PREPARATION AND INSTALATION OF RR-94845SL CONVERSION COMPONENTS
Using the 94845SL Instruction Manual for guidance, the RR-94845SL is configured in a similar
manner as the RT-94845SL. Be sure to confirm the CWDM being used for the RR-94845SL is
the MRX-CWDM-8 and the 45 series card being used is the RRX-45-1470. Note that there is a
difference in the fiber patchcord configuration between the RRX-45-1470 and the RTX-45-1490
previously installed. Also note that the RJ45 to RJ12 cables used on the RR-9485SL are
labeled ‘MATRIX’.
