Hardware Maintenance
The IMx-M hardware, for example the IMx-M rack, is virtually maintenance free.
However, we advise the customers to make an annual inspection of the equipment.
Maintenance of Sensors
Visual inspections for looseness or any physical damage on sensors, sensor cables and
connectors shall be conducted on regular basis, such as annually.
In addition, sensors shall be maintained according to the individual sensor
manufacturer's instruction.
Ventilation Fan
Ventilation fans in the system shall be cleaned regularly in order to maintain the full
ventilation capacity.
Hot-swap
For the service purpose, modules can be dismounted or mounted by trained personnel
or service personnel during the normal operation.
Note the following conditions for hot - swap:

All modules in front panel are hot-swappable.

Rack must be in disarmed mode.

A PRM must have DIP switches correctly set before insertion into
the rack.

Hot swapped modules must then be configured correctly (updated),
before the rack/slot is armed.
To hot-swap a CMM, perform the following steps:
1. Disarm the rack.
2. Remove the CMM and insert a new CMM according to the Changing PSU or CMM
instruction.
3. When all STATUS Ready LEDs indicate that all the modules in the rack are
configured and running (slow green flash), arm the rack.
To hot-swap a PRM, perform the following steps:
1. Disarm the rack.
2. First, remove the corresponding CMM (left side of the PRM) according to the
Changing PSU or CMM instruction steps 1 to 3.
3. Remove the protection module according to the Changing RLM or PRM instruction
steps 1 to 4.
4. Take the new protection module and match all DIP switches of the new module to
all DIP switches of the old module. For simplicity, we propose a systematic
