OWER SUPPLY B System powered by two power supplies Note that this system for greater efficiency is optimized for power distribution by groups of rows of racks Thus a power supply powers a whole number of rows it supports However in rare cases with long rows or many modules with great consumption in the same row there is the option to add power supplies in the middle of the row dividing the power within this row In this case the power supply added powers only the modules positioned on the right in the same row up to the end or even where there is another power supply added In the rack where the power supply was added in this scheme the W1 jumper must be cut and left lateral connection terminal 5 Vdc must be disconnected collapsed 1 Maximum 8 groups allowed when the DF50 or DF56 power supplies are used DF50 User s Manual In this system DF50 must be its CH1 jumper always configured in R even if it is not in redundant pairs A A mixture of these power supplies with the CH1 configured in R and in E in any DFI302 system is not allowed On DF92 the pair of redundant power supplies must be installed in the first and second slots On DF93 is recommended the placement of the redundant pair in the first and second slots but it can be installed in any slots if necessary The system has diagnostic for voltage level distributed to racks It also supports modules with great power consumption in any pl
