Viewing LEDs

Language:

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:

LED Indicator Combinations

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.

Table 6 FC Mode LED Status

Green LED	Yellow LED	State
Off	Off	Boot failure (Dead board)
Off	On	POST failure (Dead board)
Off	Slow Blink	Boot failure after POST
Off	Fast Blink	Not Defined
Off	Flashing	POST processing in progress
On	Off	Failure in Common Code Module
On	On	Failure in Common Code Module
On	1 Fast Blink	Normal (Link up at 2 GFC) (legacy compatibility only)
On	2 Fast Blinks	Normal (Link up at 4 GFC)
On	3 Fast Blinks	Normal (Link up at 8 GFC)
On	4 Fast Blinks	Normal (Link up at 16 GFC)
On	Flashing	Not defined
Slow Blink	Off	Normal link down
Slow Blink	On	Not defined
Slow Blink	Slow Blink	Not defined
Slow Blink	Fast Blink	Not defined
Slow Blink	Flashing	Not defined
Fast Blink	Off	Not defined
Fast Blink	On	Not defined
Fast Blink	Slow Blink	Not defined
Fast Blink	Fast Blink	Beaconing
Fast Blink	Flashing	Not defined

Note - For the link rate conditions, there is a 1 second pause when the LED is off between each group of fast blinks (2, 3, or 4). Observe the LED sequence for several seconds to be sure you have correctly identified the pattern.

POST Results

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
