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 power-up or operator initiated reboot, and

 

 

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.
