LED state
Meaning Action
Off Off The slot is empty or the system
thinks that the slot is empty
because the system didn’t detect
the board when it was inserted. If there is a board installed in this slot, then one of
the following is faulty:
• the board installed in the slot
• the alarm card
• the system controller board
Remove and replace the failed component to clear
this state.
Blinking Off The board is coming up or going
down. Do not remove the board in this state.
On Off The board is up and running. Do not remove the board in this state.
Off On The board is powered off. You can remove the board in this state.
Blinking On The board is powered on, but it
is offline for some reason (for
example, a fault was detected on
the board). Wait several seconds to see if the green Power LED
stops blinking. If it does not stop blinking after
several seconds, enter
cfgadm
and verify that the
board is in the
unconfigured
state, then perform
the necessary action, depending on the board:
• Alarm card—You can remove the alarm card in
this state.
• All other boards—Power off the slot through the
alarm card software, then remove the board.
On On The board is powered on and is
in use, but a fault has been
detected on the board. Deactivate the board using one of the following
methods:
• Use the
cfgadm -f -c unconfigure
command
to deactivate the board. In some cases, this might
cause the system to panic, depending on the
nature of the board hardware or software.
• Halt the system and power off the slot through
the alarm card software, then remove the board.
The green Power LED gives status information:
• If the green Power LED goes off, remove the
board.
• If the green Power LED remains on, halt the
system and power off the slot through the alarm
card software.
