Appendix Server Diagnostics Test Reference 53

Even though these tests don’t test all memory, run these tests to detect intermittent

memory issues.

After the rst 2.5 GB of memory is tested, the memory test then tests for ECC errors.

When an ECC error occurs, memory catches the problem and xes it. The test detects

the number of memory xes and reports them.

Note: The time required to complete memory tests correlates to the size of memory

being tested. These estimates are based on testing 1 GB of memory.

Test Estimated completion time Description

Simple Test 17 minutes Runs all multicore memory

tests listed in Server Diagnostics

EFI, reports the number of

ECC errors, and then resets the

count.

Power Supply Tests

Test Estimated completion time Description

Good 1 second Checks if the power supply’s

good bit is set. If it’s not set, this

could indicate that the power

supply isn’t seated well or is bad,

or that there’s no AC connected.

Quick 5 seconds This is available only if you have

more than one power supply.

This turns o the redundant

power supplies so that only one

is run on.

Sensor Tests

When Server Diagnostics Mac OS X starts, it performs a hardware existence test. All

sensors found during this test can be tested individually using sensor tests.

Test Estimated completion time Description

Sensor Reads 1 second Veries that the sensor reads are

within the preset sensor limits.

USB Tests

Connect USB devices before running USB tests.

Test Estimated completion time Description

Presence 1 second Veries that a USB device is
