246 IBM Eserver i5 and iSeries System Handbook
Two cables must be ordered to attach to the HSL or HSL-2 ports. When ordering
cables to connect to the HSL interface, optical HSL, copper HSL, copper HSL-2,
or copper HSL to HSL-2 cables are required. An HSL loop uses all optical or all
copper ports and cables. A copper loop can intermix I/O towers or units with
copper HSL and copper HSL-2 ports. Select the appropriate cable based on the
type of HSL ports to which it is being attached, and the cable length required.
One SPCN cable is required for each tower.
#5107 30 Disk Expansion
The #5107 is a disk unit expansion enclosure feature for the #9094 Base PCI I/O
Enclosure. The #5107 includes two 15 disk unit enclosures, one 840-watt power
supply, backplanes, and cables.
A #2757 PCI-X Ultra RAID Disk Controller or #4748/#4778 PCI RAID Disk Unit
Controller or #5703 PCI-X RAID Disk Unit Controller is required to support the
disk units in each of the two disk unit enclosures included with #5107. Each
group of 15 disk units is further divided into three groups of five disk units with
each group of five disk units supported on a separate SCSI bus. A minimum of
two disk unit controllers and a maximum of six are required to support 30 disk
units.
#8094 Optional 1.8 M I/O Rack
The #8094 is a optional base I/O rack shipped on the Model 890 instead of the
#9094 Base PCI I/O Enclosure. The #8094 supports up to 90 disk units, up to 22
PCI IOAs, and up to three additional removable media units. A #8094 is a 1.8 M
rack with two enclosures.
The bottom enclosure is a #9094 Base PCI I/O Enclosure with side covers
and casters removed and a #5107 30 Disk Expansion included in the base
(no feature code required). The #5114 Dual Line Cords - Tower is a
mandatory feature for the #9094.
The top enclosure is a #5094 PCI-X Expansion Tower with side covers and
casters removed and a #5108 30-Disk Expansion Feature (no feature code
required) included in the base. (#5115 Dual Line Cords - Tower feature code
is required for dual line cords in the top enclosure).
The #0694 #5094 Equivalent is a prerequisite.
