6.1 Handling Boards and Assemblies
Caution – The chassis AC power cord must remain connected to ensure a proper
ground.
Caution – The interface board and its modules have surface-mount components
that can be broken by flexing the board.
To minimize the amount of board flexing, observe the following precautions:
Transport the board in an antistatic bag.
Hold the board only by the edges near the middle of the board, where the board
stiffener is located. Do not hold the board only at the ends.
When removing the board from an antistatic bag, keep the board vertical until
you lay it on the Sun ESD mat.
Do not place the board on a hard surface. Use a cushioned antistatic mat. The
board connectors and components have very thin pins that bend easily.
Do not use an oscilloscope probe on the components. The soldered pins are easily
damaged or shorted by the probe point.
6.2 Filler Panels
All empty board slots in Enterprise 3500 systems must have a filler panel installed
for cooling purposes and for EMI protection. Filler panels are inserted into a board
slot with the springfingers facing to the right.
To remove the interface board filler panel from the card cage, unfasten the captive
screws at the top and bottom of the panel.
Grasp the handles to pull the filler panel out.
