Tape backup unit (optional)
A tape backup unit (TBU) is a data storage device that reads and writes data on a magnetic tape. A TBU has the ability to periodically copy the contents of all or a designated amount of data from its usual storage device to a tape cartridge device so that,  in the event that the source get irreparable damaged, the data will not be lost.
The tape backup unit is supported only on 2.5-inch hard drive systems.
Removing the tape backup unit 
Prerequisites
1.Follow the safety guidelines listed in safety instructions section.
2.Follow the procedure listed in the Before working inside your system section.
CAUTION: Many repairs may only be done by a  certified service technician. You should only perform troubleshooting and 
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support  team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.
Steps
1.Disconnect the power and data cables from the back of the tape backup unit.
167 
						

							Ensure you note the routing of the power and data cables inside the chassis as you remove them from the system board and the tape backup unit. You must route these cables properly when you replace them to prevent them from being pinched or crimped.
2.To remove the tape backup unit, press the release tab and slide the tape backup unit out of the tape backup unit slot.
NOTE: If the tape backup unit is being permanently removed, install a tape backup unit blank by sliding it into the 
slot until it snaps into place.
NOTE: The procedure to install and remove the tape backup unit blank is similar to that of the tape backup unit.
NOTE: Tape backup unit blank must be installed in empty tape backup unit slot to maintain FCC  certification of the 
system. The blank also keeps dust and dirt out of the system and aid in proper cooling and  airflow inside the system.
