We have two 3005 VPN Concentrators. We set them up as Load Balancing. We need to shutdown the VPN Concentrators because the building needs to shutdown the power. What are the orders of shutting down and bringing them back up? Would you bring down the Secondary VPN Concentrator first, then bring down the Primary VPN Concentrator? To bring them up, would you bring the Primary VPN Concentrator first, then the Secondary VPN Concentrator?
