5 1/4-Inch Accessible Devices
The chassis is designed so devices within it are easy to install and remove. Note these guidelines
before installing or removing a 5 1/4-inch device.
! Special rails are used on 5 1/4-inch devices that allow them to be easily inserted and
removed.
!
The rails are designed to be stored in an empty bay when they are not attached to a device.
The bay cover cannot be secured over an empty bay if the bay has no rails.
! Always place a bay cover over an empty bay.
! NECC recommends that you always keep the rails if you remove a device from the system.
!
Use your stored rails on a new device if it doesn’t have the correct type of rail.
!
When you convert the chassis to a desktop or a minitower, always move the stored rails for
the new position as well.
For procedures on removing or replacing rails, covers, or devices, see the following sections:
! “Removing or Replacing a Bay Cover”
!
“Storing and Retrieving Unused Rails”
!
“Removing or Installing Device Rails”
