If your F5 products has a Firewall Systems Fireblanket service provided with it then all you need to do is provide us with an RMA or Incident number from F5 and we will enact the Fireblanket service. The Fireblanket service is simply a hardware swap service for faulty product - not a generic support contract. Often the fault is a software issue not a hardware issue. The best way to determine if this is the case is to log the incident with the manufacturer of the product. Once they issue an RMA number you can initiate the Fireblanket Service. To log the incident use the above phone number or go to the support web site. If the unit does not power up at all you can initiate the Fireblanket service without waiting for an RMA number.

• The hours that you are available to work on the problem and any alternative contacts that can work on the problem if you are not available.
• Remote access information, if possible.  Remote access to your network environment is important, because it is the most effective method for collecting information and troubleshooting technical issues. If you cannot provide remote access, F5 Networks Technical Support will work directly with you to resolve the issue over the phone; however, this method can often be more time consuming and may require file transfers, replication, and additional testing.
