For further information about this tower, refer to the IBM i5, iSeries and AS/400e
System Builder i5/OS Version 5 Release 3 at the following Web site:

#5294 1.8 M I/O Tower
The #5294 has space for up to 90 disk units, 28 PCI-X IOA/IOP slots, and up to
four removable media units. Two #9844 Base PCI IOPs are included. A #5294 is
equivalent to two #5094 PCI-X Expansion Towers with side covers and casters
removed, and with two 30-disk expansion included (no feature required) and
placed in a 1.8 M tower.
The 90 disk unit positions are controlled by up to 18 OS/400 or Linux controlled
disk controllers.
The #5294 also supports up to four removable media devices (internal tape or
CD-ROM/DVD). These removable media devices are supported by the two
#2757/#4748/#4778 PCI RAID Disk Unit Controllers that support the first two
groups of disk units.
A bus adapter to provide the HSL interface to the system is included. Select two
of the following options:
#6417 HSL-2/RIO-G Bus Adapter (for upgrades only)
#9517 - Base HSL-2/RIO-G Bus Adapter (copper) (for new towers only)
#9876 - Base Optical Bus Adapter (replacement for #9886)
#9877 - Base HSL-2 Bus Adapter (replacement for #9887)
#9887 - Base HSL-2 Bus Adapter to specify two copper HSL-2 ports
#9886 - Base Optical Bus Adapter to specify two optical HSL ports
Two to four 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 and 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.
Copper HSL to HSL-2 (HSL on one end and HSL-2 on the other end)
Note: A #9877 - Base HSL-2 Bus adapter is shipped with new orders of a
#0595 for Models 800, 810, 820, 825, 830, 840, 870, and 890. A #9517 - Base
HSL-2/RIO-G Bus Adapter is shipped for Models 520, 550, 570, and 595.
