Configuring for Direct Serial Connection
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
Figure 5.5 illustrates a direct serial connection. Using a null modem cable, you can connect the management computer to the server that has Emergency Management Services enabled. This configuration is the simplest out-of-band configuration.
Figure 5.5 Direct Serial Connection
The management computer runs terminal emulation software that preferably supports VT-UTF8 terminal conventions.
Because null modem connections have no built-in security, this configuration depends on physical security. For more information about planning for security, see "Providing Security for Remote Management" later in this chapter.
This type of configuration has the following advantages:
No need to buy additional hardware
Easiest to set up and configure
Good for situations with very few servers to manage
Disadvantages of this type of configuration include:
Management computer must be in close proximity for physical security
Least robust configuration
Logical security is not supported
Ineffective in situations with many servers to manage
A variant of this configuration might be a server with a service processor that provides the serial connection. If a service processor and firmware console redirection are included in the configuration, you can manage all operating states through the out-of-band connection. If Emergency Management Services is the sole provider of console redirection, you can perform out-of-band management only when the Windows Server 2003 loader or kernel is at least partially running.
With this configuration, you can be ready to quickly connect a laptop to a remotely administered server to perform management tasks.
