18 Sun StorageTek Enterprise PCI-X 4 Gb FC Single & Dual Port Emulex HBAInstallation & Interop Guide • January 2007
▼ To Apply Power
1. Verify that the HBA is securely installed in the system.
2. Verify that the correct optical cable is attached.
3. Plug in and power on the system.
4. Observe the status of light-emitting diodes (LEDs) for the power-on self-test
(POST) results as shown in
TABLE 3-2.
TABLE 3-2 summarizes LED indicator combinations. The LEDs can be seen
through the openings in the HBA’s mounting bracket. Each port has a
corresponding set of LEDs that provide a visual indication of the operating state.
The slow blink rate is 1 Hz; the fast blink rate is 4 Hz; the flashing state is an
irregular on/off appearance reflecting program activity. For the Link Rate,
between each group of fast blinks (1, 2, or 3), there is a 1-Hz pause when the LED
is off. You should observe the LED sequence for several seconds to ensure that
the pause is correctly identified.
