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 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.
