Determining Hardware Status
5-12
SmartEdge 1200 Router Hardware Guide
Table 5-13 lists the equipment LEDs, which indicate the current status of the card.
Table 5-14 lists the facility LED for the OC-192c/STM-64/c card; the loss of signal (LOS) LED indicates
the state of the port.
Display Results from Power-On Diagnostics
Power-on diagnostics verify the correct operation of the controller cards, backplane, fan tray, and each
installed traffic card during a power-on or reload sequence of the SmartEdge router. These tests also run
whenever a controller or traffic card is installed in a running system. The power-on diagnostics for each
component consist of a series of tests, each of which can indicate a component failure.
During each test, the power-on diagnostics display results and status; if an error occurs during the testing
of a card, the test lights the FAIL LED on the failing card but does not stop the loading of the
SmartEdge OS. A failure on the backplane or fan tray causes the FAN LED on the fan tray to light.
The maximum test time is 130 seconds: 60 seconds for a controller card, 10 seconds for the backplane and
fan tray, and 5 seconds for each installed traffic card. If the system has two controller cards, the controller
tests run in parallel.
