AR725 LEDs and what they mean
Functions of the AR725’s LEDs are shown in the following table. 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.

|
|
| ETH | These LEDs give indications about the Ethernet interfaces.There are two LEDs for |
|
| each Eth port. |
|
|
|
| L/A (Link/Activity) | Lit green when the Ethernet interface is connected to a device (e.g., a hub), which |
|
| is generating link pulses. Blinks yellow when data is being transmitted or received |
|
| on the Ethernet interface. |
|
|
|
| 100M | Lit when the Ethernet interface is in 100 Mbps mode. |
|
|
|
| PIC0/PIC1 | Lit when a PIC is inserted in either PIC bay 0 or PIC bay 1 (one LED for each PIC). |
|
|
|
| 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. |
|
|
|
System | SYS | This LED is not normally lit. It is used to signal various system conditions (e.g., |
|
| when the processor executes the reboot sequence). Generally it signals a possible |
|
| fault condition, but it is lit during a |
|
| remains lit until a software version has been loaded from flash memory. |
|
|
|
Security | SEC | Lit when a user is logged in with SECURITY OFFICER privilege and the router is in |
|
| SECURITY MODE. |
|
|
|
Activity |
| Lit when the compact flash card is accessed. |
(Compact Flash) |
| Do not remove the compact flash card when the LED is lit. |
|
|
|
| ENGINE | These LEDs give indications about PAC (PCI Accelerator Card), which can be |
|
| installed for encryption and/or compression purposes. |
|
|
|
| ACT | Lit when a PAC is installed in the PAC slot. |
|
|
|
| DAT | Lit when data is transferred to or from the PAC. |
|
|
|
| ERR | Lit when there is an error in the data transmission to or from the PAC. |
|
|
|
Clear | CLR | Lit when a secure router has enabled PPP interfaces or Frame Relay circuits that are |
|
| configured to send clear text. |
