Configuring for Intelligent UPS and Terminal Concentrator

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Figure 5.8 illustrates a remote management computer with a network connection to an intelligent UPS that also functions as a terminal concentrator.

Figure 5.8   Intelligent UPS and Terminal Concentrator

The servers running Emergency Management Services have two connections to the intelligent UPS/terminal concentrator: an AC power connection and a serial connection that supports the VT-UTF8 convention. The serial connection can be provided by a null modem cable or by a service processor. The number of ports provided by the UPS determines the number of servers that can be supported in this configuration. The remote management computer connects to the UPS over the standard network by using an in-band tool, such as Telnet.

In this configuration, terminal concentrator and intelligent UPS functionality are combined, allowing you to manage multiple servers, as well as remotely control power to them.

This configuration requires physical security between the servers and the intelligent UPS. The network connection requires logical security, as described for the terminal concentrator configuration.

This configuration can provide an economical alternative to internal service processors for legacy computers that do not support service processors.

Advantages of this configuration include:

• Provides much of the functionality of a service processor

• Does not require a new component for each server (as service processors do)

• Supports remote management of multiple servers

• Supports logical security

The primary disadvantage of this configuration is that it requires additional hardware.

This configuration can be used for the moderate remote management example described in "Examples: Selecting Remote Management Tools" earlier in this chapter.
