Network Names and IP Addresses
In addition to IP Address, there are several other identifiers given to Network devices so
they can be uniquely identified by the network and in Philips software application windows.
These include the following:
Subnet Mask
Because the last 2 digit sets of the IP Address are the key digits that uniquely identify a
device, a Subnet Mask is applied to the IP Address to "mask" the first 2 IP Address digit
sets. The Subnet Mask used for Philips software is 255.255.0.0. For example, adding the
Subnet Mask to the IP Address of the Database Server gives a "masked" address of
255.255.221.0, where the unique last 4 digits of the Server's IP Address have been added to
the Subnet Mask.
Almost all IP Address handling applications require the specification of a Subnet Mask. The
Subnet Mask default value of 255.255.0.0 is used for all Network connected devices and will
appear in Windows configuration applications. It is not necessary to know the "masked" IP
Addresses of Philips devices, although it does appear in the Network category of the
Status Log. In all other applications, the real IP Address for networked devices is shown.
Default
Default Gateway is another field that must be specified in many IP Addressing applications.
Gateway
The default gateway for all Information Centers and Clients must be set to the Database
Server's IP Address. The default gateway for the Database Server can be set to its default
value.
MAC Address
Media Access Control (MAC) Address is a fixed, unique 12 digit HEX number that
identifies each device. Part of the number identifies the device manufacturer. It is hard coded
into the device's network interface card and cannot be changed. It is not necessary to know
the MAC Addresses of Network devices, although they will appear in some OS application
windows. For instance, if the MAC address of the printer is needed, it is on the configuration
page printed out during the printer installation.
Host Name
Host Name is an alphanumeric name assigned to each workstation -- Information Centers,
Clients, Database Server -- and resides in its software. Philips assigns a Host Name to each
PC before shipment; but it should be changed to a name that identifies its function,
associated unit, and physical location. A Host Name for an Information Center in the CCU
on the third floor, south wing of the hospital might be ICCCU3S. Or the Database Server
might be DBSRM96.
Notes
Rules for Host Name for a device on the Network are:
5-34
Hardware Installation
– must be unique for the Server to identify it
– must be no more than 15 characters
– must use alpha-numeric characters only, no other characters acceptable (no
spaces, hyphens, underscores, etc.)
– cannot begin with a number
– must be changed from factory settings during device installation
