WARNING!
Forcing or slamming a module into place can damage the connector pins on the
module itself or that on the subsystem backplane.
Step 2. Install the new cooling fan module: Line the new module up with
the slot into which it will be inserted and then gently push it into the
chassis. The latches will hold the module in place.
5.7 Drive Tray Maintenance
5.7.1 Notes on Hard Drive Maintenance

Hot-swappable drive trays: The drive trays are all hot-swappable. If a hard drive fails, it
can be replaced while the subsystem is still running.
 Forearm handles: If the hard drive is behind either the left or right forearm handle, make
sure that the locking mechanism on the side of the handle is first released prior to
opening the handle itself. (See Figure 5- 11) The locking mechanism must also be
released in order to close the handle. Therefore, after the new drive has been installed, it
will be necessary to release the locking mechanism on the handle prior to closing it. For
more information, please refer to Section 1.5 in Chapter 1.
