Hardware Description
Network
This section discusses the hardware and software
components that make up a typical VIASYS network.
A VIASYS network consists of two or more systems
connected to a hub or switch via a category 5 UTP
cable. A network stops being just a VIASYS network
when there is an additional connection to a hospital
backbone or Information System.
The network “functional unit” consists of hardware and
software components:
• Network Interface (often built onto the
motherboard)
• Ethernet Category 5 cable (UTP)
• Ethernet 100 Mbit Hub
• Microsoft Networking Services and Protocols
NOTE:
Refer to the Appendix for system component part
numbers.
Hardware Components
Network Interface
On D865GLC platforms, the network interface is built
onto the computer motherboard.
Cables and Hubs
The cabling topology generally used for VIASYS
systems is ethernet UTP. The maximum cable length for
this topology is 100 Meters (300 ft.) The other pertinent
rules are:
• The speed of the network will be determined by the
slowest component.
• There is a maximum of 205M between the farthest
communicating systems, using a hub.
Hardware Setup
Software Components
VIASYS XP-based systems require no additional
software components to communicate over a network.
The Windows XP operating system takes care of all
network communication. Refer to Chapter 5: System
Procedures for detailed information on setting up a
VIASYS network.
Step Action
1. Plug one end of the network cable into the
system’s network card and the other end
into a numbered port on the hub. Some
hubs/switches have an Uplink port; systems
should not be plugged into this port.
2. With the systems and the hub powered on,
verify the Link indicator lights on the hub
and network cards are illuminated
3. If plugging into a wall jack instead of a hub,
make sure the port is active. You may need
to involve the IS department for this step.
