This only seems to be necessary with Mac OS X 10.2 "Jaguar" and also under Mac OS X 10.2.1.

If the target disk's icon does not appear, restart the computer. The hard disk of the target computer should become available to the host computer and will appear on desktop. Start up the target computer and immediately press and hold down the T key until the FireWire icon appears on the screen, it will move around, floating on the screen denoting the system is running in FireWire Target Disk Mode.

For example, if you plug your MacBook into your iMac via Thunderbolt, this extention will automatically switch the iMac to Target Display Mode, allowing you to use your iMac as a monitor. Cables are available in lengths from 8" to 10' - if you are going to use FireWire Target Disk Mode frequently, you may find it handy to have a cable already run into position to allow for easy access to your systems. This was designed specifically for people wanting to use their iMacs in target display mode, and works especially well in situations where you want to connect a MacBook to the iMac. The host computer does not need to be turned off.
