358 Interpreting LED Codes
Figure 44 Locations and Colors of I/O Blade Fibre Port Link LEDs
Table 23 describes how to interpret the link LED activity that you might see. There are two different models
of I/O blade: 6404 and 7404. LED behavior varies based on which model is installed in the library.
Table 23 Explanations of I/O Blade Link LED 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
blade FC port 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.
