NonStop NS16000 Series Planning Guide (H06.11+)
These restrictions or requirements apply when integrating NonStop S-series I/O enclosures into an
Integrity NonStop NS16000 series system:
• Only NonStop S-series I/O enclosures equipped with IOMF 2 CRUs can be connected to an
Integrity NonStop NS16000 series system. The IOMF 2 CRU must have an MMF PIC installed.
NonStop S-series system enclosures can be converted to NonStop S-series I/O enclosures,
replacing the two PMF CRUs in each enclosure with IOMF 2 CRUs. See the conversion
instructions in the Hardware Service and Maintenance Publications category of the Support
and Service Library of NTL.
• Disk drives and ServerNet adapters (except SEB and MSEB CRUs) used in NonStop S-series
I/O enclosures, as well as devices that are downstream of these enclosures, are compatible
with NonStop NS-series hardware. For information about the disk drives and adapters, see
the manual for that disk drive or adapter.
CAUTION: Do not attempt to use NonStop S-series SEB or MSEB CRUs in NonStop S-series
I/O enclosures connected to Integrity NonStop NS16000 series systems. System failures can
result.
• Connection to a NonStop S-series I/O enclosure cannot be on the same p-switch PIC that
connects to an IOAM enclosure.
• Each p-switch (for the X or Y ServerNet fabric) has up to six I/O PICs, with one I/O PIC
required for each IOAM enclosure in the system. Each NonStop S-series I/O enclosure uses
one port on one PIC, so a maximum of 24 NonStop S-series I/O enclosures can be connected
to an Integrity NonStop NS16000 series system if no IOAM enclosure is installed.
• Assignment of the group number of each NonStop S-series I/O enclosure depends on the
cable connection to the p-switch PIC by slot and port as described in “NonStop S-Series I/O
Enclosure Group Numbers” (page 29). Only NonStop S-series I/O enclosures with these
group numbers can be connected to an Integrity NonStop NS16000 series system:
◦ 11 through14
◦ 21 through 24
◦ 31 through 34
◦ 41 through 44
◦ 51 through 54
◦ 61 through 64
For NonStop S-series I/O enclosures that have a nonsupported group number, change
the group number as described in the NonStop S-Series Planning and Configuration
Guide.
• Cables required are:
An LC-SC multimode fiber-optic cable connects each IOMF 2 CRU to a p-switch in an
Integrity NonStop NS16000 series system.
◦
◦ A serial cable from each SPON connector on the p-switch carries power-on signals to
the NonStop S-series I/O enclosure. This is a unidirectional SPON cable used only for
connection between a a p-switch in an Integrity NonStop NS16000 series system and
the IOMF 2 CRU in the NonStop S-series I/O enclosure.
◦ If the system has no IOAM enclosures and you want system communications with the
OSM Service Connection and OSM Notification Director, the NonStop S-series I/O
enclosure must provide connection for the dedicated service LAN via two Category 6
(CAT 6) Ethernet cables. Category 5e (CAT 5e) cable is also acceptable.
