iSeries Model 870 227
Draft Document for Review October 18, 2004 5486m870.fm
A bus adapter is included to provide the HSL interface to the top enclosure.
Select one of the following types:
#9886 - Base Optical Bus Adapter, to specify four optical HSL ports
#9887 Base HSL-2 Bus Adapter, to specify four copper HSL-2 ports
Three or 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.
Specify three or four line cords for the #8094 Optional 1.8 M I/O Rack.
If the top enclosure is to be attached to a different system than what was initially
ordered, remove for Record Purpose Only (RPO) the #0694 - #5094 Equivalent
specify code from the initially ordered system and add it to the target system.
A schematic of the #8094 Optional 1.8 M I/O Rack can be found on page 248.
#5114 Dual Line Cords - Tower
The required #5114 feature provides dual line cord support for the #9094 Base
PCI I/O Enclosure on the Model 870 and 890 and for the lower enclosures of the
#8093 and #8094 towers. With the #5114, the enclosure requires two #14xx line
cords and has two AC input boxes.
