So they have for at least four more months of stuff to install, and then what ? You think they're just going to start buying again ?
What is wrong with these people ? Companies are going to use the kit they bought, and they'll use it for a while before needing to buy more.
This problem has hardly gone away. Only new installations are going to fuel immediate growth for Cisco, so it had better pray that a wave of datacenters are being built right now, otherwise Cisco will just sit on its hands waiting for new orders.
