Diagnostic Features Power-on self-test By default, when you power on the system, the boot loader automatically performs power-on self-tests and loads a Fabric OS kernel image. Likewise, if you issue the slotPowerOn command, or insert a new blade, a power-on self test is run on that blade. The POST tests provide a quick indication of hardware readiness when hardware is powered up. These tests do not require user input to function. They typically operate within several minutes, and support minimal validation because of the restriction on test duration. Their purpose is to give a basic health check before a new switch joins a fabric. These tests are divided into two groups: POST1 and POST2. POST1 validates the hardware interconnect of the device, and POST2 validates the ability of the device to pass data frames between the ports. The specific set of diagnostic and test commands run during POST depends on the switch model. NOTE When POST2 is running portloopbacktest mode 8 and if the peer blades are powered off while the test is running, the POST is expected to fail in the core blades as the mode 8 tests the peer links and the peer end is no longer active. NOTE Generation 5 16-Gbps switches and chassis can take several minutes to complete the POST after it is powered on. You can use the diagDisablePost command to disable both POST1 and POST2, and you can re-enable POST1 and POST2 using the diagEnablePost command. The following example shows a typical boot sequence, including POST messages: The system is coming up, please wait... Read board ID of 0x80 from addr 0x23 Read extended model ID of 0x16 from addr 0x22 Matched board/model ID to platform index 4 PCI Bus scan at bus 0 Checking system RAM - press any key to stop test Checking memory address: 00100000 System RAM test using Default POST RAM Test succeeded.

Power-on self-test
By default, when you power on the system, the boot loader automatically performs power-on self-tests and loads a Fabric OS kernel
image. Likewise, if you issue the
slotPowerOn
command, or insert a new blade, a power-on self test is run on that blade.
The POST tests provide a quick indication of hardware readiness when hardware is powered up. These tests do not require user input to
function. They typically operate within several minutes, and support minimal validation because of the restriction on test duration. Their
purpose is to give a basic health check before a new switch joins a fabric.
These tests are divided into two groups: POST1 and POST2. POST1 validates the hardware interconnect of the device, and POST2
validates the ability of the device to pass data frames between the ports. The specific set of diagnostic and test commands run during
POST depends on the switch model.
NOTE
When POST2 is running portloopbacktest mode 8 and if the peer blades are powered off while the test is running, the POST is
expected to fail in the core blades as the mode 8 tests the peer links and the peer end is no longer active.
NOTE
Generation 5 16-Gbps switches and chassis can take several minutes to complete the POST after it is powered on.
You can use the
diagDisablePost
command to disable both POST1 and POST2, and you can re-enable POST1 and POST2 using the
diagEnablePost
command.
The following example shows a typical boot sequence, including POST messages:
The system is coming up, please wait...
