When you replace a cable and either install or move an enclosure, be sure to update information
on the labels at both ends of the cables.
Internal Interconnect Cables
Integrity NonStop NS1000 systems predominantly use multimode fiber-optic (MMF) cables for
ServerNet interconnection of:
• Blade elements to the VIO enclosure
• VIO enclosure to VIO enclosure
• VIO enclosure to Fibre Channel disk module (FCDM)
• VIO enclosure to ESS disks
MMF cables are usually orange with a minimum bend radius of:
• Unsheathed: 1.0 inch (25 millimeter)
• Sheathed (ruggedized): 4.2 inch (107 millimeter)
You can use fiber-optic cables available from HP, or you can provide your own fiber-optic cables.
If you provide your own fiber-optic cables, follow the appropriate HP specification for the type
of cable you provide. You can obtain the specification from your HP product representative.

Verify that the link does not exceed the maximum allowable loss. Use a calibrated optics power
source to measure the optics power at the distant end of the cable and then calculate the
attenuation. Loss of 10.5 db or less is acceptable. Attenuation above 10.5 db might appear to
work, but the bit error rate might be unacceptable and require repairing or replacing the cable.
Fiber-optic cables use either LC or SC connectors at one or both ends. This illustration shows the
connector pair for an LC fiber-optic cable:
