3.2 Connecting the Drive to Your PC using Ethernet
This process requires three steps
• Physically connect the drive to your network (or directly to the PC).
• Set the drive’s IP address.
• Set the appropriate networking properties on your PC.
Addresses, Subnets, and Ports
Every device on an Ethernet network must have a unique IP address. In order for two devices to
communicate with each other, they must both be connected to the network and they must have IP
addresses that are on the same subnet. A subnet is a logical division of a larger network. Members
of one subnet are generally not able to communicate with members of another unless they are
connected through special network equipment (e.g. router). Subnets are defined by the choices of
IP addresses and subnet masks.
If you want to know the IP address and subnet mask of your PC, select Start…All Programs…
Accessories…Command Prompt. Then type “ipconfig” and press Enter. You should see something
like this:
If your PC’s subnet mask is set to 255.255.255.0, a common setting known as a Class C subnet
mask, then your machine can only talk to another network device whose IP address matches
yours in the first three octets. (The numbers between the dots in an IP address are called octets.)
For example, if your PC is on a Class C subnet and has an IP address of 192.168.0.20, it can
talk to a device at 192.168.0.40, but not one at 192.168.1.40. If you change your subnet mask to
255.255.0.0 (Class B) you can talk to any device whose first two octets match yours. Be sure to ask
your system administrator before doing this. Your network may be segmented for a reason.
