5 Using appropriate ESSD precautions, including wearing an anti-static wrist strap, fit the
board in the allocated expansion slot. Align the board with the appropriate slot. Slide the
board faceplate inside the iPS back plane. Lower the board into the iPS until the appropriate
40-way header on the main PCB mates with the PCB connector of the board. Push the
board firmly into the main PCB header.
6 From the rear panel of the iPS, insert the retaining screw to hold the card. Do not tighten at
this time.
7 From the top of the iPS, replace the top retaining bracket and replace its screws. Make any
small adjustments to the card position to ensure that it is seated correctly and the cut-out in
the card face plate aligns with the tongue on the retaining bracket. When the board is
positioned correctly, tighten the retaining bracket screws and the board.
8 Replace the upper retaining screw holding the Helium probe 9 way D connector to the Level
Meter board back plate.
This step only applies to the level meter board.
It is important to ensure that the daughter board retaining screw is correctly tightened in
order to provide a low impedance connection to the
Mercury
chassis for low-noise
measurements and outputs and EMC compliance.
