2.6 64-bit and 32-bit adapters
IBM offers 64-bit adapter options for the p5-520 and p5-520Q, as well as 32-bit adapters.
Higher-speed adapters use 64-bit slots because they can transfer 64 bits of data for each
data transfer phase. Generally, 32-bit adapters can function in 64-bit PCI-X slots; however,
some 64-bit adapters cannot be used in 32-bit slots. For a full list of the adapters that are
supported on the systems and for important information regarding adapter placement, see

2.6.1 LAN adapters
To connect a p5-520 or p5-520Q to a local area network (LAN), you can use the dual port
internal 10/100/1000 Mbps RJ-45 Ethernet controller that is integrated on the system planar.
Table 2-4 lists the additional LAN adapters that are available for an initial system order at the
time of writing. IBM supports an installation with NIM using Ethernet and token-ring adapters

Note: Previous SCSI adapters are also supported for use in the p5-520 and p5-520Q but
cannot be part of an initial order configuration. If you want to connect existing external
SCSI devices, contact your IBM service representative.
