PCI and PCI-X expansion towers

Expansion towers provide iSeries servers with the ability to support additional I/O
and disk units. For information about the number and types of towers supported
by each iSeries server, see Chapter 5, "Summary of today's iSeries" on page 81.

#5074 PCI Expansion Tower

The #5074 is attached to Models 520, 550, 570, 595
810, 820, 825, 830, 840, 870, and 890 for adding up to
45 disk units, up to 11 Peripheral Component
Interconnect (PCI) input/output adapters (IOAs), and up
to two removable media units. The #5074 includes the
#9691 Base Bus Adapter or the #9739 Base Optical
Bus Adapter to provide the HSL interface to the system.
The IBM marketing configurator adds onebus adapter
interface #9691(copper) or #9739 (optical) to the order.
The #5074 contains two buses.
Select any two HSL cable features for the first or only
tower of an HSL loop. For additional towers on the HSL
loop, select one HSL cable per tower. A list of the supported HSL cables is shown
in the table on page 299. A list of the supported SPCN cables is shown in the
table on page 299.
The #5074 has a #9943 Base PCI IOP. It also has PCI slots for up to 11 PCI
IOAs, space for up to 45 disk units (15 are "base", 30 additional with #5101),
space for two removable media devices (internal tape, CD-ROM, or DVD-RAM),
one battery backup, and redundant or hot swap power supplies.
The 11 PCI IOAs are supported (driven) by a #2843 PCI IOP, #2844 PCI IOP,
#9943 Base PCI IOP, #2790 PCI Integrated Netfinity Server, or the
#2791/#2792/#2799 or #4710 PCI Integrated xSeries Server.
The #5074 can contain Ultra2 SCSI disk units that are controlled by a
#2757/#4748/#4778 PCI RAID Disk Unit Controller. The removable media
devices are supported by the same #2757/#4748/#4778 which supports the first
set of 15 disk units. A maximum of three #2757/#4748/#4778 PCI RAID Disk Unit
Controllers (any combination) are supported.
The #5074 PCI Expansion Tower supports four 32-bit and seven 32/64-bit PCI
slots.
