You can view green and yellow LEDs through openings in the mounting bracket of the HBA. Each port has a corresponding set of green and yellow LEDs. See Optical HBA LED Indicators. The green LED indicates firmware operation and the yellow LED indicates port activity or link speed.
This section describes how to interpret LED indicator combinations and power-on self test (POST) results. The section contains the following topics:
Optical HBA LED Indicators shows the LED indicators on the HBA.
Figure 1 Optical HBA LED Indicators
Each port has a corresponding set of LEDs that provide a visual indication of the operating state.
Figure 6, Table 6, FC Mode LED Status summarizes the LED indicator combinations, and their meanings, for the HBA. Refer to Optical HBA LED Indicators to determine the location of the LEDs.

Power-On Self Test ( POST) is the default mode of self-test for the Sun Storage 16 Gb FC PCIe HBA. No jumpers or connectors are necessary for this test to run. These tests perform a quick confidence level check of the HBA before running the operational software.
At a minimum, the following tests are performed by POST:
Flash boot image checksum test
Internal ASIC RAM tests for proper ECC and parity operation
NL Port loopback test
