AR745 LEDs and what they mean

Functions of the AR745’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.

LED

 

Function

 

 

 

Front panel

Rear panel

 

 

 

 

 

ETH

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.

 

 

 

 

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

Lit when the router or management software is malfunctioning. Flashes to indicate fan,

 

 

PSU, and RPS faults.

 

 

1 Flash: A router fan has failed.

 

 

2 Flashes: If an RPS is connected and RPS monitoring is enabled, an RPS fan has failed.

 

 

3 Flashes: If an RPS is connected, the router’s PSU (Power Supply Unit) has failed.

 

 

4 Flashes: If RPS monitoring is enabled, the RPS PSU has failed.

 

 

5 Flashes: If RPS monitoring is enabled, an RPS is not connected or is not operational

 

 

 

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 a PCI Accelerator Card (PAC), 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.

 

 

 

 

NSM

These LEDs give indications about an NSM installed in the router.

 

 

 

 

Swap

Lit when the NSM and its PICs are powered down and can be hot swapped. Only lights

 

 

if the Hot Swap button has been pressed and the software version supports hot

 

 

swapping1.

 

In Use

Lit when an NSM is correctly installed. If the software version supports hot swapping,

 

 

it indicates that the NSM and its PICs are powered up and may not be swapped.

 

 

 

1. AT-AR021 (S) BRI-S/T, AT-AR021 (U) BRI-U, AT-AR022 ETH, AT-AR023 SYN, and AT-AR026 4ETH PICs can be hot swapped.

The AT-AR745 router automatically monitors its own power supply and fan, and has the option of a redundant power supply. If a redundant power supply (RPS) is attached, the AT-AR745 software can detect the presence of the RPS and the state of its output voltages and fan. RPS monitoring, turned off by default, can be turned on or off using the command:

set system rpsmonitor={onoff}
