MX408e Powered by Part Numbre 1175043L3 AC-to-DC Power Supply

Version 1

    Question: Can the MX408e use the P/N 1175043L3 AC/DC Power Supply for it’s power source?

     

     

    Answer: Yes, but it requires the use of MX2800 power cable P/N 1200657L2 and the following wiring configuration change.

    The MX408e’s backplane has a four-pin power input connection marked A and B each with PWR & RET pins. This requires the

    MX2800 power cable P/N 1200657L2 leads to be rearranged within the four-barrel connector.

     

    The White and Green leads are not used and should be removed from the four-barrel connector. The Red lead is moved to

    replace the White lead and line up with MX408e’s A PWR pin. The Black lead is moved to replace the Red lead and line up

    with A RET pin. This will leave the other two barrels available for the B PWR & RET pins if redundant power input is required.
