Add I/O Cards
The rp7400 server has 12 expansion I/O slots accessible through side panels on the rear of the SPU chassis.
Six slots are located on each of the two sides.
Slots 3 through 12 are “TwinTurbo” slots supporting 66MHz, 64-bit I/O cards. Slots 1 and 2 are “Turbo” slots
supporting cards with lower speed and bandwidth. If higher speed cards are installed in slots 1 or 2, they will
function but their performance will be reduced. Similarly, slower cards can be installed in slots 3 through 12,
but their performance will not be improved.
There are two configuration rules to consider:
• Load the slowest cards in slots 1 and 2.
• When possible, balance the total number of PCI cards between the two sides. E.g., when adding four PCI
cards, install two on the right (slots 1 through 6) and two on the left (slots 7 through 12).
CAUTION If you are installing the A3783A 10/100Base-TX LAN card, do not connect any type of MAU
transceiver to the AUI connector while the system is powered up. Doing so will cause power to
be shut off to the I/O slot and will generate a High Priority Machine Check (HPMC) error.
If you are going to connect a MAU transceiver to this card’s AUI connector, make sure the
system is powered down first. When the system is powered back on, this connection will then
not generate an error condition.
Refer to the instructions shipped with this LAN card for further information.
