Maintenance LAN Cables
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:
Verify that the link does not exceed the maximum allowable loss. Use a calibrated
optical power source to measure the optical 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.
Connections from a p-switch to a Model 6787 cluster switch can use single mode fiber-
optic (SMF) cabling.
Fiber-optic cables use either LC or SC connectors at one or both ends. An LC fiber
cable connector pair follows:
An SC fiber cable connector pair follows:
Maintenance LAN Cables
The system also uses Category 5, unshielded twisted pair Ethernet cables for the
internal maintenance LAN and for connections between the G4SA and the application
LAN equipment.
