Chapter 2  Network Services Setup
DHCP Address Table
The DHCP Address Table is populated when the server is set to assign an IP 
address from a pool. This table details which IP address is assigned to a device (by 
MAC ID).
MAC Address Labels
This lets you associate a user-friendly label to a MAC ID within the 1783-EMS 
user interface. When a label is associated with a MAC ID it is reflected in the 
MAC ID table and the MAC ID management interface.    
This feature eases troubleshooting a network. The labels are reflected in the 
MAC Address Report and the MAC ID Management Configuration page. 
Email Configuration
The 1783-EMS switch includes an embedded email client that uses an email relay 
server or gateway message server to send email and text messages to a mail 
recipient, mobile telephone, or portable wireless device.
The network gateway address and DNS information must be entered. This setup 
is required once and is stored in 1783-EMS nonvolatile memory.  See Set the IP 
Address for help setting up the network addresses.
