1.Modules designed for 3.3V signaling and 66-MHz bus speed cannot operate in Port 0 - slots 2 and 3.

2.In Port 2 of a Standard I/O Drawer, if PBXGG-AA (RADEON PCI Graphics adapter) is installed together with another card instead of 66 MHz, the bus will run at 50 MHz maximum. If RADEON is alone in slot 1, the bus will run at 66 MHz.

3.For Port 0, slots 2 and 3 are keyed for 5V adapters

High Performance I/O Drawer used in ES47, ES80, and GS1280 Systems

All universal or 3.3V PCI and PCI-X cards are supported,

EXCEPT: UltraSCSI wide differential adapter, 32-bit/33-MHz PCI adapter (3X-KZPBA-CC)

PCI-X protocol is used on the bus, but reverts to PCI protocol in these cases:

When a PCI card is in the slot

When Gigabit Ethernet, Rev A (DEGXA-SA/TA) is in the slot
