5486Towr.fm Draft Document for Review October 18, 2004264 IBM Eserver i5 and iSeries System Handbook#5075 PCI Expansion TowerThe #5075 PCI Expansion Tower is attached to Models 270,810, 820, and 825 for adding up to six disk units and up toseven PCI IOAs. The #5075 has a 32 MB PCI IOP (CCIN284B) embedded on the backplane. The #2842 PCI IOP(when attached to a Model 270), the #2843 PCI IOP (whenattached to a Model 820) PCI IOP or the #2844 PCI IOP maybe added. A #4748/#4778 PCI RAID Disk Unit Controller,#2757 PCI-X Ultra RAID Disk Controller, a #2763 PCI RAIDDisk Unit Controller, #2782 PCI-X RAID Disk Unit Controlleror a #9767 Base PCI Disk Unit Controller may be installed inPCI slot C01 to control the disk units. The #9767 supports upto four disk units when installed in the #5075. The #5075contains two buses.Select any two of the supported HSL cables. A list of the supported HSL cablesis shown in the table on page 299.Select one of the following SPCN cables per Model 270 or 820: #1463 - 2m SPCN Cable #1464 - 6m SPCN Cable #1465 - 15m SPCN CableThe #5075 can control Ultra2 SCSI disk units. A maximum of one disk unitcontroller is allowed within a #5075.On new orders, specify one line cord with each #5075 PCI Expansion Tower.Marketing configurators default to the line cord type of the system.When the #5075 is attached to the Model 270 or 810, the seven PCI IOAs aresupported (driven) by an embedded 32 MB PCI IOP and by the #2842 PCI IOP,#2844 PCI IOP, the #2890 PCI Integrated Netfinity Server, or the#2891/#2892/#2899 PCI Integrated xSeries Servers.When the #5075 is attached to the Models 810, 820, and 825, the seven PCIIOAs are supported (driven) by an embedded 32 MB PCI IOP and by a #2843PCI IOP, #2844 PCI IOP, the #2790 PCI Integrated Netfinity Server, or the#2791/#2792/#2799 PCI Integrated xSeries Servers.The #5075 PCI Expansion Tower is not supported on Model 520, 550, 570, 595,830, 840, 870, or 890 servers. When performing upgrades, the #5075 can beconverted to a #5074. Some features in the #5075 are migrated or converted tothe #5074 at no charge. Other features allowed in the #5075 are not supported inthe #5074 and must be replaced. See “Upgrade options for expansion towers” onpage 316 for a further discussion about the #5075 to #5074 feature conversion.#5075 PCIExpansion Tower
