We have cisco ASA5585-X with SSP-20 running in production and we need more power so planning to replace SSP-20 with SSP-60 module but not sure we can just hot swap with SSP-20?

Does ASA5585-X support two different version of SSP running on single chassis? if yes then i can replace them one by one. I didn't find any official doc claim that so asking you folks if you have any experience related this scenario

    One thing I have learned over the years is to never, and I mean never, depend on no outage when adding, removing, or replacing anything in a network device, regardless of vendor or what the vendor claims. There are simply too many things that can and will go wrong. – Ron Maupin Jan 24 at 20:36

Per this document Cisco ASA 5585-X Hardware Installation Guide https://www.cisco.com/c/en/us/td/docs/security/asa/hw/maintenance/5585guide/5585Xhw/overview.html dated December 14 2017:

Note Online insertion and removal (OIR) of SSPs and network modules is not supported at this time. Small form-factor pluggable (SFP/SFP+) transceiver, power-supply module, and fan module OIR is supported.

I also would not expect different SSP modules to work, and odds are a reboot would be required to initialize the data structures, but that's just me guessing, not based on documentation.

  • Thanks, but i heard when you put both SSP on single chassis they act like individual module and no interaction with other SSP in that case why this method not supported? – Satish Jan 24 at 20:23

    fyi, whatever link you posted is broken. – Satish Jan 24 at 20:27
  • @Satish corrected and tested. Thanks! – Darrell Root Jan 24 at 20:33
  • @Satish that’s a question for the vendor, but ASA always emphasized “chassis redundancy” (in other words “buying two for double the price”). Supporting mismatched SSPs while hot swapping hardware is a horrific corner case that has very few customers and large testing requirements, so why allocate development resources? – Darrell Root Jan 24 at 20:38
