Appendix AXD Tools Test Reference 35

AXD Mac OS X Tests

These tests are available if your Xserve is running AXD Mac OS X tools.

Ethernet Controller Tests

Data loop tests can add to network traffic. Consider disconnecting from the network

before running the data loop tests.

Hard Drive Tests

Memory (Simple) Tests

Simple memory tests test the first 2.5 GB of memory. All multicore memory tests listed

in AXD EFI tools are run.

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

intermittent memory issues.

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

MAC Address Verification 1 second Verifies MAC address is not all FFs or

00s

Ethernet ROM Checksum 1 second Verifies Ethernet ROM checksum is

valid

MAC Data Loop 1 minute Verifies that there’s no data mismatch

between sent and received data while

looping within the MAC (a sublayer of

the datalink layer in the ISO network

reference model)

PHY Data Loop 1 minute Verifies that there’s no data mismatch

between sent and received data while

looping within the physical transport

medium (PHY)

Test Estimated completion time Description

Threaded Surface Scan 30 minutes for an 80 GB

drive; 4 hours for a 750 GB
