Apple Xserve (Early 2008) - Manual (Page 28)

28 Chapter 2 Installing or Replacing Components
Removing or Installing a Power Supply
You can replace or install a power supply from the back panel without removing the
Xserve from the rack. If the Xserve has two power supplies, they are hot-swappable;
the Xserve continues to operate using only one supply while the second is removed.
To remove a power supply:
1 Unclip and unplug the power cord from the power supply you are removing.
2 Pull the handle to release the power supply and slide it out of the bay.
WARNING: Install power supplies with a rating of at least 750 Watts. The power
supplies that come with previous Xserves are rated at less than 750 Watts.
WARNING: The power supplies in a running Xserve might be hot.
Pull the handle to unlatch the
power supply and remove it.
To add a second power
supply, use the notch in the
power supply bay cover to
rotate the cover outward.
Remove and save the cover.
