5. Module replacement instructions

Before handling the boards there are a few, but important instructions that must be observed:

Throughout the whole process of manufacturing and testing, the products have been kept in static

shielding bags, and all personnel handling the products have been protected against static electricity

and the subsequent ESD (electrostatic discharge).

Consequently, we ask you to observe certain rules when handling our products - otherwise our efforts

may be wasted:

Be sure to carry a connection to earth when handling our PCBs. If the correct equipment (bracelet, IC

tongs) is not available, you must improvise. You may e.g. place an open wire under your watch and

connect this to earth via a heavy resistor (1 MΩ). As to earth connection, it should be possible to use

the rack frame or the cabinet. Note that the limit for registration of static electricity for a human being is

considerably higher than the limit above which electronics and electronic components are damaged.



BE AWARE OF STATIC ELECTRICITY WHEN HANDLING!

Each module is fastened to the rack with M2.5 Pozidriv® collar screws. These should be loosened

before the extraction handles are used to lift the module free of the rack. When remounting the

modules the M2.5 Pozidriv® collar screws must be tightened with 0.7...0.8 Nm to assure the products

robustness towards vibration as well as shocks.

5.3. Adding/replacing mSATA cards on the PCM5·2 module

The PCM5·2 module has a mSATA card slot placed inaccessible from the outside. This placement is

to prevent disruption of operation of the card during production. Adding/replacement of the mSATA

module is done by removing the PCM5·2 module from the racks as described above.

5.4. Replacing the RTC Battery on the PCM5·2 module

The PCM5·2 has a lithium battery for maintaining the real-time clock, when not power is applied. The

life time of the battery is 10 years, thus the battery needs to be replaced on scheduled basis.
