This test initializes the ethernet controller’s serial EEPROM if the current contents are invalid. In any case, this test
will also allow the user to enter a six byte ethernet MAC address into the serial EEPROM.
Enter the menu item number (0 to quit): 6
Current MAC address: 00:80:4d:46:00:02
Enter desired MAC address: 00:80:4d:46:00:01

Battery Status Test
This tests the current status of the battery. First, the test checks to see if the battery is installed and reports that
finding. If the battery is installed, the test further determines whether the battery status is one or more of the
following:
• Battery is charging.
• Battery is fully discharged.
• Battery voltage measures within normal operating range.
Battery Backup SDRAM Memory Test
This tests the battery backup of SDRAM memory. This test is a three step process:
1. Select Battery backup test from main diag menu, then write data to SDRAM.
2. Turn off power for 60 seconds, then repower the board.
3. Select Battery backup test from main diag menu, then check data that was written in step 1.
Timer Test
