iSeries Model 870 233
Draft Document for Review October 18, 2004 5486m870.fm
High-speed link on Model 870
The Model 870 supports up to eight HSL loops, six of which can be optical fiber
HSL loops. The optical fiber HSL loop extends the distance between the Model
870 system unit and the I/O units from a limit of 15 meters prior to V5R2, to a
maximum of 250 meters. The extra length can help to improve data reliability and
protection.
See “High-speed link” on page 293 for information about supported high-speed
link (HSL) cables and HSL loop maximums. You can find further information in
High-speed Link Loop Architecture for the IBM Eserver iSeries Server: OS/400
Version 5 Release 2, REDP-3652, and the HSL Rules presentation, which is
available at:

Model 870 PCI cards and features
The Model 870 is a PCI-based technology system. Since migration towers
cannot attach to the Model 870, System Products Division (SPD) cards in
systems or towers migrating to the Model 870 must be replaced with PCI card
equivalents. Refer to “Hardware no longer marketed by IBM” on page 840 for a
list of SPD functions not supported by PCI adapters.
See the table on page 102 for the number of maximum features supported by the
total system and in the Model 870 system unit. See Chapter 17, “iSeries I/O
processors” on page 319, and Chapter 18, “iSeries I/O adapters and controllers”
on page 339, for full descriptions of the features that are supported. See “Not all
features are supported on all models. Some features may be withdrawn but are
in the table for reference. AIX specific adapters are not described in this book.” on
page 344 for supported Linux Direct Attach features.
Note: You can find line cord and power receptacle specification information on
the Web at:

Note: The placement of PCI cards follows special rules. Refer to “PCI card
technology” on page 340 and PCI Card Placement Rules for the IBM
Eserver iSeries Server Version 5 Release 2, REDP-3638, before you
propose any configuration.
