3-24 Disassembly and Reassembly
3 1/2-Inch Accessible Devices
The 3 1/2-inch accessible devices in the system are housed in a two-device bracket. The bracket
installs in the lowest bay of the accessible device cage, much like a 5 1/4-inch accessible device.
This applies equally to the desktop or minitower configuration.
The following sections describe how to remove and install 3 1/2-inch accessible devices in the
system.

Removing a 3 1/2-Inch Accessible Device

To remove a 3 1/2-inch accessible device, first remove the bracket holding the device from the
system, then remove the 3 1/2-inch accessible device from the bracket.
1. Remove the system unit cover and front panel (see “Removing the Cover” and “Removing
the Front Panel”).
Before removing the cover, turn off system power and unplug the
system power cable. Power is removed only when the power cable is unplugged.
2. Tag and unplug the power and signal cables connected to all devices in the two-device
bracket.
3. Press the tabs on either side of the bracket inward to unlatch it from the chassis.
4. Pull the bracket out the front of the chassis.

aside.
6. Remove the four screws (two to a side) that secure the device to the bracket (see the
following figure).
