NonStop NS14000 Planning Guide (H06.10+)

Each label conveys this information:

Identifies the node number. One node can include up to

six cabinets.

Identifies the cabinet number within the node.

Identifies the offset that is the physical location of the

component within the cabinet. n is the lowest U number

in the cabinet that the component occupies.

All but LSU: Identifies the slot location and port connection

of the component. LSU: Identifies the position of the logic

board and optics adapter pair and the port connection of

the optics adapter.

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.

Cable Management System

Integrity NonStop NS14000 systems include the cable management system (CMS) to protect all

power, fiber-optic, and CAT5 Ethernet cables within the systems. The CMS maintains a 25

millimeter (1 inch) minimum bend radius for the fiber-optic cables and provides strain relief for

all cables.

Several Integrity NonStop NS14000 enclosures, specifically the NonStop Blade Element and LSU,

integrate CMS provisions for routing and securing the fiber-optic cables to prevent damaging

them when the enclosures are moved out and back into the cabinet for servicing.

Additionally, cable spools mounted on the inside of the cabinet structure provide the means for

looping and containing free lengths of fiber-optic cables to prevent damage.

Internal Interconnect Cables

Integrity NonStop NS14000 systems use predominantly multimode fiber-optic (MMF) cables for

ServerNet interconnection of:

• NonStop Blade Elements to LSU

• LSU to 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
