General Information Overview Xserve G5 is a server designed to mount into a rack; Apple recommends that you remove the Xserve G5 server from the rack before replacing or installing all parts except hard drives. You can replace hard drives while the server is operating and still in the rack. To identify versions of the Xserve G5, check the front panel. Xserve G5 and Xserve G5 (January 2005) include a slot-load optical drive and three hard drives.
Important: There are two versions of the Xserve G5 logic board that must be replaced like-for-like. Identify version 2 logic boards by the “DDR 2GB” (Double-Data-Rate, 2 gigabyte memory) label as shown below. Mounting in a Rack For information on mounting Xserve G5 in a rack, see the Xserve G5 User’s Guide. Tools You will need a medium and a small Phillips screwdriver and a small flat-blade screwdriver for some procedures. If the server is locked, you will also need the server’s Allen wrench key.
Before Opening the Server Serial Number Be sure to write down the server’s serial number. If the server’s software must be set up after service is complete, the serial number will be required for login. Unlocking the Server If the server is in the locked position (the yellow security LED on the front panel is on), use the Allen key that came with the server to unlock it.
Hard Drive Xserve G5 and Xserve G5 (January 2005) include three hard drive bays at the front of the server; Xserve G5 (Cluster Node) includes just one drive bay. Drives come as modules attached to carriers; they are removed from or installed in the server as a unit. Note: Blank drive carriers, which may fill some of the hard drive bays, follow the same take-apart procedure as hard drives.
Procedure 1. Make sure the drive being replaced is not in use by any application and is not being shared by the server. (See the Mac OS X Server documentation for information about shared drives.) 2. Unmount the drive (by using the command-line tools or by dragging the disk icon to the Trash). 3. Press the handle on the front of the drive module so that the handle pops out. 4. Wait for the upper LED on the drive to go out. Then grasp the drive handle, and pull the drive module out of the server.
Opening the Server The server slides open from the front of the rack. The server’s top cover remains in place in the rack; the bottom housing (containing all internal components) should be placed on a sturdy, flat surface. Tools No tools are required for this procedure. You may, however, find a Phillips screwdriver useful in releasing the thumbscrews in step 1 below. Preliminary Steps Before you begin this procedure, write down the server’s serial number located on the back panel.
Procedure 1. Release the two thumbscrews at the front of the server. Note: The thumbscrews are captive and do not separate from the bottom housing. 2. Grasp the thumbscrews and slide the bottom housing forward part way to expose the two chassis levers. 3. While depressing both levers, pull the bottom housing all the way forward and remove it from the rack. Place the bottom housing on a sturdy, flat surface and ESD mat.
DIMMs Xserve G5 has eight Dual Inline Memory Module (DIMM) slots arranged in two banks. The slots accept Double-Data-Rate (DDR) Synchronous Dynamic Random-Access Memory (SDRAM) devices. Depending on your configuration, the computers ship with a pair of DIMMs installed in slot 1 of each DIMM bank. You can add DIMMs, provided they are installed in pairs of equal size, one per bank, from the center outward. Numbers marked on the logic board next to the DIMM slots illustrate how the pairs must be installed.
Important: Always install DIMMs in pairs of equal size. Memory from older Macintosh computers is not compatible with Xserve G5. Do not use older memory, even if it fits into the DIMM slots. Caution: Do not install 2 GB DIMMs in Xserve G5 main logic boards that did not previously have 2 GB DIMMs installed. Only Xserve G5 main logic boards labelled “DDR 2GB” accept 2 GB DIMMs. Refer to the Logic Board procedure for more information. Tools No tools are required for this procedure.
Procedure 1. Push down the ejectors on the DIMM slot. 2. Holding the DIMM by both top corners, lift it straight up out of the server. Warning: When removing or installing the DIMM, handle it only by the edges. Do not touch its connectors. Lift the DIMM straight up from the connector to remove it, and insert it straight down into the connector to install it. Do not rock the DIMM from side to side. Replacement Note: The DIMM is designed to fit into the slot only one way.
