2 Safety Instructions for hot pluggable Modules
Check before every maintenance work on the system:
•If a data backup is required?
•Is a backup required, verify the data recovery which is done by this backup.
•Make sure to avoid any static discharge while working - use a grounding cable and/or antistatic gloves
during installation and removal of hot pluggable components.
•If you are replacing a hot pluggable power supply, unplug the power cable prior to removing the module
from the case.
•Never open a power supply. In power supplies dangerous voltages can still remain even after disconnection
from the power supply. Always send power supplies back to the manufacturer for maintenance.
Exchange of hot-swap components
•Ensure that components which will be replaced during operation, always be treated with the utmost care.
Avoid contact with live components.
•Electrostatic discharge can damage electronic components. For this reason, ensure protection against
electrostatic discharges by wearing anti-static shoes while working with the system.
•Take care when removing and installing the hot-plug modules. Always work with the utmost caution.
Touch the modules only at the edges.
•Place the module out of the box or after removal from the system with the component side to the top on
a grounded and static-free surface.
•Storage of an IMS module must be done in a dry place.
•Installation or removal from hot-swap components only by authorized personnel!

3 Replacement or Installation of a Hot-pluggable IMS Module
3 Replacement or Installation of a Hot-pluggable
IMS Module
Please use a Torx screwdriver (T8 x 60) for removal and installation.
1. Follow the safety instructions at the beginning
of this manual!
1. Remove the two marked Torx screws from the
module holder plate or the cover plate of
the empty slot.
2. (Only for an already built-in module)
Pull the module carefully out of the holding
rail. Note that the module is firmly anchored
in the connector block of the housing. You need
a certain amount of force to release the module
from this link. Once the connection to the
connector block of the system’s backplane is
loosened, the module can be easily pulled out.
3. When installing the new IMS module, please ensure that the board is correctly inserted into the
two guide rails of the system housing. Non-observance can cause damage to the module and the chassis.
Make sure that the module is securely locked into the connector block before you fasten the two screws.
4. Now you can put the installed module into operation.
