalid configuration (e.g. via the
Ethernet), the board 7273(RC) can be set to factory default status by pressing the reset button
for more than 10 seconds.
When pressing the reset button for more than 10 seconds the 3 LEDs on
the board (Operation/ERROR/Status last 24h) are all rhythmically flashing
in 5Hz cycle.
List of the Factory-Default Parameters see Chapter 9 Factory Defaults
of Board 7273(RC)
Pressing the reset button for more than 10 seconds the LAN parameters saved in the board
are deleted and the board is set to DHCP mode:
• IP 000.000.000.000
• Gateway 000.000.000.000
• Net Mask 000.000.000.000
All parameters modified via the reset button are not updated depending
on the Base System and thus not correctly indicated in the menu of the
Base System after default.
After the default the LAN parameters of the board 7272(RC) have to be
completely configured and entered via the Base System.

5. All configurations in WebGUI should be checked and may need to be reset.
2.4 Firmware Update
The board 7273(RC) is a multi processor system. For this reason a firmware update always
consists of a so called Software SET including two (2) programs versions for the image and
H8 programs defined by the Set-Version which both needed to be loaded into the board.
ATTENTION
In order to select the correct image update, Chapter 6.3.5.5.1 Select
Image Update must be checked!
An update is a critical process.
The device should not be turned off during the update and the network
connection to the device should not be interrupted.
All programs of a SET needed to be loaded to ensure a defined operation
condition.
The assignment of program versions of a SET-Version may be taken from
the Release-Notes of the software sets of board 7273(RC) in cases of
doubt.

3 Implementing Board 7273(RC) in a modular
hopf
19" Base System
Operation
An ESD conform handling and operation of the board has
to be ensured!
Otherwise there is the danger that the board might get damaged through
ESD (electrostatic discharge).
Damages to the board caused by improper handling are not covered by
factory guaranty.
Electrical Properties
The function board 7273 does not support Hot Plug.
A change of boards mandatorily requires turn-off of System. Otherwise
the System or the function boards might get damaged.
System Requirments
The boards 7273 und 7273RC are function boards for the system bus.
Thus the systems in which these boards should be operated needed to
provide appropriate slots.
Non-Modular Systems
DIN Rail Systems are non-modular Systems. The user cannot change
or extend boards to these systems.
Board Number
Each LAN Board is assigned a definite board number via DIP switch in
order to be uniquely identified in a
hopf
Base System.
Configuration
The basic LAN parameters (IP address etc.) to access the board 7273(RC)
in the network are set via the Base System or via the Network
Configuration Assistant integrated in the
hmc
.
Afterwards the complete parameterization of the board is made by means
of a web browser via WebGUI of the board.
Power Supply
The functions boards 7273 and 7273RC (except DIN Rail) are exclusively
supported with operating voltage via the internal system bus.

3.1 Handling of Board / ESD Protection
An ESD conform handling and operation of the board has
to be ensured!
Otherwise there is the danger that the board might get damaged through
ESD (electrostatic discharge).
Damages to the board caused by improper handling are not covered by
the factory guaranty.
3.2 General - Setting the Board Number for the Use in Base System
The boards must be coded to a System Board number in order to enable the various LAN
Boards to be administered and configured in the Base System.
Under no circumstances may two LAN with the same board number be
integrated into one Base System. This leads to unspecified faults on these
two boards!
The coding of the board number is effected on board 7273(RC) via DIP switch bank (DS1).

4 Network Configuration for ETH0 via LAN Connection
through
hmc
After connecting the system to the power supply and creating the physical network connection
to LAN interface of the board 7273(RC), the board can be searched for in the network via the
hmc
(
hopf
Management Console). Afterwards the base LAN parameter (IP address,
netmask and gateway) may be adjusted in order to allow accessibility of the board for other
systems in the network.
The SEACH Function of the
hmc
- Network Configuration Assistant
requires for location and recognition of the wished LAN board(s) the
hmc
-computer is in the same SUB Net.
The basis LAN parameters can be set via the
hmc
integrated Network Configuration
Assistant.
After a successful start of the
hmc
Network Configuration Assistant and completed search
of the
hopf
LAN Modules, the configuration of the base LAN parameters can be done.
The LAN boards are listed in the Device List as:
727300 - Board 7273 1U and 3U
727300DIN - Board 7273DIN-Rail
7273RC00 - Board 7273RC

The determination of different
hopf
LAN boards of the same type is made via Hardware
Address (MAC Address).
For an extended configuration (WebGUI) of the LAN board 7273(RC) via a browser the
following base parameters are mandatory:
• Host Name e.g. hopf7273
• Network Configuration Type Static IP Address
• IP Address e.g. 192.168.232.1
• Netmask e.g. 255.255.224.0
• Gateway e.g. 192.168.224.1
The hostname must meet the following conditions:
• The hostname may only contain the characters 'A'-'Z', '0'-'9', '-' and
'.'. There should be no distinction between upper-and lower-case
letters.
• The character '.' may only appear as a separator between labels in
domain names.
• The sign '-' must not appear as first or last character of a label.
The network parameters being assigned should be pre-determined with
the network administrator.

After entering the above mentioned LAN parameters they needed to be transferred to the LAN
board 7273(RC) via Button Apply . Afterwards the entry of the Device Password is
requested:
Device Password <device> is set for LAN
boards 7273(RC) on delivery. So no further
entry is required here – click on the
button OK to confirm.
The LAN parameters thus set are directly
adopted by the LAN board (without reboot) and
are immediately active.

5 Network Configuration for ETH0 via the Base System
The only configuration that is carried out on Board 7273(RC) via the Base System is to enable
it to be reachable on the network via ETH0. All other configurations on the Board are carried
out over the WebGUI.
LAN Board 7273(RC) is configured via the keyboard of the respective Base System. The
necessary network parameters are configured such as IP address, gateway address, network
mask and a general control byte.
The Technical Description of the respective Base System is the basis for configuration. The
following covers only the Board-specific menus of the respective Base System.
Not all Base System do accept LAN parameters which are changed via
the WebGUI and thus they are no longer displayed correctly in the Base
System. For this reason the assignment of LAN parameters via the Base
System is recommended. For the exact behaviour of the Base System the
appropriate manual should be considered.
IP Address (IPv4)
An IP address is a 32 bit value divided into four 8 bit numbers. The standard presentation is 4
decimal numbers (in the range 0...255) separated from each other by dots (dotted quad
notation).
Example: 192.002.001.123
The IP address consists of a leading network ID followed by the host ID. Four common network
classes were defined in order to cover different requirements. Depending on the network class,
the last one, two or three bytes define the host while the rest define the network (network ID)
in each case.
In the following text the "x" stands for the host part of the IP address.
Class A Networks
IP addresses 001.xxx.xxx.xxx to 127.xxx.xxx.xxx
There is a maximum of 127 different networks in this class. This allows the possibility to
connect a very high number of devices (max. 16.777.216)
Example: 100.000.000.001, (Network 100, Host 000.000.001)
Class B Networks
IP addresses 128.000.xxx.xxx to 191.255.xxx.xxx
Each of these networks can consist of up to 65534 devices.
Example: 172.001.003.002 (Network 172.001, Host 003.002)
Class C Networks
IP addresses 192.000.000.xx to 223.255.255.xxx
These network addresses are the most commonly used. Up to 254 devices can be connected.

Class D Networks
The addresses from 224.xxx.xxx.xxx - 239.xxx.xxx.xxx are used as multicast addresses.
Class E Networks
The addresses from 240.xxx.xxx.xxx - 254.xxx.xxx.xxx are designated as "Class E" and are
reserved.
Gateway Address
The gateway or router address is required in order to be able to communicate with other
network segments. The standard gateway must be set to the router address which connects
these segments. This address must be within the local network.
Network Mask
The network mask is used to partition IP addresses outside of network classes A, B and C.
When entering the network mask it is possible to designate the number of bits of the
IP-address to be used as the network part and the number to be used as the host part, e.g.:

6.2 General – Introduction
Board 7273(RC) should be accessible to a web browser if it has been set up correctly. Enter
the IP address - as set up on the Board earlier - or the DNS name on the address line
<http://xxx.xxx.xxx.xxx> and the following screen should appear.
When using IPv6, it is mandatory to enclose the IPv6 address with [ ]
e.g..: http://[2001:0db8:85a3:08d3::0370:7344]/
Configuration can only be completed via the Board’s WebGUI!
The WebGUI was developed for multi-user read access but not multi-user
write access. It is the responsibility of the user to pay attention to this
issue.

6.2.1 LOGIN and LOGOUT as a User
All of the Board’s data can be read without being logged on as a special user. However, the
Board data can only be configured or modified by an authorised user! Two types of user are
defined:
• "master" user (default password on delivery: <master> )
• "device" user (default password on delivery: <device> )
Differentiation is made between upper and lower case characters in the
password. Alphanumeric characters and the following symbols can be
used: . , ! " $ % & / { } [ ] ( ) = ? \ + - @ * ~ # ' < > | ; : _
The password should be changed after the first login for security reasons.
The following screen should be visible after logging in as a "master" user:
Click on the Logout button to log out. WebGUI is equipped with session management. If a
user does not log out, he or she is automatically logged off after 10 minutes of inactivity (idle
time).

After successful login, depending on the access level (device or master user), changes can
be made to the configuration and saved.
Users logged in as "master" have all access rights to Board 7273(RC).
Users logged in as "device" do not have access to:
• Trigger reboot
• Trigger factory defaults
• Carry out image update
• Carry out H8 firmware update
• Upload Certificate
• Change master password
• Diagnostics
• Download configuration files
6.2.2 Navigation via the Web Interface

6.2.3 Entry or Changing Data
It is necessary to be logged on as one of the users described above in order input or change
data.
After an entry has been made the configured field is marked with a star ' * '. This means that
a value has been entered or changed but is not yet stored in the flash memory. It is necessary
to be acquainted with the symbols shown below in order to be able to save the configuration
or the changed value.
Meaning of the symbols from left to right:
No.
Symbol
Description
1
Apply
Acceptance of changes and entered data
2
Reload

3
Save
Fail-save storage of the data in the flash configuration
For permanent storage the value MUST be accepted by the Board with Apply and then saved
with Save.
However, this data is then lost when the
hopf
Base System is switched off or restarted.

If the data is only to be tested it is sufficient to accept the changes with Apply.
Changing Network Parameters
Modifications of the network parameters (e.g. IP address) are immediately
effective clicking on Apply to confirm.
However, the modifications are not permanently saved yet. This requires
to access the WebGUI with the new network parameters again and to
save the data with Save permanently.
For adopting changes and entering values only the respective buttons in
the WebGUI can be used.
6.2.4 Plausibility Check during Input
A plausibility check is generally carried out during input.
As it can be seen in the above image, an invalid value (e.g. text where a number should be
entered, IP address instead of a range etc.) is identified by a red border when an attempt is
made to accept these settings. It should be noted here that this is only a semantic check and
not to test whether an entered IP address can be used on the network or in the configuration!
If an error message is displayed it is not possible to save the configuration in the Board’s flash
memory.
The error check only verifies semantics and the validity of ranges. It is NOT
a logic or network check for entered data.

6.3 Description of the Tabs
The WebGUI is divided into the following tabs:
• General
• Network
• NTP
• Alarm
• Device
6.3.1 GENERAL Tab
This is the first tab which is displayed when using the web interface.
NTP Time Status
This area shows basic information about the current time and date of the Board. The time
always corresponds to UTC time. The reason for this is that NTP always works with UTC and
not local time.
Stratum displays the actual NTP stratum value of the bard 7273(RC) (value range from 1-16).
The ACCURACY field (accuracy of NTP) contains the values LOW, MEDIUM and HIGH. The
meaning of these values is explained in Chapter 10.6 Accuracy & NTP Basic Principles and
Chapter 8 Technical Data.

6.3.2.1 Host/Nameservice
Setting for the unique network identification.
6.3.2.1.1 Hostname
The standard setting for the Hostname is "hopf7273". This name should also be adapted to
the respective network infrastructure.
In case of doubt, just leave the standard setting as it is or ask your network administrator.
The hostname must meet the following conditions:
• The hostname may only contain the characters 'A'-'Z', '0'-'9', '-' and '.'
. There should be no distinction between upper-and lower-case
letters.
• The character '.' may only appear as a separator between labels in
domain names.
• The sign '-' must not appear as first or last character of a label.
For a correct operation a hostname is required. The field for the hostname
must not be left blank.
6.3.2.1.2 Use Manual DNS Entries
With this setting you can select whether the manually entered DNS servers (DNS servers 1 to
3) should be used.
If "enabled" is selected here, the entries in DNS Server 1 to 3 are used.
If "disabled" is selected, the entries in DNS Server 1 to 3 are ignored.
If a DHCP server is used to distribute the network configuration and if this
also distributes the DNS servers used in the network, then Use Manual
DNS Entries should be set to disabled.
6.3.2.1.3 DNS Server 1 to 3
The IP address (IPv4 or IPv6) of the DNS server should be entered if you wish to use the FullyQualified Host Name (hostname.domainname) or work with reverse lookup
Contact your network administrator for details of the DNS server if not known.
If no DNS server is available (special case), enter 0.0.0.0 in the input field or leave the field
blank.

6.3.2.1.4 Use Manual Gateway Entries
With this setting, you can select whether the manually entered gateways (Default Gateway
IPv4 and Default Gateway IPv6) should be used.
If "enabled" is selected here, the entries in Default Gateway IPv4 and Default Gateway IPv6
are used.
If "disabled" is selected, the entries in Default Gateway IPv4 and Default Gateway IPv6 are
ignored.
If a DHCP server is used to distribute the network configuration and if this
also distributes the address of the default gateway used in the network,
then Use Manual Gateway Entries should be set to disabled.
6.3.2.1.5 Default Gateway IPv4
The standard gateway is generally configured via the Base System menu. However it can also
be changed via the web interface.
In Base System 7001 / 68xx the changed LAN configuration is only stored
in the Board’s flash memory and is ALWAYS overwritten when a new value
is entered.
Values modified via LAN are not automatically updated in the Base System
and thus are no longer correctly displayed in the Base System after the
modification. For this reason it is recommended to configure the default
gateway via the Base System. For the respective behaviour of the Base
System the appropriate manual should be considered.
If the IPv4 default gateway is not known, it must be requested by the network administrator. If
no standard gateway is available (special case), enter 0.0.0.0 in the input field or leave the
field blank.
6.3.2.1.6 Default Gateway IPv6
If the Ipv6 default gateway is not known, it must be requested by the network administrator. If
no standard gateway is available (special case), enter :: in the input field or leave the field
blank.

There are no MAC multicast addresses allowed!
6.3.2.2.3 DHCP
If DHCP is to be used, 0.0.0.0 should be entered as the IPv4 address via the
hopf
Base
System menu (likewise for gateway and network mask). This change can also be made via
the web interface by enabling the DHCP mode.
6.3.2.2.4 IPv4 Address
The IPv4 address is generally configured via the
hopf
Base System menu. However it can
also be changed via the web interface.
In Base System 7001 / 68xx, the changed LAN configuration is only stored in
the Board’s flash memory and is ALWAYS overwritten when a new value is

Values modified via LAN are not automatically updated in the Base System
and thus are no longer correctly displayed after the modification. For this
reason it is recommended to configure the IP address via the Base System.
For the respective behaviour of the Base System the appropriate manual
should be considered.
Contact your network administrator for details of the IPv4 address if not known.

also be changed via the web interface.
In the Base System 7001 / 68xx, the changed LAN configuration is only
stored in the Board’s flash memory and is ALWAYS overwritten when a new
value is entered.
Values modified via LAN are not automatically updated in the Base System
and thus are no longer correctly displayed after the modification. For this
reason it is recommended to configure the network mask via the Base
System. For the respective behaviour of the Base System the appropriate

6.3.2.2.6 Operation Mode
The network device usually adjusts the data stream and duplex mode to the device to which it
is connected (e.g. HUB, SWITCH) automatically. If the network device requires a certain speed
or duplex mode, this can be configured via the web interface. The value should only be
changed in special cases. The automatic setting is normally used.
In individual cases an enabled "Auto negotiate" might lead to problems
between the network components and the adjustment process fails.
In such cases it is recommended to set the network speed of the Board
7273(RC) and the connected network components manually to the same
value.
6.3.2.2.7 Maximum Transmission Unit (MTU)
The Maximum Transmission Unit describes the maximum size of a data packet of a protocol
of the network layer (layer 3 of OSI model), measured in octets which can be transferred into
the frame of a net of the security layer (layer 2 of OSI model) without fragmentation.
Board 7273(RC) is going to be delivered with default setting 1356.

6.3.2.2.8 IPv6
The Board 7273(RC) can also be operated in an IPv6 network.
To enable IPv6, Use IPv6 Settings must be set to enable.
IPv6 addresses are 128 bits long and they are recorded in eight 4-character hexadecimal
blocks. For example: 2001:0db8:0000:08d3:1319:8a2e:0370:7344
Leading zeroes in a 4-character hexadecimal block can be omitted. For the above example,
this results in the notation: 2001:db8:0:8d3:1319:8a2e:370:7344
In addition, once per IPv6 address a consecutive sequence of blocks containing all zeros may
be omitted. But this must be recorded with two consecutive colons. For the above example,
this gives the notation: 2001:db8::8d3:1319:8a2e:370:7344
Another example: 2001:0:0:0:1319:8a2e:0:7344 may be represented
as 2001::1319:8a2e:0:7344
or 2001:0:0:0:1319:8a2e::7344

6.3.2.2.12 VLAN (Activation Key necessary)
A VLAN (Virtual Local Area Network) is a logical sub-network within a network switch or a
whole physical network. VLANs are used to separate the logical network infrastructure from
the physical wiring, thus to virtualize the Local Area Network. The technology of VLAN is
standardized by IEEE Standard 802.1q. Network applications like Board 7273(RC),
implementing the standard IEEE 802.1q, are able to allocate individual network interfaces to
specific VLANs. To transfer data packets of several VLANs via a single network interface the
data packets are marked with a related VLAN ID. This method is called VLAN-Tagging. The
network application at the other end of the line (e.g. network switch, router etc.) can allocate
the data packet to the correct VLAN by checking the marking / tag.
WebGUI with activated VLAN
To be able to configure VLANs the activation status must be set to "enabled" first. Afterwards
up to 32 different VLANs per network interface can be configured by clicking the button "Add".
An explicit VLAN ID must be configured for each VLAN interface.
The boxes "Label" and "Remark" can be filled out with a designation or a comment to easily
keep the configured VLANs apart.
Determination of the IP-address for the configured VLAN interface can either be done
automatically via DHCP or by filling out the boxes "IP-Address" and "Network Mask".
To ensure the correct function the network appliance must be connected
with Board 7273(RC) via the network interface. Furthermore it must be
ensured that the network appliance is accurately configured with the same
VLANs.
VLAN ID one (1) and two (2) are reserved and are therefore not permitted!

In order to activate this function, Use Route File must be set to enabled on the Routing Page.
The routing file also makes it possible to configure IPv6 routes.
Via the selection window under Update file and the button Upload now a new routing file can

is used.
If a routing file has already been uploaded, the uploaded routing file can be downloaded under
Download Routing File.
Routing File Syntax
Each line of the routing file must be either a valid routing line or a comment line. A comment
line starts with a hash sign (#) and can contain any text behind it.
A routing line has the format [destination address] [tab] [length of the destination mask in bits]
[tab] [gateway address for the specified destination].
If the host 192.168.20.11 is to be reached using the gateway 192.168.0.2, then the routing file
must look like this:
192.168.20.11 32 192.168.0.2
Example of a Routing File:
# Host 192.168.20.11 via Gateway 192.168.0.2
192.168.20.11 32 192.168.0.2

Depending on the
hopf
Base System it may take several hours under unfavorable conditions
until long-term accuracy is obtained. During this time the NTP algorithm adjusts the internal
accuracy parameters.
NTP time protocol must be enabled in order to use NTP
(see Chapter 6.3.2.6 Time)
After all changes (according to NTP) have been done a restart of the NTP
service on the board is necessary (see Chapter 6.3.3.6 Restart NTP).
Via the NTP protocol SNTP Clients can also be synchronized. In contrast
to NTP in SNTP Clients delay times are not evaluated on the network. For
this reason the accuracy reached in SNTP Clients is lower than in NTP
Clients.
6.3.3.1 System Info
In the window "System Info" the current NTP values of the NTP service running on the
embedded Linux of the Board 7273(RC) are indicated. In addition to the NTP calculated values
for root delay, root dispersion, jitter, and stability the stratum value of the Board 7273(RC), the
status to the leap second, and the current system peer are also found here.
The NTP version used correctly adjusts the leap second.
The Board 7273(RC) works as NTP Server with stratum 1 and belongs to the best available
class of NTP server, as it has a reference clock with direct access.

6.3.3.4.3 Crystal Operation
Crystal Operation / Switch to specific stratum
If the
hopf
Base System runs in crystal operation (status “crystal“) the NTP service of the
Board 7273(RC) usually behaves in the way that the receipt of time information is stopped
from the Sync Source and the stratum value reset to 16 (defined as invalid in NTP).
NTP Clients does not accept time information from a NTP time server with
stratum 16 (invalid). Briefly, as long as the Board 7273(RC) indicates the
stratum value 16, NTP Clients are not synchronized.
This behaviour of NTP during crystal operation of the
hopf
Base System can be changed.
Therefore the function "Switch to specific stratum" should be enabled by setting the value to
"enabled" and the so-called downgrading stratum (= stratum value of the Board 7273(RC)
during crystal operation of the Base System).
For the sychronization of NTP Clients during crystal operation of the Base System or for testing
the system without connected synchronization source, in the setting "enabled" any stratum
value between 1 and 15 can be set.
Crystal Operation / Stratum in crystal operation
The value defined here (range 1-15) designates the transmitted fallback NTP stratum level of
the Board in "Quartz" synchronisation status. Stratum 1 should be configured if downgrading
is not desired in status "Quartz" of the base system.
Changes in data do not take effect immediately after clicking on the Apply
symbol. The NTP service MUST also be restarted (see Chapter 6.3.3.6
Restart NTP.
Using the option "Switch to specific stratum" the NTP Clients are
synchronized with time information indicated in the general menu of the
WebGUI of the Sync Source during crystal operating of the Base System.
Whether this time information (e.g. through drift) is imprecise or the time is
manually set (wrong) cannot be detected by the NTP Client!
In case the value 1 is used for "Stratum in crystal operation", the NTP
Client cannot not verify whether the Base System is synchronised or runs
in crystal operation. Should a differentiation be wished between
synchronized and crystal operation the downgrading stratum needs to be
set to a value between 2 and 15.
The value is only adjustable if the "Switch to specific stratum" function is enabled.

6.3.3.4.4 Broadcast / Broadcast Address
This section is used to configure the Board as a broadcast or multicast server.
The broadcast mode in NTPv3 and NTPv4 is limited to clients on the same sub-network and
Ethernet which support broadcast technology.
This technology does not generally extend beyond the first hop (network node - such as router
or gateway).
The broadcast mode is provided for configurations which are designed to facilitate one or more
servers and as many clients as possible in a sub-network. The server continuously generates
broadcast messages at defined intervals, corresponding to 16 seconds (minpoll 4) on the LAN
Board. Care should be taken to ensure that the correct broadcast address is used for the subnetwork, usually xxx.xxx.xxx.255 (e.g. 192.168.1.255). If the broadcast address is not known,
this can be requested from the network administrator.
This section can also be used to configure the LAN Board as a multicast server. The
configuration of a multicast server is similar to that of a broadcast server. However, a multicast
group address (class D) is used instead of the broadcast address.
An explanation of multicast technology goes beyond the scope of this document.
In principle, a host or router sends a message to an Ipv4 multicast group address and expects
all hosts and routers to receive this message. In doing so, there is no limit to the number of
senders and receivers and a sender may also be a receiver and vice-versa. The IANA has
assigned the multicast group address IPv4 224.0.1.1 to the NTP, however this should only be
used if the multicast range can be safely limited in order to protect neighbouring networks. As
a basic principle, administratively manageable IPv4 group addresses should be used as
described in RFC-2365 or GLOP group addresses as described in RFC-2770.
6.3.3.4.5 Broadcast / Authentication / Key ID
Broadcast packets can be protected by authentication for security reasons.
If a security method is selected here this must be configured additionally in the security
settings of the NTP tab. A key must be defined if the “Symmetric Key” is selected.
6.3.3.4.6 Additional NTP SERVERS
The addition of further NTP servers provides the opportunity to implement a security system
for the time service. However, this has an effect on the accuracy and stability of the Board.
Detailed information on this subject can be found in the NTP documentation
(http://www.ntp.org/).

6.3.3.5 Extended NTP Configuration
NTP is a protocol for synchronising clocks of computer systems over packet-switched data
networks. For special applications the NTP time base of board 7273(RC) can be configured to
local and standard time via the base system.
For activation of this special NTP output, the customer's approval shown in the WebGUI
needed to be declared by checking the field "I agree".
6.3.3.5.1 Suppression of unspecified NTP outputs (Block Output when Stratum Unspecified)
Unspecified NTP outputs that e.g. are generated by NTP at re-start, are suppressed when this
function is activated.
6.3.3.5.2 NTP Timebase
For custom applications this function enables adjustment of the time base of the NTP output.
Entering this function the transmitted time protocol of the board 7273(RC)
is not conform to the NTP standard anymore.
According to the NTP standard NTP uses only the UTC time base. The NTP
time protocol does not allow any leaps in time.
This function is only allowed for the Output of NTP
In case of activated function the output of the board 7273(RC) for SINEC H1
TIME DATAGRAM / TIME / DAYTIME is released with a wrong time basis.
Therefore this datagram should be deactivated for security reasons.

correspond with UTC plus the time difference, adjusted in the base system without
considering the daylight saving time changeover.
NTP with the Time Base Local Time
Output of the NTP time protocol with the local time base the released time information
correspond with UTC plus the time difference and the additional offset for the possible summer
time, adjusted in the base system.
NTP does not allow any leaps in time. Using the NTP time protocol with the local time base
the internal NTP process of a board is restarted based on a summer-/winter time adjustment.
Using the NTP time protocol with the local time base the summer-/winter
time adjustment is released one to two minutes belated.
Afterwards the local time is correctly available in the NTP time protocol.
Therefore, within this transition period a requested NTP time protocol is
replied by the former time base.
Changing the time base for the output of the protocol for NTP is only
designed for customized applications and does not correspond with the
standard of NTP. The synchronisation of a standard NTP-Client with a time
basis deviating from UTC results in a wrong time information in the standard
NTP-Client and might cause time leaps!

6.3.3.6 Restart NTP
The following screen appears after clicking on the Restart NTP option:
Restarting NTP Services is the only possibility of making NTP changes effective without having
to restart the entire Board 7273(RC). As can be seen from the warning message, the currently
reachable stability and accuracy are lost due to this restart.
After a restart of the NTP service it takes up to 10 minutes until the NTP
service on the board 7273(RC) is completely adjusted and synchronised
with the system time of the base system again.
6.3.3.7 Access Restrictions / Configuring the NTP Service Restrictions
One of the extended configuration options for NTP is "Access Restrictions".
Restrictions are used in order to control access to the Board’s NTP service and these are
regrettably the most misunderstood options of the NTP configuration.
If you are not familiar with these options, a detailed explanation can be found at
http://www.ntp.org/.

IP addresses should be used when configuring the restrictions – no
Hostnames!
The following steps show how restrictions can be configured – should these not be required it
is sufficient to retain the standard settings.
The standard restrictions tell the NTP service how to handle packets from hosts (including
remote time servers) and sub-networks which otherwise have no special restrictions.
The NTP configuration can simplify the selection of the correct standard restrictions whilst
making the required security available.
Before beginning the configuration the points 6.3.3.7.1 to 6.3.3.7.4 must be checked by the
user:
6.3.3.7.1 NAT or Firewall
Are incoming connections to the NTP Service blocked by NAT or a Stateful
Inspection Firewall?
No
Proceed to Chapter 6.3.3.7.2 Blocking Unauthorised Access
Yes
No restrictions are required in this case.

6.3.3.7.5 Addition of Exceptions to Standard Restrictions
After the standard restrictions have been set, certain exceptions may be necessary for special
hosts/sub-networks in order to allow remote time servers and client hosts/sub-networks to
contact the NTP service.
These standard restrictions are to be added in the form of restriction lines.
Unrestricted access of Board 7273(RC) to its own NTP service is always
allowed, irrespective of whether standard restrictions are ignored or not.
This is necessary in order to be able to display NTP data on the web
interface.

6.3.3.7.6 Access Control Options
The official documentation concerning the current implementation of the restriction instructions
can be found on the “Access Control Options” page at http://www.ntp.org/.
Numerous access control options are used. The most important of these are described in detail
here.
nomodify – "Do not allow this host/sub-network to modify the ntpd settings unless it has the
correct key.“
Default Settings:
Always active. Can't be modified by the user.
As standard, NTP requires authentication with a symmetric key in order to carry out
modifications with ntpdc. If a symmetric key is not configured for the NTP service, or if this is
kept in a safe place, it is not necessary to use the nomodify option unless the authentication
procedure appears to be unsafe.
noserver – "Do not transmit time to this host/sub-network."
This option is used if a host/sub-network is only allowed access to the NTP service in order to
monitor or remotely configure the service.
notrust – "Ignore all NTP packets which are not encrypted.“
This option tells the NTP service that all NTP packets which are not encrypted should be
ignored (it should be noted that this is a change from ntp-4.1.x). The notrust option MUST NOT
be used unless NTP Crypto (e.g. symmetric key or Autokey) has been correctly configured on
both sides of the NTP connection (e.g. NTP service and remote time server, NTP service and
client).
noquery – "Do not allow this host/sub-network to request the NTP service status."
The ntpd status request function, provided by ntpd/ntpdc, declassifies certain information over
the running ntpd Base System (e.g. operating system version, ntpd version), which under
certain circumstances ought not to be made known to others. It must be decided whether it is
more important to hide this information or to give clients the possibility of seeing
synchronisation information over ntpd.
ignore – "In this case ALL packets are refused, including ntpq and ntpdc requests".
kod – "A kiss-o'-death (KoD) packet is transmitted if this option is enabled in the case of an
access error."
KoD packets are limited. They cannot be transmitted more frequently than once per second.
Any KoD packet which occurs within one second from the last packet is removed.
notrap – "Denies support for the mode 6 control message trap service in order to synchronise
hosts."
The trap service is a sub-system of the ntpq control message protocols. This service logs
remote events in programmes.
version – "Denies packets which do not correspond to the current NTP version."
Changes in data do not take effect immediately after clicking on the
“Apply” symbol. The NTP service MUST also be restarted (see Chapter
6.3.3.6 Restart NTP ).

6.3.3.8 Symmetric Key and Autokey
6.3.3.8.1 Why Authentication?
Most NTP users do not require authentication as the protocol contains several filters (for bad
time).
Despite this, however, the use of authentication is common.
There are certain reasons for this:
• Time should only be used from safe sources
• An attacker broadcasts false time signals
• An attacker poses as another time server

6.3.3.8.2 How is Authentication used in the NTP Service?
Client and server can execute an authentication whereby a code word is used on the client
side and a restriction on the server side.
NTP uses keys to implement the authentication. These keys are used when data is exchanged
between two machines.
In principle both sides must know this key. The key can generally be found in the
“*.*/etc/ntp.keys“ directory. It is unencrypted and hidden from public view. This means that the
key has to be distributed on a safe route to all communication partners. The key can be
downloaded for distribution under “Downloads” on the DEVICE tab. It is necessary to be
logged in as “Master” in order to access this.
The keyword key of a client’s ntp.conf determines the key that is used to communicate with
the designated server (e.g. the NTP LAN board). The key must be reliable if time is to be
synchronised. Authentication causes a delay. This delay is automatically taken into account
and adjusted in the current versions.
6.3.3.8.3 How is a key created?
A key is a sequence of up to 31 ASCII characters. Some characters with special significance
cannot be used (alphanumeric characters and the following symbols can be used:
. , ! " $ % & / { } [ ] ( ) = ? \ + - @ * ~ # ' < > | ; : _
A new line can be inserted by pressing the ADD key. The key which is stored in the key file
is entered on this line. The key ID is used to identify the key and is in the range from 1 – 65534.
This means that 65534 different keys can be defined.
Duplicate key ID’s are not allowed. Having now explained the principles of keys, it should be
possible to use a key in practically the same way as a password.
The value of the request key field is used as the password for the ntpdc tool while the value of
the control key field is used as the password for the ntpq tool.
More information is available at http://www.ntp.org/.
6.3.3.8.4 How does authentication work?
Basic authentication is a digital signature and not data encryption (if there is any difference
between the two). The data packet and the key are used to create a non-reversible number
which is attached to the packet.
The receiver (which has the same key) carries out the same calculation and compares the
results. Authentication has been successful if the results concur.

6.3.3.9 Autokey / Public Key Cryptography
NTPv4 offers a new Autokey scheme based on public key cryptography.
As a basic principle, public key cryptography is safer than symmetric key cryptography,
as protection is based on a private value which is generated by each host and is never visible.
In order to enable Autokey v2 authentication, the “Autokey Enabled” option must be set to
"enabled" and a password specified (may not be blank).
A new server key and certificate can be generated by pressing the "Generate now" button.
Generate now
This should be carried out regularly as these keys are only valid for one
year.
If the NTS board is to form part of an NTP trust group, a group key can be defined and
uploaded with the "Upload now" button.
Detailed information about the NTP Autokey scheme can be found in the NTP documentation
(http://www.ntp.org/).
Changes in data do not take effect immediately after clicking on the “Apply”
symbol. The NTP service MUST also be restarted (see Chapter 6.3.3.6
Restart NTP).

6.3.4 ALARM Tab
All the links within the tabs on the left hand side lead to corresponding detailed setting options.
6.3.4.1 Syslog Configuration
It is necessary to enter the name or IPv4 or IPv6 address of a Syslog server in order to store
every configured alarm situation which occurs on the Board in a Linux/Unix Syslog. If
everything is configured correctly and enabled (dependent on the Syslog level), every
message is transmitted to the Syslog server and stored in the Syslog file there.
Syslog uses Port 514.
Co-logging on the Board itself is not possible as the internal memory is not of sufficient size.
It should be noted that the standard Linux/Unix Syslog mechanism is used for this functionality.
This is not the same as the Windows System Event mechanism!
The alarm level designates the priority level of the messages to be transmitted and the level
from which transmission is to take place (see Chapter 6.3.4.4 Alarm ).

6.3.4.2 E-mail Configuration
E-mail notification is one of the important features of this device which offer technical
personnel the opportunity to monitor and/or control the IT environment.
It is possible to configure various, independent E-mail addresses which each have different
alarm levels.
Dependent on the configured level, an E-mail is sent after an error has occurred on the
respective receiver.
A valid E-mail server (SMTP server) must be entered for the purpose of correct configuration.
Some E-mail servers only accept messages if the sender address entered is valid (spam
protection). This can be inserted in the “Sender Address” field.

6.3.5.5 Image Update & H8 Firmware Update
Patches and error recovery are provided for the individual Boards by means of updates.
Both the embedded image and the H8 firmware can only be downloaded to the Board via the
web interface (login as “Master” user required). See also Chapter 2.4 Firmware Update.
The following points should be noted regarding updates:
• Only experienced users or trained technical personnel should carry
out an update after checking all necessary preconditions.
• Important: Faulty updates or update attempts may under certain
circumstances require the Board to be returned to the factory for
rectification at the owner’s expense.
• Check that the update on hand is suitable for your Board. If in doubt
please consult the support of the
hopf
company.
• In order to guarantee a correct update, the "New version of saved
site" function must be set to "On each access to the site" in the
Internet browser used.
• During the update procedure, the device must not be switched off
and settings must not be saved to the flash memory!
• Updates are always executed as software set. I.e. H8 firmware
update + image update. Unless specifically defined otherwise in the
SET, it is absolutely essential to complete the H8 firmware update
first, followed by the image update.
• For the Update please pay attention to the points in Chapter 2.4
Firmware Update.
In order to carry out an update, enter the name and the folder in which the update / firmware
image is located in the text field or open the file selection dialogue by pressing the "Browse"
button.
Correct firmware and image designations are (e.g.):
8029_7273_128_v0201.mot
for the H8 firmware (update takes approx. 1-1.5 minutes)
upgrade_8029-SERI_gen_rel_v0700.img
or upgrade_8029-NAND_gen_rel_v0700.img

6.3.5.8 Option FG7273/PPM: Minute Pulse Length (PPM)
With this option FG7273/PPM a high active isolated minute pulse (high active) of +12V DC is
distributed on the 3-pole screw terminal. Further technical data can be found in Chapter 8
Technical Data.
The output is an "open collector" with a current limiter. For further information see Chapter
1.3.1.7 Option: Active 12V DC PPM (Minute Pulse).
This minute pulse is fully compatible to the minute pulse of the
hopf
board
7270/7271 (the electrical properties as well as the adjustable parameters).
The menu item Minute Pulse (PPM) is only indicated in WebGUI if this
function is also available for the board.
Both boards 7273 and 7273RC are available with the option FG7273/PPM.
A subsequent upgrading of this option is not possible by the customer.
The length of the pulse can be adjusted in 4 steps.

7 SSH and Telnet Basic Configuration
Only basic configuration is possible via SSH or Telnet. The complete
configuration of Board 7273(RC) takes place exclusively via the WebGUI.
It is just as easy to use SSH (Port 22) or Telnet (Port 23) as the WebGUI. Both protocols use
the same user interface and menu structure.
The user names and passwords are the same as on the WebGUI and are kept in alignment
(see Chapter 6.3.5.11 Passwords (Master/Device)).
SSH does not allow blank passwords for safety reasons.
The corresponding service is to be enabled for the use of Telnet or SSH
(see Chapter 6.3.2.5 Management-Protocols – HTTP, SNMP etc.)
Navigation through the menu takes place by entering the respective number associated with
the menu option (as can be seen in the above image).

9 Factory Defaults of Board 7273(RC)
The default delivery status of the Board 7273(RC) meets the factory default values when using
GPS synchronization sources. In case of DCF77 synchronization (different product variant)
the function "NTP / General / Sync Source" is factrory-set to "DCF77" on delivery.
Using the board in DCF77 systems (different product variant) the setting
for NTP / General / Sync Source" needs to be re-configured to "DCF77"
after a factory default.
