2 Replacing Dell Storage MD1280 components This section describes the tasks to replace field replaceable units (FRUs) inside the Dell Storage MD1280 enclosure. Here, it is assumed that the user has already received the appropriate replacement device and is ready to install the device in the enclosure.
CAUTION: If the enclosure system operates for too long (depending on altitude) with drive drawers open, the enclosure can overheat, causing power failure and data loss. Such use may invalidate the warranty. Electrostatic discharge precautions To avoid injury and damage to the enclosure, always follow electrostatic discharge (ESD) precautions.
Steps 1. Turn off the PSU switch. 2. Remove the power cord from the securing clip and then remove the power cord from the PSU. 3. Push the red release tab to right and hold it, and then slide the PSU out of the chassis by using the PSU handle. CAUTION: The PSUs are heavy.
Figure 8. Securing the power cord 1. Power cable securing clip 7. Turn on the PSU switch. NOTE: Allow the enclosure to identify the PSU and determine its status. If the PSU is functioning properly, the PSU’s Power OK LED glows green and the PSU fault LED and AC fault LED are off.
CAUTION: The fan modules are heavy. To avoid injury, use both hands while removing the module. Figure 9. Removing a fan module 1. Fan module 2. Release tab 2. Rotate the replacement fan module so that the release tab and handle are on the right side. 3.

Identifying the failed EMM To identify the failed EMM, use the secli component of the Storage Enclosure Management Software or visually verify the EMM that is not functioning. For more information on using the secli to identify failed devices, see the Dell Storage MD1280 Administrator's Guide .
Replacing chassis Replacing the chassis is required when non-FRU devices must be replaced. Replacing a chassis requires a scheduled maintenance window when the system is unavailable. The replacement chassis comes without any FRUs, and therefore all cards and DDICs must be transferred to the new chassis.
b. Remove the HDBs from the rear of the rack. 3. Remove the enclosure from the rack rails. WARNING: Do not attempt to lift the enclosure without any assistance. If installed above the lower 20U of a rack, a customer ‐ provided mechanical lift must be used to avoid injury.
