Understanding LED Status Indicators

Language:

The Port 1 and Port 2 LED status indications vary depending on the operating protocol mode of the universal HBA (see Determining and Changing the Current Operating Protocol Mode):

Figure 7, Table 7, Universal Host Bus Adapter Port LEDs for CNA Mode summarizes the LED status indications for CNA mode. The Mode, Activity, and Link LED columns correspond to the LEDs in Figure 2–4 from left to right.
Figure 8, Table 8, Universal Host Bus Adapter Port LEDs for FC Only Mode summarizes the LED status indications for Fibre Channel (FC) Only mode. The 16 Gb, 8 Gb, and 4 Gb columns correspond to the LEDs in Figure 2–4 from left to right.

In addition, the OK/Power and Service Required LEDs indicate the following:

The OK/Power LED is static green when the hardware is powered on and operating normally, and off when the hardware is powered off.
The Service Required LED is static green when the hardware is powered on and operating normally, flashing green when the –ATTN button is pressed (see To Prepare the Universal HBA for Removal Using the Attention Button), and off when the hardware is powered off.
