States
Blade Model Possible Green LED States and Explanations
6404 • Solid on — the I/O blade has established a proper link and is ready to use. The
drive detects light through the fiber optic cable.
• Blinks slowly — the link is up and currently transporting commands.
• Blinks rapidly — when the I/O blade is beginning to reboot or power up, all I/O
blade link LEDs, along with the I/O blade’s green status LED, blink rapidly to
indicate that the blade is starting the Power On Self Test (POST).
• Blinks with other link LEDs in a racetrack pattern — when all of the I/O blade
link LEDs blink consecutively in a clockwise order, the blade is booting up. This
pattern stops when the blade is powered and ready. If the pattern doesn’t stop,
the blade is unable to completely boot up. In this situation, follow the repair page
instructions.
• Solid off — the I/O blade does not detect light through the fiber optic cable.
7404 • Solid on — the I/O blade has established a link but is not currently transporting
data.
• Blinks — the link is active and is currently transporting data.
• Solid off — the I/O blade has not established a link OR the link is active and is
currently transporting a large amount of data.
Note
For the 7404 I/O blade, fibre port LEDs are off
while the blade is booting up.
