PCI Configuration Guidelines
•
Modules designed for 5.0 V signaling and 33-MHz bus speed can only operate in 5.0 V/33-MHz slots
•
Modules designed for 3.3 V signaling and 66-MHz bus speed can only operate in 66-MHz slots
• Universal PCI modules can operate in all slots (3.3 V and 5.0 V)
• Universal PCI modules operating at 33 MHz placed in a 66-MHz slot will reduce the entire hose to operate at
33 MHz
• Universal PCI modules capable of operating at 66 MHz when placed in a 33-MHz slot will operate at 33 MHz
• PCI hot-plug ready slots are designed to enable PCI modules to be added or removed while the system is
powered and running. Subsequent operating system versions above Tru64 UNIX V5.1A and OpenVMS V7.3
will provide support for hot-plug PCI functionality
PCI Module Descriptions:
• PCI modules listed in this document as 33 MHz or 66 MHz refer to the module’s maximum PCI bus speed.
• Modules that can only operate at 5 V are designated as 5 V – 33-MHz modules.
• Universal PCI modules are designated as 3.3/5 V and can be installed into 33-MHz or 66-MHz slots.
AlphaServer ES45 systems provide four I/O hoses, each is configured differently as illustrated in the
following charts for Models 1B, 2B, and 3B.
