planned outage for 2 of 3 servers in cluster

[kramerr]

we've a 3-server cluster - 1-pub, and 2-subs. We're planning work on switches which will bring down PUB and 1-SUB. Can the remaining SUB-02 take the load of ALL 900 devices during the planned 1-hour outage? Thanks.

What is the CM version and Hardware type ?? Also, what would the call volume be ??

Note that the CM might be able to handle calls, but none of the directory functions would work. No changes can be made to config during this time (including enabling or changing Call Fwd settings, EM login/logout etc).

CCM v 4.2.3 sr16 installed within past week on the latest 7845-H2 MCS. So long as we could handle calls, it seems OK. I understand about the directory not working. Thank you, kind sir.
