Rack Interface Module
Removing the metal sleeve
7-4
Caution
The module contains static sensitive components and care must be
taken to ensure that the surface onto which the printed circuit board
assemblies are to be placed and the user are at the same potential.
Standard anti-static precautions should be observed.
If full anti-static precautions can not be observed, personal grounding
may be achieved by touching an earthed metal chassis or component
prior to handling the module.
The metal sleeve must be removed in order to gain access to the motherboard.
(1) Remove the M3 screw and shakeproof washer which retains the printed
circuit board earthing block to the sleeve, from the lower left hand side of
the metal sleeve.
(2) Loosen the two M2.5 nuts retaining the backplane end of the motherboard
to the sleeve.
(3) Slide the motherboard out of the metal sleeve towards the back of the
sleeve.
(4) Fitment is the reversal of the process. However, care should be taken to
ensure that the motherboard is located correctly within the metal tabs (earlier
versions only) inside the sleeve before tightening any fixing.
