Are there 3Com NBX expansion chassis options for use with the V3000, V5000 and V3001 chassis? 3Com's position is to use the 3Com SuperStack 3 NBX V5000 / V3000 Gateway chassis with the listed chassis for expandability. This free-standing chassis comes with 4 slots, and is equipped with both a back plane and power supply. However, some of our users have notified us that they used their existing 3Com NBX 100 chassis with an 3Com NBX up-link card, with the listed chassis, for expandability as well. Call us at 800-544-0059 if you have any further questions.
