IP Address Assignment
Each ShoreGear voice switch requires one IP address. Each software server must be
configured with a static IP address. You can use one of the following to serve an IP

• The BOOTP server integrated into ShoreWare Director
• The maintenance port on the front of the ShoreGear-120/24, ShoreGear-60/12,
ShoreGear-40/8, ShoreGear-T1, or ShoreGear-E1
