Introduction The two types of enclosures for the 6500 PLUS are:
• Standalone
• Modulus
Standalone
Enclosure A standalone enclosure (Figure 1-1) holds just one card, which must be a processor
card. A standalone unit supports up to six X.25 or terminal ports depending on the
type of processor card installed.

processor cards and several support cards, such as auxiliary processor cards, I/O
cards, or NSO cards (Figure 1-2).
