Table 3-1. Status LEDs
LED Indicates
Router Self-test
(green) A self-test of the router module is running. This self-test is run whenever the hub is powered on
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
(orange)
A failure has been found either during a self-test or during router operation.
Hub (LAN) Net Fail
(orange)
A failure has been found in a network connected to the hub, or in the router module or the
SNMP module.
Hub (LAN) Router Rx
(green) This LED blinks each time a packet is received from the hub through the router module’s internal
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
(green)
This LED blinks each time a packet is transmitted to the hub through the router module’s internal
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
(orange) The router module or the attached WAN has failed during a self-test or during operation.
WAN Rx
(green) This LED blinks each time a packet is received from the WAN port; the frequency indicates the
amount of traffic. In heavy traffic, it may appear to be on all of the time.
WAN Tx
(green)
This LED blinks each time a packet is transmitted through the WAN port; the frequency indicates
the amount of traffic. In heavy traffic, it may appear to be on all of the time.
SNMP Mgt Fault
(orange) Either a self-test of the SNMP module is running, or a failure in this module has occurred.
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.
