Front and Rear Panels
Front and rear panels of the AT-AR740 router with a PIC installed in each PIC
bay, and an AT-AR040 4-PIC NSM installed in the NSM bay, are shown in
Figure 18 on page 44.

LEDs and what they mean
Functions of the AR740’s LEDs are shown in Table 20 on page 44. Additional
rear panel LEDs may be present if a PIC or NSM is installed. Functions of PIC
and NSM LEDs are described in their respective Hardware References.

These LEDs give indications about the Ethernet interfaces.
LNK/ACT Lit green when the Ethernet interface is connected to a device (e.g., a hub) which is
generating link pulses. Lit yellow indicates transmission or reception activity.
100M Lit when the Ethernet interface is in 100 Mbps mode.
BASE
These LEDs indicate the state of the main router unit.
Power PWR Lit when power is supplied and the router is switched on.
Run RUN Lit when the internal processor is executing code. If the processor stops for any reason
(a fault condition), then the LED will not be lit.
