Grounding Options
The recommended grounding method for the SafeGuard Controller is to use the
grounding stud immediately to the left of each power input connector. Connect this stud
to earth ground (for example, a grounded rack).
Recommended Cables
Fiber-optic SFP modules require fiber-optic cables with LC connectors. Depending on the
type of SFP module, use either of the following cables:
■ 1000BASE-LX SFP module: single-mode, 1310 nm, 10-km range
■ 1000BASE-SX SFP module: multi-mode, 850 nm, 550-m range
Copper SFP modules require a Category 5 or better cable with RJ-45 connectors.
Depending on the connected device, you can use either crossover or straight-through
cables. Tab le 8 lists the recommended cable types.
To connect the Ethernet management port on the rear panel, use a Category 5 or better
Ethernet cable with RJ-45 connectors. For connector specifications, see Appendix A,
