Installation Overview
Fiber-Optic Cables With LC-SC Connectors
For the ServerNet Cluster product and the IOAM enclosures, LC-SC fiber-optic cables
are used to connect to the MSEBs.
The duplex Lucent connectors (LC) are used to connect to the transceivers on a 6780
switch in the ServerNet cluster product and to the ServerNet switch boards in an IOAM
enclosure. Figure 1-18 shows a fiber-optic cable terminated by an LC connector.
The duplex subscriber connector (SC) connects to a port on the MSEB. For the
ServerNet cluster product, you must install NNA PICs in connector 6 of each MSEB
you plan to use. Figure 1-19 shows a fiber-optic cable with an SC connector.
Cable Lengths
The ServerNet cable lengths for your system depend on how your system enclosures
will be arranged.
Although two enclosure arrangements might be logically equivalent, the cable lengths
required might vary greatly: various enclosure arrangements are possible for the same
configuration. Configurations might be laid out in a single row or multiple rows, and
enclosures might be stacked in different combinations.
You can determine cable lengths for your system in two ways:
•
See the System Enclosure Arrangement Form for your system.
•
See the instructions for determining cable length in the NonStop S-Series Planning
and Configuration Guide.
