Instructions for Installing the VCOM Module
Step
Action
1
On the rear of the ATLAS 550 chassis, remove the cover plate
covering the slot into which the option module carrying the VCOM
resource module is to be inserted.
If theATLAS 550 option module is already in the ATLAS 550
chassis, simply loosen the thumbscrews at both edges of the
option module faceplate and slide the module out of the chassis.
2
Carefully align the P10 connector on the VCOM resource module
with the J10 connector on the option module.
Using only fingertip pressure, so that neither circuit board bends
or flexes, ensure that the connectors are firmly seated.
Secure the opposite end of the VCOM resource module to the
option module using the screws and standoff posts supplied.
3
Slide the option module, with the VCOM resource module
attached, into the ATLAS 550 chassis until the module is
positioned firmly against the front of the ATLAS unit.
4
Fasten the thumbscrews at both edges of the option module
faceplate. Tighten with a screwdriver.
5
Install any additional modules into the base unit, as specified in
the
