Introduction
This 3.5” trayless SATA Mobile Rack allows you to install two 2.5”
SATA drives in an available/unused 3.5” floppy drive bay. Featuring a
convenient trayless “easy eject” feature (like a tape cartridge or floppy
disk), the hard drive bay doesn’t require that the drives be installed into
a tray - making it the ideal solution for quick and easy drive removals
and insertions as part of a system building process, or integration into
rackmount systems or industrial environments.

Installation
WARNING: Hard drives require careful handling, especially when
being transported. If you are not careful with your hard disk, lost data
may result. Always handle your hard drive and storage device with
caution.
Hardware Installation
Make sure the computer system is powered off and unplugged from 1.
the power source before attempting any hardware installation.
Locate an available external 3.5” floppy drive bay on the 2.
computer case and install the Mobile Rack appropriately. See
the documentation for your computer case for installation details.
Mounting screws are included, if necessary.
Connect two 7-pin SATA cable from the back of the Mobile Rack to 3.
the SATA port in the computer system.
Connect the 15-pin SATA power cable from the computer power 4.
supply to the Mobile Rack.
Pull on the metal tabs/hinge on the front of the Mobile Rack to open 5.
the drive bay doors. Insert a SATA hard drive into the drive bay
(label facing up) and close the door behind it, making sure it latches
properly.
OPTIONAL: Use the included keys to lock the front door to prevent
accidental/unauthorized access to the hard drive(s).
Power up the computer and use the hard drive(s) as if connected 6.
directly to the SATA controller/motherboard.
Driver Installation
No driver installation is required for any operating system, as this
Mobile Rack is a pass through device, so only the hard drives are seen
by the computer system.

How to Use
If the SATA controller supports Hot-Swapping drives, then hard drives
can be removed and installed into the Mobile Rack without having to
shut the computer system off. Refer to the documentation for the SATA
controller for details on how to use Hot-Swapping. If not supported, the
computer must be shut down first, to install or remove hard drives.
To remove hard drives from the Mobile Rack, unlock the front drive bay
door (if necessary) with the provided keys and open the door by pulling
on the metal latch. Swing the door fully open and the drive will be
ejected, and can then be pulled out of the drive bay by hand.
