Chapter 3 – PCIe Card Installation Steps
6. Remove and set aside the screw used to secure a PCIe card from the
Echo Express SE chassis' inner assembly (Figure 4).
WARNING:
When handling computer products,
take care to prevent components from being
damaged by static electricity; avoid working in carpeted
areas. Handle expansion cards only by their edges and
avoid touching connector traces and component pins. Also,
avoid touching the Echo Express SE chassis' circuit boards
and any of its components.
7. Remove the PCIe card from its packaging, handling the card by its
edges and without touching any components or gold connector pins.
8. Holding the card with the bracket on the left and the
connector pins facing away from you, line up its
connector with the slot, and then gently
but firmly press the card straight into the
slot; do not rock the card or force the
card into the slot. If you encounter
excessive resistance, check the card's connector and the
slot for damage, and then try inserting the card again (Figure 5).
9. Secure the card using the screw you removed
previously; do not overtighten the screw (Figure 5).
10. Without squeezing it, place your hand on top of
the outer case. Gently push the inner assembly
back into the outer case (Figure 6).
