•Card Slots. Fourteen slots are available for WAN cards (T1/E1/DS1), DSP cards, and the CPU/System Controller card.

•Power Supplies. Two load-sharing DC power supplies. The load sharing feature enables one power sup- ply to take over if the other fails.

•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.

•Reset Button. Enables you to reset the system. This function will be supported in a future release.

•Ground Strap Socket. A ground connection is provided for ESD protection.

•Air Filter. The Air Filter is accessible by opening the lower front panel. You do not have to turn off the chassis. For cleaning, see Chapter 8: Diagnostics/Maintenance.

•Chassis LEDs. The LEDs are indicators as to the status of the four voltage supplies. When these are lit, they indicate the respective voltages are being output from the power supplies. When unlit, the voltage is not being supplied. See Chapter 8: Diagnostics/Maintenance for more information.
