Xserve (Late 2006) Logic Board Replacement Instructions
Changing the Ethernet ID Label
Replacing the logic board in the Xserve changes its Ethernet ID numbers (MAC addresses)
for both Ethernet ports. The new numbers are printed on Ethernet labels packaged with the
replacement logic board. After installing the new logic board, place the new Ethernet labels
over the original Ethernet numbers on the Xserve’s ID tab. Be careful to apply the new stickers
completely onto the ID tab, smoothing out the labels so that they are completely flush with the
tab. Do not leave any part of the labels (such as the corners) sticking up or these might catch and
tear in the ID tab’s opening in the rear panel when the tab is reinserted into the enclosure.
Closing the Xserve
Replace and secure the cover.
Slide the Xserve back into the rack, and tighten the front thumbscrews to secure the Xserve
in the rack.
If the server case was locked, use the enclosure key to lock the security lock on the front
panel.
