Handling PCI Cards
Overview 1-3
N O T E
The U915 and U916 PCI cards are nearly identical,
differing only in that (1) the U915 accommodates both 3.3-
and 5-volt planes while the U916 accommodates 5-volt
only but includes a 5-to-3.3 voltage regulator, (2) the
U915 requires a different ferrite bead (see “Cabling
Specifications” later in this chapter), (3) the U915 cannot
be used in a Continuum system, and (4) Stratus has not
obtained a common language equipment identifier (CLEI)
for the U915, which means it may not used in the United
States. (The U916 does have a CLEI and may be used
anywhere.). Otherwise, all instructions in this guide apply
to both the U916 and U915 PCI cards.
Handling PCI Cards
PCI cards are extremely sensitive to electrostatic discharge. To avoid damaging a PCI
card during handling, take the following precautions.
C A U T I O N
Do not walk around carrying a PCI card that is not in its
static-protective envelope. Static electricity can damage
the card.
•
Always store the PCI card in its static-protective envelope if it is not installed
in the system.
•
Always hold a PCI card by its edges.
•
Always ground yourself before handling a PCI card. To ground yourself, touch
the inside of the PCI card cage to discharge any static electricity, or you can
wear a grounding strap. If you have a grounding strap, attach one end to the
rear of the system, and place the other end around your wrist. Figure 1-2
shows the location of the grounding-strap jacks in a Continuum Series 400-CO
system. (For a Netra 20/T4 or SunFire V480 series system, see the
documentation that came with the system.)
