P-Switch to NonStop S-Series I/O Enclosure Cabling
These restrictions or requirements apply when integrating NonStop S-series I/O
enclosures into an Integrity NonStop NS-series system:
Only NonStop S-series I/O enclosures equipped with IOMF 2 CRUs can be
connected to an Integrity NonStop NS-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 on the CSSI Web. (A link to the CSSI Web is in the
left navigation area of the NTL home page.)
Disks 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 disks and adapters, see the manual for that disk or adapter.
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 NS-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 on page 2-36. Only NonStop S-
series I/O enclosures with these group numbers can be connected to an Integrity
NonStop NS-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 an
Integrity NonStop NS-series p-switch.
Caution. Do not attempt to use NonStop S-series SEB or MSEB CRUs in NonStop S-series
I/O enclosures connected to Integrity NonStop NS-series systems. System failures can result.
