Towers
218 AS/400e System Handbook
#5079 is essentially two #5074 PCI Expansion Towers, with side covers and casters removed,
placed in a 1.8M tower. Each ordered #5079 counts as two #5074s towards the system model
maximums.
The upper and lower enclosures (#5074s) in the #5079 are not connected with an HSL cable.
If both enclosures of the #5079 are to be placed in the same HSL loop, a #1460 3m Copper
HSL cable must be ordered to connect the upper and lower enclosures.
The #5074 is the default when a PCI IOP or IOA is ordered that requires a PCI expansion
unit. The #5079 may be specified on the extra controllers screen. For each #5079 ordered, a
quantity of two #0574 (#5074 Equivalent) specify codes is added to the order. If a #5079 is to
be shared between two systems, one #0574 must be removed from the original ordering
system and added to the sharing system, using an RPO (Record Purpose Only) change.
Select two to four (any combination) of the following HSL cables for each additional tower:
• #1460 - 3m Copper HSL cable
• #1461 - 6m Copper HSL cable
• #1462 - 15m Copper HSL cable
Select two of the following SPCN cables per tower:
• #1463 - 2m SPCN cable
• #1464 - 6m SPCN cable
• #1465 - 15m SPCN cable
• #1466 - 30m SPCN cable
#5079 has two #9943 Base PCI IOPs, PCI slots for up to 22 PCI IOAs, and space for up to 90
disk units. The #5079 is capable of controlling Ultra2 SCSI disk units.
On new orders, select two line cords with each #5079 1.8M I/O Tower. Some countries offer
fewer choices of line cords, and some countries are shipped a default line cord type.
The #5079 also supports up to four removable media devices (internal tape or CD-ROM).
These removable media devices are supported by the two #4748 PCI RAID Disk Unit
Controllers which support the first two groups of 15 disk units.
Co-requisite: Two #0574 specify features must be ordered for the tower initial order.
