Removing or Replacing a U916 PCI Card
C A U T I O N
When you handle a PCI card, always ground yourself to
prevent electrostatic discharge from damaging the card.
In addition, always hold the card by its edges; never touch
the components on the card.
1. Stop any processes or software that are using the U916 PCI card.
2. Shut down (enter
init 0)
and power off the system.
3. Disconnect the cable from the PCI card by squeezing the pinch tab on the side of
the cable connector and gently pulling the cable out of the PCI card.
4. Remove the chassis cover to expose the PCI cards.
5. Touch the side of the chassis to discharge any static electricity (see your Netra
20/T4 or SunFire V480 series documentation).
6. Identify the slot from which you intend to remove the PCI card (see “Netra System:
Locating the PCI Card Slots” or “SunFire System: Locating the PCI Card Slots”
earlier in this chapter).
N O T E
Due to the heat generated when the system is running, a
PCI card may feel warm when you remove it. The PCI card
will cool if you wait for two minutes after shutting down the
system before you remove the card.
7. Remove the retaining screw that secures the card at the rear of the chassis (see
Figure 3-6).
C A U T I O N
To avoid snapping the voltage regulator, position your
hand and thumb above that component as you install the
card.
8. Grasp the top of the card with both hands (remember not to touch the components
on the card). Pull one end of the card outward to loosen it from the backplane
connector, and then pull the other end outward to remove the card from the
connector. When the card is free, gently pull it out of the chassis.
9. Store the PCI card in a static-protective envelope to avoid damaging it. If you are
replacing the PCI card with a new card, see the “Netra System: Installing a U916
PCI Card” or “SunFire System: Installing a U916 PCI Card” section in this chapter
now. If not, proceed to the next step.
