An overview of the interface cards can be found under the heading

Installing Interface Cards starting on page 40.

For each of the two slots, there is a LED on the front panel of the

Forum 524 Rack. These LEDs are labelled SLOT1 and SLOT2. An

LED will show a constant light, if an interface card is inserted into

the corresponding slot and the operating software has detected an

interface card. An LED will blink, if an error condition was

detected.
