Installing an expansion cable management bracket (optional)
Each 12508E and 12518E switch provides two types of chassis cable management brackets. You can select either type as needed.
Cable management brackets—Shipped with the switch. For more information, see " Chassis views and technical specifications."
Expansion cable management brackets—Upper cable management bracket with a mark, and lower cable management bracket with no mark. They are installed in the same positions as the cable management brackets shipped with the switch except that they can route more cables.
To install expansion cable management brackets, remove the cable management brackets shipped with the switch first.
