Installing the Hardware
command in global configuration mode) before the operating system can
initialize these power-denied cards. Because the power capacity check is
always performed when line cards are configured from the CLI (using the
card
command or the
port
command in global configuration mode), no cards are
denied power during the power-on sequence unless mismatched controller
cards are installed.
If the active and standby controller versions are different, the operating
system allocates power for both controller cards, initializes them, and issues
a controller mismatch alarm.
The operating system always reserves enough power during system
configuration so that if the system has only a single controller card installed,
it is always possible to install a standby controller card of the same type at
a later time.
To power off the system, remove all fuses in the fuse panel.

Power-On Diagnostics
Power-on diagnostics verify the correct operation of the controller cards,
backplane, fan tray, and each installed line card during a power-on or reload
sequence of the SmartEdge 600 router. These tests also run whenever a
controller or line 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 operating system. 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 line
card. If the system has two controller cards, the controller tests run in parallel.
To display results from power-on diagnostics, enter one of the following
commands in any mode:
