7.4 WORKING WITH PRISM SYSTEM NETWORK

INTERFACES

You use the EMS to configure the Prism system for one of the two different modes

listed below, which affects how you configure the network interface of the Network

and Craft ports and how you access the system through the EMS. In each mode, the

Host and its subtended Remotes require the same configuration. Both modes require

a DHCP server, which assigns an IP address to the Host and its subtended Remotes.

•

External Network

mode—is the default mode. The Host and subtended Remotes are

DHCP clients and expect IP addresses to be assigned by an external DHCP server

through a network Ethernet connector. If there is no external DHCP server, the

Host will not be able to communicate with any connected Remotes.

The Host Craft port has a DHCP server that you can use to communicate with the

Host directly. The IP address for the Host Craft port is 192.168.0.1. You can access

the EMS via the Craft port, but if the Network port is not connected to an external

DHCP server, the Remotes will not be visible to you.

•

Built-in Network

mode—

Built-In Network

mode is best suited for when there is no

network to connect to or if the Prism network does not have a DHCP server. In

Built-In Network mode, the functionality of the Network port and the Craft port

are swapped. You connect a laptop to the Host Network port, which is assigned a

default fixed IP address of 10.0.0.1 and all subtended network interfaces obtain a

DHCP address in this same subnet. Alternatively, in Built-In Network mode you

can connect the Craft port to an external DHCP server from which the Craft port

obtains its IP address.

Table 7-1 describes how the system mode affects the IP address for the Host and

subtended Remotes.

Static Mode—You also have the option of giving the devices on your Prism system static

IP addresses.

Contact ADC for further information (see “Contacting ADC” on page 335).

There are potential problems in switching between the External Network and Built- In

Network modes. If

cabled incorrectly your DHCP server could provide private IP

addresses on a public network. Set the

Prism system mode once and then do not change

it.
