Cables

What kind of cables are required for connections between a node and a

cluster switch? Connections between the MSEBs in group 01 of each node and the

cluster switches are made using single-mode fiber-optic cables. Connections

between cluster switches using the star topologies also use single-mode fiber-optic

cables. Connections between cluster switches using the layered topology use either

multimode or single-mode fiber-optic cables.

What kind of cables are required for connections between cluster switches?

Connections between cluster switches using the star topologies use only

single-mode fiber-optic cables. Connections between cluster switches using the

layered topology use either multimode or single-mode fiber-optic cables.

What lengths of fiber-optic cables are available for ServerNet clusters?

ServerNet cables are 10 meters, 40 meters, and 80 meters long. A plenum-rated

cable is available in the 80-meter length.

For connections between the cluster switches, single-mode fiber-optic cables up to

five kilometers in length are supported. However, HP does not supply cables longer

than 80 meters

Can fiber-optic cables for other Nonstop™ S-series communications

products be used in a ServerNet cluster? Other Nonstop™ S-series

communications products sometimes use the same type of connectors used for

ServerNet clusters. You must the appropriate multimode or single-mode fiber-optic

cable with the correct connectors.

How are cables connected to a NonStop™ Cluster Switch (Model 6770)?

Single-mode fiber-optic ServerNet cables are connected to the plug-in cards of the

ServerNet II Switch component of the 6770 switch. To extend the ServerNet II

Switch for servicing, you loosen the thumb screws securing the ServerNet II Switch

to the enclosure or rack frame. Then you use the handles to extend the CRU on its

rails until the latches click.

How are cables connected to a NonStop™ ServerNet Switch (Model 6780)?

Single-mode fiber-optic ServerNet cables are connected to the plug-in cards of the

6780 Switch.

What are the requirements for using 5-kilometer cables for

connections between cluster switches? To use 5-kilometer cables, all

of the following requirements must be met:

All nodes in the cluster must run G06.16 or a later version of the

operating system.

●

All nodes in the cluster must be S76000 or S86000.●

All processors in all nodes must have the NSR-X or NSR-Y processor

type.
