Router Self-test

A self-test of the router module is running. This self-test is run whenever the hub is powered on

(green)

or reset, and whenever the router module is reset (page 3-5) or cleared (page 3-7). (If initiated by

 

powering on or resetting the hub, the test can last up to 30 seconds if the hub had previously

 

been powered on with the SNMP module installed, or up to 60 seconds if the hub had not

 

previously been powered on with the SNMP module installed. If initiated by resetting or clearing

 

the router module, the test lasts about 18 seconds.) If an error is found during the self-test, the

 

Router Self-test LED remains on, and the Router Fault LED and/or the WAN Net Fail LEDs may

 

also turn on. The Router Self-test LED also turns on during the configuration clearing procedure

 

(page 3-7).

Router Fault

A failure has been found either during a self-test or during router operation.

(orange)

 

Hub (LAN) Net Fail

A failure has been found in a network connected to the hub, or in the router module or the

(orange)

SNMP module.

Hub (LAN) Router Rx

This LED blinks each time a packet is received from the hub through the router module’s internal

(green)

LAN port. The frequency indicates the amount of traffic; in heavy traffic, it may appear to be on

 

all of the time.

Hub (LAN) Router Tx

This LED blinks each time a packet is transmitted to the hub through the router module’s internal

(green)

LAN port. The frequency indicates the amount of traffic; in heavy traffic, it may appear to be on

 

all of the time.

WAN Net Fail

The router module or the attached WAN has failed during a self-test or during operation.

(orange)

 

WAN Rx

This LED blinks each time a packet is received from the WAN port; the frequency indicates the

(green)

amount of traffic. In heavy traffic, it may appear to be on all of the time.

WAN Tx

This LED blinks each time a packet is transmitted through the WAN port; the frequency indicates

(green)

the amount of traffic. In heavy traffic, it may appear to be on all of the time.

SNMP Mgt Fault

Either a self-test of the SNMP module is running, or a failure in this module has occurred.

(orange)

The self-test of the SNMP module, which may last up to 60 seconds, is run when the hub is

 

 

powered on or when the hub is reset. If an error is found in the SNMP module during the self-

 

test, both the Router Self-test LED and the SNMP Mgt Fault LED remain on.
