3. E01 Disassembly and assembly
DANGER
Removing the cover of an E01 unit exposes dangerous voltages. Ensure that the unit is
switched off and the plug removed from the mains supply before removing the cover.
WARNING
A number of components within the units are STATIC SENSITIVE. It is possible that these
components may be damaged if subjected to a static discharge. Avoid contact with the
components of the PCBs except where necessary to perform the exchange or faulty
components. When exchanging components, take appropriate anti-static precautions.
3.1 Disassembly procedure
(1) Power down the FileStore unit for disassembly.
(2)
Disconnect the unit from the mains.
(3)
Unclip the front and rear mouldings.
(4)
Unclip the side mouldings.
(5)
Remove the four screws holding the top metal wrap to the unit and slide it off backwards.
If you want to access the circuit board or remove the drive(s) then remove the top shield from
the drive(s) and remove the mounting screws in the base plate. Disconnect the (data) ribbon
and power connectors. This allows the drive to be removed, up and backwards.
The floppy disc units are not a serviceable item, and in the event of failure should be replaced
by a new or reconditioned unit.
The floppy disc interface is contained on the E0l main processor board. If the interface is
suspected to be faulty, refer to Appendix A -
Test Equipment, which contains a suitable test of
the floppy disc interface.
3.2 Assembly procedure
To reassemble the unit, simply reverse the above procedure.
When reassembling the unit, ensure that full earth testing has been satisfactorily completed.
