Running a Power On Self Test (POST)

Note: Not supported on LPe15000 or LPe16000 series adapters.

The POST is a firmware test normally performed on an adapter after a reset or restart.

The POST does not require any configuration to run. (Not available in read-only mode.)
To run the POST:
1. From the discovery-tree, select the adapter port on which you want to run the

POST.

2. Select the Diagnostics tab and click Power-on Self Test (POST). A warning dialog

box appears.

3. Click OK. A POST window appears displaying POST information.

Note: After the test starts, it cannot be cancelled. It must run to completion.

Using Beaconing

The beaconing capability enables you to force a specific adapter’s LEDs to blink in a

particular sequence. The blinking pattern acts as a beacon, making it easier to locate a

specific adapter among racks of other adapters. (Not available in read-only mode.)
When you enable beaconing, the two LEDs blink rapidly in unison for 24 seconds, after

which the LEDs report the adapter health status for 8 seconds. When the 8 seconds are

up, the adapter returns to beaconing mode. This cycle repeats indefinitely until you

disable beaconing or you reset the adapter.

Note: The beaconing buttons are disabled if the selected adapter does not support

beaconing.

To enable or disable beaconing:
1. From the discovery-tree, select the adapter port whose LEDs you want to set.
2. Select the Diagnostics tab and click Beacon On or Beacon Off.

Running D_Port Tests

D_Port is a diagnostic mode supported by Brocade switches for 16Gb FC. D_Port tests

enable you to detect physical cabling issues that result in increased error rates and

intermittent behavior. When activated, D_Port runs a series of tests including local

electrical loopback, loopback to the remote optics, loopback from the remote port to the

local optics, and a full device loopback test with data integrity checks. It also provides

an estimate of cable length to validate that a proper buffering scheme is in place. The

various loopback tests allow some level of fault isolation so you can distinguish faults

due to marginal cable, optics modules, and connector or optics seating.

Note:

Basic connectivity diagnostics are already supported by Emulex HBAs. The

OneCommand Manager application has diagnostic modes that support

validation of connection to the switch. The functionality that Brocade offers
