Q-Logic MKII-BASE16 user manual Procedure, Step, Is the Logic Power Good LED lit?

Continuous Test

For example:

•If the only problem with the Switch is one or more bad GBICs, the POST tests will not detect the problem at power-up because they do not test the GBICs. The Continuous Tests, however, will detect the problem and blink a heartbeat error code of eight (8) blinks to indicate a GBIC test failure. In this case, when you return the Continuous Test button to the IN position the Switch will read its error log and blink the Logged-in LED for the failing GBICs.

If the Heartbeat LED continues to blink its normal heartbeat while the tests are running, the Switch is passing the tests.

Procedure

The following steps assume you have AC power applied to the Switch, the Power Button is in the ON (In) position, and the Continuous Test button is in the OP (In) position. Figure 1-1 shows the location of the Power Button.

Step 1

Note the state of the Logic Power Good LED. Figure 1-1 shows the location of the Power Good LED.

Is the Logic Power Good LED lit?

Yes Go to Step 2.

No Go to the Power Supply/Fans Troubleshooting procedure to determine what is causing the problem; then correct the problem. Return to Step 2 of this procedure only when the Power Good LED is lit.

Step 2

Install a Loopback Plug on each of the installed GBICs. Your Switch was shipped with a Loopback Plug for each GBIC.

If the Switch was previously cabled, tag and remove all cables and install a Loopback Plug on each GBIC.

Step 3

Set the Continuous Test button to the TST (Out) position. Figure 3-2 shows its location.

Step 4

Note the state of the Heartbeat LED. Figure 1-1 shows the location of the Heartbeat LED. As long as the Heartbeat LED is blinking the normal heartbeat (one blink per second) the Switch is passing the Continuous Tests. Let the tests run for about a minute, then:

a.If the Heartbeat LED is blinking its normal heartbeat (not an error code), press the Continuous Test button to place the Switch back in its normal operate mode (OP) and go to Step 5.
