Types of Rack Rails

There are 2 different types of Rack Rails available:

Static Rails:

For mounting servers in a rack without an option to move them after installation. If another server is mounted directly above, the system has to be unmounted
for any work on the server hardware.

Sliding Rails:

For mounting servers in a rack with the option to work on the server hardware, even when another server is mounted directly above. The server can be pulled out of the rack from the front.
