Indicator LEDs on Control Cards

Indicator LEDs on Input, Crosspoint, and Output Cards
The LEDs on the front of the input, output, and crosspoint cards can be monitored to determine
whether the cards are operating normally. The LEDs indicate the following:
Indicator LEDs on Fans
Each fan features two LEDs that indicate if the fan is operating properly. The fan LEDs are not vis-
ible when the router door is closed. However, the control cards monitor taxometers on the fans and
forwards to determine if the fans are spinning and sends this information to the router control sys-
tem. The LEDs indicate the following:
Air Flow
The NV7512 draws cooling air from the front of the router, through the door, and exhausts heated
air through the rear of the frame. The router must have the door properly installed and closed for
proper airflow through the chassis. For maximum air flow, regularly inspect router fans and filters.
