4.5.5.2 Installing a Graphics (UPA) Card
1. Use the procedures described in Section 4.5.2 “Removing a Board,” to remove the
applicable G I/O board.
Note – The connector pins on graphics (UPA) cards are extremely delicate, use care
when handling.
2. Attach a wrist strap and take the graphics (UPA) card out of the protective
packaging and place the card on an antistatic mat.
Inspect the pins in the connector to make sure they are not bent.
3. Remove the adapter bracket from the rear panel of the card (
FIGURE 4-16
).
Remove the two screws securing the adapter to the card rear panel (the adapter
bracket and the screws are not needed for this installation).
4. Locate the UPA connector for the card (
FIGURE 4-21
).
5. If a filler panel covers the back panel slot for the graphics (UPA) card, remove the
two screws and detach the filler panel.
Retain the screws to attach the graphics (UPA) card to the back panel, unless the
card has a wide connector, or set of connectors.
6. Unlock the two standoffs for the UPA connector slot (
FIGURE 4-14
).
7. Hold the card at an angle and guide the card face plate under the springfingers
and against the rear face of the G I/O board front panel.
The I/O connectors of the card should be visible through the opening in the
G I/O board front panel.
8. Hold the card by the edges nearest the UPA connector and position the card over
the two standoffs.
9. Hold the card by the edges near the connector and firmly but gently press the card
down until the connector is fully seated.
To align the connector and socket, push the card toward the G I/O board
front panel.
Caution – Graphics (UPA) cards have very fragile connectors. Press gently to
ensure pins do not break or bend.
Caution –
Do not rock the card onto the socket; the plastic connector housing may
break.
