3 LANTIME IMS M4000 System Description
3 LANTIME IMS M4000 System Description
3.1 Device Design, Functions and Area of Application
The IMS-LANTIME-System is a set of equipment composed of a reference module, a single-board computer
module (LAN-CPU) with integrated network card, and a power supply unit, all installed in a modular chassis
and ready to operate. The input/output signals of the IMS systems are provided on the connection side via I/O
modules.
The implemented NTPD distributes the reference time from the reference module cyclic in the network. Infor-
mation on the NTPD is monitored on the LC-Display (if available) or can be queried via the network.
The installation of an IMS LANTIME is very easy for the system/network administrator. The network ad-
dress, the netmask and the default gateway have to be configured from the front panel of LANTIME. The
network address or the equivalent name of LANTIME has to be shown to all NTP clients in the TCP/IP network.
As well as NTP the Linux system also supports a number of further network protocols: HTTP(S), FTP, SSH
and Telnet. Because of this remote configuration or status requests can come from any WEB browser. This
access via the network can be deactivated. Changes in the receiver status, errors or other important events are
logged either on the local Linux system or on an external SYSLOG-Server. In addition messages can be sent to
a data center via SNMP traps or automatically generated e-mails where they can be recorded. Furthermore all
alarm messages can be displayed by the large display VP100/20/NET that is accessed via network connection.
In order to avoid a service interruption several LANTIME NTP servers can be installed in the same network to
obtain redundancy.

3.3.2 Environmental Requirements
Protection Rating: IP20
Ambient Temperature: 0 ... 50 ◦C
Storage Temperature: -20 ... 70 ◦C
Humidity: max. 85% (non-condensing) @ 30 ◦C
Please Note:
To prevent overheating damage during operation, some
IMS systems are equipped with an active cooling mod-
ule (ACM). The generated air flow is led through the
system as shown in the figure on the right (see also
chapter "ACM - Active Cooling Module" or "RCU - Rack
Cooling Module").
Active cooling with ACM modules.
Active cooling modules are available for the M4000,
M3000 and M1000(S) IMS systems. For the M4000
and M3000, the use of an ACM is optional. M1000
and M2000 systems are always equipped with an ACM.
Passive cooling.
Due to the small installation depth, it is not possible to
integrate an ACM module in an M3000S system. For
this reason, we have developed a 1U passive cooling
enclosure that can be installed under the IMS system
in the server rack. The RCU module (Rack Cooling
Unit) provides an optimal airflow for the dissipation of
the warm air.

considerable risks for the user and result in a loss of warranty as well as an exclusion
of liability.
- Danger due to moving parts - keep away from moving parts.
- Device parts can become very hot during operation. Do not touch these surfaces!
If necessary, switch off the unit before installing or removing any equipment,
and allow it to cool down.
4.7 Handling Batteries
CAUTION!
The lithium battery on the receiver modules has a service life of at least 10 years.
If an exchange is necessary, the following notes must be observed:
The device is equipped with a lithium battery. The battery must not be short-circuited
or recharged. Replacement of the lithium battery may only be carried out by the manufacturer
or authorized personnel.
Risk of explosion if the battery is not replaced correctly. Replace only with the same or
equivalent type recommended by the manufacturer.
When disposing used batteries, observe the local regulations for the disposal of
hazardous waste.

4 Important Safety Information
4.8 Cleaning and Care
ATTENTION!
Do not wet clean the appliance! Penetrating water can cause considerable dangers to
the user (e.g., electric shock).
Liquid can destroy the electronics of the device! Liquid penetrates into the housing
of the device and can cause a short circuit of the electronics.
Only clean with a soft, dry cloth. Never use solvents or cleaners.
4.9 Prevention of ESD Damage
ATTENTION!
The designation ESD (Electrostatic Sensitive Devices) refers to measures which are used
to protect electrostatically endangered components from electrostatic discharge and thus
to prevent destruction. Systems and assemblies with electrostatically endangered components
usually have the following characteristics:
Indicator for assemblies with electrostatic endangered components
The following measures protect electrostatically endangered components from destruction:
Prepare removal and installation of assemblies
Unload yourself (for example, by touching a grounded object) before touching assemblies.
Ensure that you wear a grounding strap on the wrist when working with such assemblies, which
you attach to an unpainted, non-conductive metal part of the system.
Use only tools and devices that are free from static electricity.
Transporting Assemblies
Assemblies may only be touched at the edge. Do not touch any pins or conductors on assemblies.
Installing and Removing Assemblies
Do not touch persons who are not grounded while removing or installing components. This could
result in a loss of grounding protection from your electrostatic discharge.
Storing Assemblies
Always keep assemblies in ESD protective covers. These protective covers must be undamaged.
ESD protective covers, which are extremely wrinkled or even have holes, no longer protect against
electrostatic discharge.
ESD protective covers must not be low-resistance and metallically conductive if a lithium battery
is installed on the assembly.
