Verify basic server hardware. It is important to verify all basic hardware configurations to make sure there are no issues before going into the lenghthy and time-consuming steps of software installation.

The following step verifies basic processor (cpu) information such as the cpu speed, cache size, and the number of processors. Processors with duo and quad cores must show two- or four-processor sections, respectively. You do not need to have root access to perform this step.

The following step verifies the network interface. Most dedicated servers use only one network interface adapter to serve multiple IP addresses. Servers in high-availabilty or clustering environment often use more than two network interfaces.



The following example shows a scenario that binds three static IP addresses to one network interface (eth0). If your server has more than one network interface adapters, you need to check for separate sections of eth1, eth2, etc. If there are errors either in the receiving (RX) or transmitting (TX) packets, or if there are any packet collisions present, you will need to resolve these issues with your hosting provider before proceeding to the software installation step.
