    Hello everyone,

    does anyone know if the AOC cable (Aruba 40G QSFP+ to QSFP+ 30m AOC - R0Z24A) works on the Aruba 8400 Switch (I/O slot 8400x 8p 40G QSFP+ Adv Module - JL365A)?

    At the moment the datasheet doesnt mention active optical cables to 8400, just for 8325. 


    #8400

    AFAIK Aruba 8400's QuickSpecs (March, 4th 2019 Version 11) doesn't report any support for AOC options...the very same is true for latest ArubaOS-Switch and ArubaOS-CX Transceivers Guide (6th Edition, January 2019)...OTOH latest Aruba 8325's QuickSpecs (May, 6th 2019 Version 6) instead states that AOCs are supported (R0M44A, R0M45A and R0Z21A respectively 3, 7 and 15 meters 25G SFP28 to SFP28 AOCs).

     

    Consider that Aruba 8400 hasn't an interface card with ports supporting SFP28 (1/10/25Gbps)...so that could be the reason.

    At this time (May, 2019), only the 8325 has been qualified to work with the 40G AOCs:

    • Aruba 40G QSFP+ to QSFP+ 7m Active Optical Cable (R0Z22A)
    • Aruba 40G QSFP+ to QSFP+ 15m Active Optical Cable (R0Z23A)
    • Aruba 40G QSFP+ to QSFP+ 30m Active Optical Cable (R0Z24A)

    Qualification for 40G AOC support on the 8400 will be coming in a future timeframe (sorry, can't commit at this time). 

     

    the 25G AOCs: ONLY supported on the 8325

    • Aruba 25G SFP28 to SFP28 3m Active Optical Cable (R0M44A)
    • Aruba 25G SFP28 to SFP28 7m Active Optical Cable (R0M45A)
    • Aruba 25G SFP28 to SFP28 15m Active Optical Cable (R0Z21A)

    And correct, the 8400 does not have a 25G module, so no support for 25G products on the 8400.
