I've just done my first firmware upgrade on our SR ZD3000's with Secure AP Image Upgrade enabled and after over an hour less than a third of the ~200 AP's had upgraded. All the rest were reporting upgrade failures and retrying. After that I turned Secure upgrade off and all the rest upgraded almost instantly (less than 5 mins).
Is enabling Secure Upgrade supposed to cripple the speed and reliability of AP upgrades? I'm assuming the ZD3000 simply doesn't have the power to upgrade many AP's at once when using this method but I'd love some guidance here. If it really can't handle this process why was it bought to the ZD platform?
Thanks
