IBM i Series

Towers and Racks
244 iSeries Handbook
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, one battery backup, and redundant/hot swap power supplies.
The #5074 can contain Ultra2 SCSI disk units that are controlled by a #4748/#4778 PCI RAID
Disk Unit Controller.
The #5074 PCI Expansion Tower supports four 32-bit and seven 32/64-bit PCI slots.
On new orders, select one line cord with each #5074 PCI Expansion Tower.
The 11 PCI IOAs are supported (driven) by feature #2843 PCI IOP or IOPs, #9943 Base PCI
IOP, #2790 Integrated Netfinity Servers or #2791/#2799 Integrated xSeries Servers.
The mounting for the first 15 disk units is included in the #5074 (base). The mounting for the
next 30 disk units is optional by ordering a 30 Disk Expansion, feature code #5101.
The #5074 also supports up to two removable media devices (internal tape, CD-ROM, or
DVD-RAM). These removable media devices are supported by the same #4748/#4778 PCI
RAID Disk Unit Controller, which supports the first set of 15 disk units.
#5105 Dual Line Cord: I/O Tower
The #5105 provides dual line cord capability for the #5074 PCI Expansion Tower and for the
top unit in a #8079 Optional Base Tower. Two 14XX line cords are required for each #5074
tower with a #5101 when a #5105 is on an initial order for a #5074. When ordering a #5105
alone as an MES for a #5074, an additional 14XX line cord is required, for a total of two line
cords on the #5074.
Prerequisite: If the #5074 has feature #5101 (30-Disk Expansion Feature) installed, the
#5101 must be converted to a #5111.
OS/400 V5R1 and supporting are required. Refer to Informational APAR II12950 at:

#5101 30-Disk Expansion Feature
The #5101 is a disk unit expansion enclosure feature for the #5074 Expansion Tower, the
#9074 Base I/O Enclosure, and the #9079 Base I/O Tower. The #5101 includes two 15 disk
unit enclosures, one 765-watt power supply, backplanes, and cables. One #4748/#4778 PCI
RAID Disk Unit Controller is required to support the 15 disk units in each of the two disk unit
enclosures included with #5101. Two #4748/#4778 PCI RAID Disk Unit Controllers are
required to support 30 disk units.
