SG 650 - Will installing an 8 port GbE SFP Flexi Port module on active/passive SG 650's cause HA to fail due to dissimilar Hardware

Vince Hayes1

Hi,

I'm not sure this is the right forum, as it's XG650, but I couldn't find any group that deal's with SG650's

We have 2 SG650's running UTM9.5, in Active/Passive mode.  All is working okay.  We have also purchased 2 x 8 port GbE SFP Flexi Port modules- one for each firewall.

If we turned both firewall's off, added the modules, and powered them on again, I'm sure the HA would be okay.  However, I was wondering if I could power down the SG650's one at a time to change the modules, leaving the other SG650 active. That way I wouldn't have to take down the network, and just have an "at risk" period instead, at a quiet time.  

My concern would be that after the initial power down , module replacement, and restart of the first SG650, the two SG650's would have dissimilar hardware and would break the HA before we could power down the 2nd SG650 and repeat the process.  

When we first purchased the SG650's we struggled to get the HA working initially, so would be reluctant to break it again.

Many Thanks for your help.

Vince

    Thanks for you comments.  I have seen HA go crazy and may "chicken-out" to take the 15-min outage on the Master active reboot.

    But I may have HA issues by simply powering off the passive unit.  It may be safest to break HA, take the 15min hit and enable HA.

    Sorry for beating this to death - mostly thinking out loud and do appreciate you responding.
