i5/OS V5R4 supports the use of all of the preceding hardware elements except one slimline slot,
two serial ports, and two USB ports. These components are reserved for other operating
systems running on the model 525.
Neither the integrated controller nor the integrated Ethernet adapter, which drives the two
Ethernet LAN ports, uses any of the six PCI-X slots. You can add 40 MB write cache to the
integrated disk controller for a disk performance boost and to enable RAID-5 capability and still
require no PCI-X slot. An IOP or ECS WAN adapter can be included as part of the edition
definition. Each uses one of the six PCI-X slots.
The model 525 system unit supports hot-plug disk slots, hot-plug PCI-X slots, and redundant
hot-plug cooling fans. An optional redundant hot-plug power supply is available.
Order the model 525 as a 9406-525. It comes with a one-year hardware warranty with 24 x 7 and
same-business-day service.
The model 525 system unit can be greatly expanded using I/O expansion towers/drawers that
include additional PCI slots and disk slots. Up to six I/O towers/drawers can be attached via a
high speed link (HSL) loop. In addition, Integrated xSeries Adapters can be located on the HSL
loop, providing IBM System x integration.
