Removing an E-DDM
Complete the following steps to remove a hot-swap E-DDM:
Note:
The E-DDM comes installed in a drive tray. Do not attempt to detach the
E-DDM from the tray.
1. Use Table 55 on page 194 to record the location and identify your E-DDMs. You
must record this information to be able to replace the E-DDMs in their original
order before they were removed.
2. Release the latch on the E-DDM CRU by pressing on the inside of the bottom
of the tray handle.
3. Lift the closed latch to its open position. (The latch is at a 90° angle to the front
of the E-DDM when open.)
4. Pull the E-DDM out of the bay, as shown in Figure 24 on page 46.
