Planning20 Installation ManualUnit NameUse the Unit Name field to record a name to be associated with each network unit (i.e.,Gateway) in the Maintenance Console Software. Although the Maintenance Console Softwarerequires this information before a unit can be defined and configured, it is used for unitidentification only and is not recorded in the unit's configuration file (OFDD.VHO).The Unit Name field allows for the entry of an unrestricted alphanumeric string.In the sample worksheet the unit names are combination of office name and numbers (e.g.,NY01, NY02, etc).Unit IP Address (VHUB_IP)Use this field to record each network unit's unique IP address.This address must conform to Internet Protocol addressing requirements, e.g.nnn.nnn.nnn.nnn, where nnn is a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255.The default setting is 192.168.1.200.IP addressing information is typically supplied by a network administrator.Subnet Mask (VHUB_SUBNET)Use this field to record each network unit's Subnet Mask IP address.This address must conform to Internet Protocol addressing requirements, e.g.nnn.nnn.nnn.nnn, where nnn is a value of 1 to 255 excluding 0.0.0.0 and 255.255.255.255.The default setting is 255.255.255.0.Subnet IP addressing information is typically supplied by a network administrator.Route IP Address 1 (GW_IP)*1Use the Route IP Address 1 field to record the IP address of the primary gateway to beassociated with each of the network units.For each unit, the unit's Gateway 1 (i.e., primary Gateway) is the one that will be accessed bythe unit during normal operation.The KX-TDA0480's gateway is typically a router or similar device. This address must conformto Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn is a value of 0to 255 excluding 0.0.0.0 and 255.255.255.255.There is no default value.IP addressing information is usually supplied by a network administrator.• The IP and Gateway addresses must belong to the same Subnet. The unit will not operateproperly and the alarm lamp will be lit when these values are incompatible. Although theMCS rejects conflicting addresses, care must be used if the VHUB_SUBNET parameter isconfigured manually, using the KX-TDA0480 on-line commands.*1 The Gateway is the unit's link to Wide Area Network. The GW-IP refers to the IP address of the device (e.g., a router or similardevice) to which the KX-TDA0480 forwards data packets for delivery to the IP network and from which the KX-TDA0480receives data packets. In the case of an installation behind a firewall, this address is used to route the KX-TDA0480 data throughthe protection facilities. See Appendix A5 and the KX-TDA0480 Programming Guide for details regarding installation behinda Firewall.
