9. Cycle power.
Once the IP and subnet are changed, you must cycle power to load the new 
address.
Power can be cycled remotely through the management interface by 
clicking the Diagnostics folder and Controller Restart. This restarts the 
1783-EMS switch and does not restart the controller; all communication 
through the switch is interrupted.
Set the IP Address with 
BOOTP
The 1783-EMS switch ships with the BOOTP client enabled by default. To 
assign an address, use this procedure.
1. Put the switch on a network with a BOOTP server.
2. Cycle power to the switch. 
The 1783-EMS switch attempts to obtain an IP address several times from 
the server before timing out and defaulting to the factory preset address of 
192.168.1.1.
Set the Security
We recommend changing the administrator and read-only password before you 
place the switch in service. 
The administrator password is used for the management interface (HTTP 
session), Telnet, and the FTP interface (used to upgrade the firmware). The user 
name is verified for the FTP session only. The user name for the HTTP session is 
not checked (therefore can be anything). The read-only password is used for read-
only access to the management interface (HTTP session). Change your 
administrative or read-only user name and password as follows.
1. Click the Basic Configuration folder. 
IMPORTANT
The MAC address of the switch is on the Home page.  
IMPORTANT
192.168.1.1 could interfere with another device on the 
network.
