3. E40S/E60S Disassembly and assembly
DANGER
Removing the cover of an E40S or E60S 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 hard disc at all times without taking adequate precautions against static.
WARNING
When the hard disc drive is removed for service work, great care must be taken not to
drop, jar or shock the unit in any way. Under no circumstances should the drive itself
be opened to expose the head mechanism: this can only be done by the manufacturer in
a special ultra-clean room
3.1 Disassembly procedure
The numbered items mentioned in the following procedure refer to the E40S/E60S final
assembly drawing in Appendix C.
(1)
Power down the unit for disassembly.
(2) Disconnect the unit from the mains.
(3) Remove the unit from the stack.
(4) Remove the rear p1astic moulding (Item19) by levering the top up and back. The
p1astic mouldings are fixed to the FileStore box by locating lugs on the inner top and
bottom faces. These lugs are about 10mm wide by 2mm thick.

Remove the front plastic moulding (Item 13). Care must be taken not to damage the cable
assemblies fixed to the front plastic.

Turn the FileStore unit over so that it rests on its top cover and the top faces of the
plastics.

Insert a flat screwdriver between the base of the metalwork and upper face of the plastic
approx. 25mm from one corner. Exert a small force to lift the plastic away from the
metal.

With a second flat screwdriver repeat this action at the centre. See Fig 8.

Remove the first screwdriver and repeat the exercise at the remaining corner. The plastic
will still be connected to the FileStore by flying leads to the LEDs.

Remove the side plastic (Item 18).

Turn the FileStore unit the correct way up.

Lever the top of the plastic away from the metal.
(5)
Remove the top cover (Item 14). This is fixed by six Posidriv screws (Item 61) through
the base of the unit.
Warning
Before continuing disassembly of the rest of the unit ensure that full anti-static
procedures are taken.
(6)
The top cover will now slide off the rear of the unit.
