2.6.1 LAN adapters
To connect a p5-550 or p5-550Q 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
(CHRP is the platform type).

2.6.2 SCSI adapters
To connect to external SCSI devices, the adapters provided in Table 2-5 are available, at the
time of writing, to be configured with a p5-550 or p5-550Q system initial order.
Table 2-5 Available SCSI adapters
There is also the option to make the internal Ultra320 SCSI channel externally accessible on
the rear side of the system by installing FC 4273. No additional SCSI adapter is required in
this case. If FC 4273 is installed, a second 4-pack disk enclosure (FC 6592 or FC 6593)
cannot be installed, which limits the maximum number of internal disks to four. FC 4273 also
requires one PCI-X slot.
For more information about the internal SCSI system, see 2.7, “Internal storage” on page 41.

CHRP stands for Common Hardware Reference Platform, a specification for PowerPC-based systems that can
run multiple operating systems.

Note: Previous SCSI adapters are also supported to be used in the p5-550Q but cannot be
part of an initial order configuration. If you would like to connect an existing external SCSI
device, contact your IBM service representative.
