P-Switch to NonStop S-Series I/O Enclosure Cabling
See the conversion instructions in the Hardware Service and Maintenance
Publications category of the Support and Service Library of NTL. See Support and
Service Library on page C-1.
•
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.
•
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 5-39. 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 a
p-switch in an Integrity NonStop NS-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
NS-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 5 Ethernet cables.
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.
