2 Introduction
This Setup Guide is a systematically structured guideline to assist you with the set-up of your Meinberg product.
Functionality of IMS-RSC180
The RSC Redundant Switch Control module controls the switchover mechanism between two reference clocks
in redundant systems with two Meinberg clock modules. The RSC is used to switch between the connected
clocks and to select the corresponding pulse, frequency outputs, and serial interfaces. The RSC module can
be configured with various operating modes that dictate how the module switches between clocks. The status
LEDs indicate which clock is currently selected as the Master Clock, as well as the current operating state of
the switch control module.
Please refer to the LANTIME Firmware Manual for a more detailed description of all of the status moni-
toring configuration options and features available for your Meinberg product.

3 Important Safety Information
3 Important Safety Information
Please ensure that IMS modules designed for "hot-plugging" (modules that are removable and insertable while
a system is in operation) are always handled with the utmost care.
Before performing any maintenance work on the system:
•We recommend making a backup of any stored configurations (e.g. using a USB flash drive or from the
Web UI)
•Take note of the chapter "Prevention of ESD Damage".
•Take note of the chapter "Power Supply".
3.1 Additional Safety Information
This manual contains important safety information regarding the installation and use of the device. Please read
it through fully before setting up the device for use.
This device may only be used for the purpose described in this manual. In particular, the specified operat-
ing limits of the device must be heeded. The person setting up the device is responsible for safety matters in
relation to any larger system in which the device is installed!
Failure to observe these instructions may have an adverse impact on device safety!
Please keep this manual in a safe and accessible place.
Target Readership

3.2 Prevention of ESD Damage
ATTENTION!
An ESDS device (electrostatic discharge-sensitive device) is any device at risk of damage or
malfunction due to electrostatic discharges (ESD) and thus requires special measures to prevent
such damage or malfunction. Systems and modules with ESDS devices usually bear the following
symbol:
Symbol Indicating Devices with ESDS Components
The following measures will help to protect ESDS components from damage and malfunction.
When preparing to dismantle or install devices:
Ground your body (for example, by touching a grounded object) before touching sensitive devices.
Ensure that you wear a grounding strap on your wrist when handling such devices. These straps must
in turn be attached to an uncoated, non-conductive metal part of the system.
Use only tools and devices that are free of static electricity.
When transporting devices:
Devices must only be touched or held by the edges. Never touch any pins or conductors on the device.
When dismantling or installing devices:
Avoid coming into contact with persons who are not grounded. Such contact may compromise your
connection with the earth conductor and thus also compromise the device’s protection from any
static charges you may be carrying.
When storing devices:
Always store devices in ESD-proof ("antistatic") bags. These bags must not be damaged in any way.
ESD-proof bags that are crumpled or have holes cannot provide effective protection against
electrostatic discharges.
ESD-proof bags must have a sufficient electrical resistance and must not be made of conductive
metals if the device has a lithium battery fitted on it.

3 Important Safety Information
3.3 Power Supply
WARNING!
The IMS system in which the module is used is operated at a dangerous voltage. Please refer to your IMS
Manual for more information about safety.
When removing a hot-pluggable power supply unit, always disconnect its power cable before removing it from
the IMS system.
Never open a power supply unit—there may still be hazardous residual voltages present even after disconnec-
tion from the mains supply. In the event that a power supply unit is no longer working (e.g. defective), please
return it to Meinberg for repair.
Failure to observe these safety instructions may result in serious injury and/or property damage. The IMS
system must only be installed, set up, and operated by qualified personnel.
3.4 Cabling
WARNING!
Danger of death from electric shock! Never work on the system while the power is live! Always disconnect the
cables from the devices at both ends before working on the plugs and terminals of connected cables!

1. LED Indicator
Clock 1 / Clock 2 (SDI 1 / SDI 2)
These LEDs show which of the two reference clocks is currently the "Master Clock".
Remote
This indicates whether the module is currently being managed remotely over an Ethernet connection. In remote
mode, the Master Clock can be selected using an SNMP command. The most recent state set while in remote
mode will be retained after control is handed back to the local automatic controller, unless this state is incon-
sistent with the control logic (e.g., if the clock has been configured to run solely from the oscillator).
Init
This LED lights up blue while the RSC switch control module is being initialized.

2. Auto/Manual Switch
This switch selects between Automatic and Manual mode. Manual mode overrides the module’s internal selec-
tion logic and the reference clock used for signal generation can only be selected manually using the Clock 1
/ Clock 2 switch. In Manual mode, outputs are always enabled, regardless of the synchronization state of the
clocks.
"Auto" Switch Position
The reference clock is selected by the RSC’s internal control logic. The Master Clock is selected based on the
TIME_SYNC signals generated by the receivers, which indicate the synchronization status of the clocks.
To prevent switchovers from being unnecessarily performed (for example, if one clock regularly falls back to
a free-running oscillator while the other is synchronized), the Master and Backup Clock will be swapped upon
each switchover. This Master/Backup relationship will only be swapped back if the new Master Clock (formerly
the Backup Clock) loses synchronization while the Backup Clock (formerly the Master Clock) is synchronized.
If both clocks are running off their respective oscillators, no switchover will be performed; the current state will
be retained and the outputs are disabled if so configured (using the menu & controls on the device’s display).
Important: To ensure that the automatic switchover mechanism is effective, the remote management functionality
must be disabled via the display panel menu: Ref. Time →Switch Unit →SCU Cntl →MANUAL: disable. If
remote management is left active, the system will use the clock selected by the manual control mechanism and
the unit will not switch over to the current Master Clock.
Manual Mode (Display Panel Menu)
In Manual mode, the reference clock is selected from the display panel menu. In this case, errors will not cause
the reference clock to be switched over, and pulse & frequency outputs as well as the serial interfaces will
remain enabled.
Menu: Switch Unit →SCU Cntl →MANUAL : enable
Note:
A LANTIME Display Unit (LDU) can optionally be used for systems without a display panel (M1000S and
M3000S).

3. Clock 1 / Clock 2 Switch (SDI 1 / SDI 2)
This switch is used to manually select the receiver or input reference in "Manual" mode. No automatic switchover
is performed in the event of the selected input reference losing its signal.
4. ACO Button (Access Control Override)
The button labeled ACO can be used if the access password has been forgotten. However, it will only work if
there is no connection with the "Meinberg Device Manager" software. If it is held down for a short time (for
around four seconds), the set password will be reset for 30 seconds to a blank field (i.e., you can simply press
RETURN when prompted for the password). After these 30 seconds, the system will then restore the password
to its previous value. This applies to connections made via both Telnet and mbgdevman. If a connection to
mbgdevman is established during the 30 seconds, the "empty" password will remain valid for the duration of this
connection (even if this connection is upheld for longer than 30 seconds). In this case, the old password will
only restored when the connection is terminated.
5. Network Interface (MDU only)
RSC switching modules used in an MDU system feature a network interface which can be used to configure the
system and components of the system; for this purpose you will require the "Meinberg Device Manager" software.

6 System Installation
6.1 Important Information Regarding Hot-Pluggable IMS Modules
The following information should be strictly observed when replacing IMS modules during operation. Not all
IMS modules are fully hot-pluggable. For example, it is naturally not possible to replace a power supply unit in
a system without PSU redundancy without first having installed a second power supply unit while the system
is in operation.
The following rules apply for the individual IMS slots:
PWR Slot: "Hot-Swappable" If you operate your system with only one power supply unit,
a second power supply unit must be installed before removing
or replacing it in order to keep your system on.
I/O, ESI and
MRI Slots: "Hot-Pluggable".
CLK1/CLK2 "Hot-Pluggable" When a clock module is replaced or installed, it is important to rescan
Slots: the reference clocks ("Rescan Refclocks") in the "System" menu
of the Web Interface.
RSC/SPT Slots: "Hot-Pluggable" It will not be possible for your IMS system to switch between signal
generators while the RSC/SPT is not installed.
——————————————————————————————————————————————
CPU Slot: "Not Hot-Pluggable" Before the CPU is removed, the IMS system must be powered down.
Please note that after powering on and rebooting the LANTIME
Operating System, the configuration of some IMS modules may be reset
to factory defaults!
The NTP service and access to the web interface will be unavailable while the CPU
is not installed. Management and monitoring functions will also be disabled.

6 System Installation
6.2 Installation of Hot-Pluggable IMS Modules.
If the system is supplied with an antenna and antenna cable, it is advisable to first mount the antenna in
a suitable location (refer to the chapter "Mounting the Antenna" in your IMS system manual) and to lay the
antenna cable.
Please use a Torx screwdriver (T8 x 60) to remove and install IMS modules.
1. Follow the safety instructions at the beginning
of this manual!
2. Remove the two marked Torx screws from the
module holder plate or the cover plate of
the empty slot.
3. Please note when removing modules:
The module must be pulled carefully out of the
guide rail. Note that the module will be
securely seated in the connector block inside
the chassis—a certain amount of force must
be applied to release the module. Once the
module has been detached from the connector
block in the system backplane, the module can
be easily pulled out.
4. Please note when installing modules:
Ensure that the module is correctly inserted into the two guide rails of the system chassis. Failure
to do so may result in damage to the module and chassis. Ensure that the module is securely seated
in the connector block inside the chassis before you fasten the two screws.
5. The installed module is now ready for use.
