#5075 PCI Expansion Tower
The #5075 PCI Expansion Tower is attached to Models 270,
810, 820, and 825 for adding up to six disk units and up to
seven PCI IOAs. The #5075 has a 32 MB PCI IOP (CCIN
284B) embedded on the backplane. The #2842 PCI IOP
(when attached to a Model 270), the #2843 PCI IOP (when
attached to a Model 820) PCI IOP or the #2844 PCI IOP may
be added. A #4748/#4778 PCI RAID Disk Unit Controller,
#2757 PCI-X Ultra RAID Disk Controller, a #2763 PCI RAID
Disk Unit Controller, #2782 PCI-X RAID Disk Unit Controller
or a #9767 Base PCI Disk Unit Controller may be installed in
PCI slot C01 to control the disk units. The #9767 supports up
to four disk units when installed in the #5075. The #5075
contains two buses.
Select any two of the supported HSL cables. A list of the supported HSL cables
is 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 Cable
The #5075 can control Ultra2 SCSI disk units. A maximum of one disk unit
controller 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 are
supported (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 PCI
IOAs are supported (driven) by an embedded 32 MB PCI IOP and by a #2843
PCI 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 be
converted to a #5074. Some features in the #5075 are migrated or converted to
the #5074 at no charge. Other features allowed in the #5075 are not supported in
the #5074 and must be replaced. See “Upgrade options for expansion towers” on
page 316 for a further discussion about the #5075 to #5074 feature conversion.
