Port Status Leds - HP 650 Installation Manual

N o t e
Self-test appears green when the self-test is in progress, when there is a
failure of the corresponding module after the self-test, or when the corre-
sponding inteface card is not properly installed. The Self-test LED for
the routing engine appears green when there is a failure of either the
routing engine, any interface card, or some other part of the router. For
more information, refer to chapter 3, "Troubleshooting."

Figure 2-3. Port Status LEDs
For most interface cards, the 3rd through 18th LEDs are used to indicate
the port status, as described in this section. If a particular interface card
uses these LEDs differently, its documentation will describe that use.
There are four port status LEDs for each of the four ports.
Port Number indicates the number of the port, 1–4. The number
appears green during the self-test and when the router is operating
normally.
Rx flickers green as packets are being received through the correspond-
ing port. The frequency of the flickering indicates the amount of traffic.
In heavy traffic, it may appear as if it is lit all of the time.
Tx flickers green as packets are being transmitted through the
corresponding port. The frequency of the flickering indicates the amount
of traffic. In heavy traffic, it may appear as if it is lit all of the time.
Net Fail appears orange when either the corresponding port or the
attached network has failed during a self-test or during router operation.
