Which architecture to choose?

      So that your MGE UPS SYSTEMS UPS protects several computers, some examples of software and hardware architecture are given below. These typical examples using a UNIQUE agent and SEVERAL clients can help you to build your own architecture.

      THE AGENT:

      Your MGE UPS SYSTEMS UPS must first be connected DIRECTLY to ONE AGENT ONLY. This agent can be:

      • a software agent ( UM-Agent )
      • an embedded agent internal to the UPS.
      • or an embedded agent external to the UPS.

      These three types of agent are not connected in the same way, as shown by the following diagrams:

      • Connection example for UM-Agent:


      Note on this diagram the three types of connection essential to ensure that the agent operates correctly:

      the RS232 link

      the power supply

      the TCP/IP-SNMP communication network
      • Connection example for an internal embedded agent:

      Note on this diagram the only type of connection essential to ensure that the agent operates correctly:

      the TCP/IP-SNMP communication network
      • Connection example for an external embedded agent:

      Note on this diagram the three types of connection essential to ensure that the agent operates correctly:

      the RS232 link

      the power supply

      the TCP/IP-SNMP communication network

      THE CLIENTS :

      To ensure complete protection for the various hardware devices connected to the TCP/IP-SNMP network, the correct connections must be made and the protection module ( UM-Client ) installed on each.

      Each UM-Client module communicates via TCP/IP-SNMP with the agent, and initiates the computer shutdown procedure on reception of secured traps from the agent.

      Depending on the type of agent you have chosen, you will obtain one of the following three architectures:

      • The exchanges between the UM-Agent and the UM-Clients take place on this type of architecture:

      Note on this diagram the three types of connection essential to ensure that the agent operates correctly:

      the RS232 link

      the power supply

      the TCP/IP-SNMP communication network
      • The exchanges between the internal embedded agent and the UM-Clients take place on this type of architecture:

      Note on this diagram the two types of connection essential to ensure that the agent operates correctly:

      the power supply

      the TCP/IP-SNMP communication network
      • The exchanges between the external embedded agent and the UM-Clients take place on this type of architecture:

      Note on this diagram the three types of connection essential to ensure that the agent operates correctly:

      the RS232 link

      the power supply

      the TCP/IP-SNMP communication network
      • UM-Console (+)

      From each of the computers connected to the TCP/IP network you can display the UPS characteristics.

      Remark: If you have several UPSs connected to different types of agent (for example an internal embedded agent for a Pulsar and a UM-Agent software agent for a Galaxy, your global architecture will be a combination of the examples presented above.

      Now you have chosen your software and hardware architecture, you must set up your UPS connection .
