When SNT401/SNT501, SNT411/SNT511 and S2EN501 are mixed, fiber-optic cable is extendable maximum 50 km.There is a following restriction.
Example:
When combination of SNT401 and SNT501 and that of SNT411 and SNT511 are mixed and the length of cable for SNT401 and SNT501 is 5 km, the length of cable for SNT411 and SNT511 must be as long as 45 km (50 km – 5 km).
RESTRICTIONS AND CAUTIONS FOR MOUNTING
• Combination of SNT411 and SNT511 or that of SNT401 and SNT501 can be placed in the same SCS at the same time.
• Mount a set of Optical ESB Bus Repeater Module for duplex on a pair of continuous slots. The module for ESB Bus 1 is always mounted on a slot with odd number, and the module for ESB Bus 2 on a slot with even number.
• When mounting on SNT10D at 60 to 70 °C, leave two slots next to Power supply module and mount one set in every two slots, and leave two slots between one set SNT11. Unit for Optical Bus Repeater Module (SNT10D) is a unit to install Optical ESB Bus Repeater Modules. Refer to “Unit for Optical Bus Repeater Module (Rack Mountable Type)” (GS 32Q06K11-31E).
• For restrictions regarding mounting S2SC70, SSC60, SSC50 and SNB10D, refer to “ProSafe-RS Outline of I/O Modules (for FIO)” (GS 32P06K60-01EN).
• Serial communication modules (ALR111 and ALR121) cannot be mounted on SNB10D placed more than 5 km away via optical ESB bus repeater module.
