•Card Slots. Fourteen slots are available for WAN cards, DSP Resource Cards, DS1 cards, and the CPU/ System Controller Card.

•System Fans. Two system fans, accessible through a swing down panel via thumb screws are used to cool the chassis. These fans are “hot-swappable”, meaning you can remove/replace the fans while the unit is operational.
