Chapter 3 – Computer Update and Card Installation Steps
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 I T3E chassis' circuit
boards and any of its components.
6. Remove the PCIe card from its packaging, handling the
card by its edges and without touching any components
or gold connector pins.
7. Holding the card with its bracket on the left and the connector pins
facing away from you, line up its connector with the slot, and then
gently but firmly insert 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 4).
8. Secure the card using the screw you
removed previously; do not overtighten
the screw (Figure 4).
9. If the PCIe card you installed included a
daughter card, connect them together
with the cables included with the PCIe card,
and then install the daughter card into the Echo
chassis. Secure the daughter card with the screw that
previously secured the port access cover.
10. Place one hand on top of the outer case, and then gently push the inner
assembly back into the outer case (Figure 5).
11. Turn the Echo Express SE I T3E chassis upside-down, and then secure
the outer case to the inner assembly by reattaching the four feet; do
not overtighten the screws (Figure 6).
