NonStop NS16000 Series Planning Guide (H06.11+)

4 System Configuration Guidelines
This section provides guidelines for Integrity NonStop NS16000 series system configurations.
Integrity NonStop NS16000 series systems use a flexible modular architecture. Therefore, almost
any configuration of the system’s modular components is possible within a few configuration
restrictions stated in “IOAM Enclosure and Disk Storage Considerations” (page 92).
Internal ServerNet Interconnect Cabling
This subsection includes the following topics:
• “Cable Labeling”
• “Cable Management System”
• “Internal Interconnect Cables”
• “Dedicated Service LAN Cables”
• “Cable Length Restrictions”
• “Internal Cable Product IDs”
• “NonStop Blade Elements to LSUs”
• “LSUs to Processor Switches and Processor IDs”
• “Processor Switch ServerNet Connections”
• “Processor Switches to Networking CLIMs” (page 76)
• “Processor Switches to Storage CLIMs” (page 77)
• “Processor Switches to IOAM Enclosures”
• “FCSA to Fibre Channel Disk Modules”
• “FCSA to Tape Devices”
Cable Labeling
Fiber-optic cables provide all ServerNet and other I/O data signal interconnections within Integrity
NonStop NS16000 series systems. With the exception of the dedicated service LAN, no copper
I/O interconnect cables are used. Although fiber-optic cables provide high-speed, low-latency
communications, all of the cables look the same and are the same color, usually orange.
To identify correct cable connections to factory-installed hardware, every interconnect cable has
a plastic label affixed to each end. Extra sheets of preprinted labels that you can fill in are also
provided. These labels are attached to the cable and connector and contain information about
which enclosure and connector the cable is to connect.
This label identifies the cable connecting the p-switches at U31 of both cabinet 1 and 2 at slot 3,
connectors 1 or 2, which are crosslink connections between the two p-switches:
