4: Installing and Removing Customer-Replaceable Units
Rules for Card Installation and Removal
When installing or removing PCI or PCI-X cards from your system, be aware of the
following rules:
•
If you operate PCI and PCI-X cards on the same bus at the same time, the PCI-X
card will run in PCI mode.
•
If you place cards of different speeds on the same bus, the highest-speed card will
run at the speed of the slower card. For example, if you have a 100 MHz-capable
card in one slot of a bus and a 33 MHz card on the second slot of the same bus, both
cards will run at 33 MHz.
•
When deciding to install a PCI or PCI-X card, be aware that if an IO10 card (a PCI
card that runs at 66 MHz) is installed in your module (in the lowermost slot), and if
you want to install a card in the slot immediately above the IO10, the slot will
operate only in PCI mode at a speed no faster than 66 MHz.
•
Note the following caution when installing or removing a card:
Caution:
Electronic equipment can be irreparably damaged by electrostatic
discharge (ESD). Always follow these preventive measures when you handle a
system component:
- Remove a component from its antistatic bag only when you are ready to install it.
- If you handle a component before installation, do not place it on surfaces that
produce ESD (carpeting, for example) or near devices that create static electricity.
- Attach a static wrist strap to a grounded connection on your system when you
install or remove a component.
