text: If you are enabling Remote Support Assistance, ensure that the following prerequisites are 
  met: 
  
  (cid:2) Call Home is configured with a valid email server. 
  
  (cid:2) A valid service IP address is configured on each node on the Storwize V7000. 
  
  (cid:2) If your Storwize V7000 is behind a firewall or if you want to route traffic from multiple 
  
  storage systems to the same place, you must configure a Remote Support Proxy server. 
  Before you configure remote support assistance, the proxy server must be installed and 
  configured separately. During the setup for support assistance, specify the IP address and 
  the port number for the proxy server on the Remote Support Centers window. 
  
  (cid:2) If you do not have firewall restrictions and the Storwize V7000 nodes are directly 
  
  connected to the internet, request your network administrator to allow connections to 
  129.33.206.139 and 204.146.30.139 on Port 22. 
  
  (cid:2) Uploading support packages and downloading software have direct connections to the 
  
  internet. A DNS server must be defined on your Storwize V7000 for both of these functions 
  to work. 
  
  (cid:2) To ensure that support packages are uploaded correctly, configure the firewall to allow 
  connections to the following IP addresses on port 443: 129.42.56.189, 129.42.54.189, 
  and 129.42.60.189.
