the drive modules in the server are hot-pluggable; that is, you can remove one and replace it with another drive while the server is running. a status light on each drive indicates when it’s safe to remove a drive without losing any information.

    follow these steps to install or replace a drive module.

    1 if necessary, use the enclosure key to unlock the security lock on the server’s front panel.

    2 remove the blank drive module or the drive currently installed.

    if there is no drive installed, press the handle on the front of the blank drive module so that the handle pops out, then pull the blank drive module out of the front panel.

   

    if there is a drive module already in the bay:

    a make sure the drive currently in the bay is not being used by any application and that the drive is not being shared by the server. (see the mac os x server documentation for information about shared drives.)

    b press the handle on the front of the drive module so that the handle pops out.

   

    c wait for the upper disk light to go off, then grasp the handle and pull the drive module out of its bay and set it aside.

   

    3 press to open the handle of the replacement drive module and slide it into the empty bay until its connector clicks into place.

    4 the disk status light turns green to indicate normal operation.

    important be sure to save the blank drive module if you removed one. this module should always be placed in an empty drive bay to maintain proper airflow through the server.
