	SentryPlus software comprised of two modules: SentryPlus 
Service and SentryPlus Monitor. You may run both the programs in 
a computer to monitor your localized UPS or run the programs in 
two different computers.

1. SentryPlus Service with 2 modes: Master and Slave. 

	If there is a communication cable between the computer and 
a UPS, this computer called Master. A Master can monitor and 
control the connected UPS directly, it also transmit the UPS 
information to Slave(s).

	If a computer does not connect to the UPS directly but 
powered by the same UPS, this computer called Slave. Master 
communicates to Slave via a TCP/IP network.

	When a power event occurs, Master(SentryPlus Service) gets 
the information then transmit it to Salve(s)(SentryPlus Service). 
Each SentryPlus Service executes different "Actions"(FlexEvent) 
such that system manager can configure different strategy in 
different computer. For example: When power failed, file server 
and mail server won't shutdown until UPS battery low but some 
unimportant workstations execute shutdown OS after 5 minutes 
the other workstations shutdown after 10 minutes. Shutdown 
workstations preserve more battery power for network servers.

2. Remote Monitor and Control: SentryPlus Monitor.

	SentryPlus Monitor with the ability to monitor Local host 
and Remote host. 

	You can run only SentryPlus Monitor without running SentryPlus 
Service, SentryPlus Monitor will search hosts in the LAN(Local 
Area Network) which runs SentryPlus Service in the combo box. 
Click on the Host Selection combo box will list you the 
searched hosts in the LAN. Select one, then SentryPlus Monitor 
will connect to the selected host.

	If the host located in the internet, you can also input the 
remote host IP address from View - Remote Hosts menu to 
establish the connection.

3. Remote Monitor and Control: Internet Browser.

	Another way to remote monitor SentryPlus Service is using 
Internet Browser. Launch the Microsoft Internet Explorer or 
Netscape Communicator, type the IP address in the URL and press 
enter you will get the UPS information. You can change the 
network port number to prevent conflict with other WEB server 
programs. If the port number isn't 80 you have to type URL like 
this: http://172.16.176.141:2000 where 2000 is the port number 
you assigned.
