Appendix L: Legacy Power Supplies - Simplex 4100ES Installation Manual

22 Appendix L: Legacy Power Supplies

This appendix describes the installation of legacy 4100ES power supplies, including the SPS and EPS.
22.1 SPS CPU Bay Overview
22.1.1 RUI+ Master Motherboard
The 4100 Master motherboard has two slots, one is dedicated for the system CPU and the other slot is typically used for 4120 Network,
ES Net network or RS232 cards. The first RUI channel in the system is the master motherboard. The RUI+ feature on this card provides
electrically-isolated power for the RUI channel, giving it greater immunity to crosstalk from other channels.
The card is installed on the PDI, occupying the space next to the power supply.
