CISCO CWDM-CHASSIS-2 No Modules 2-slot CWDM chassis CWDM-CHASSIS-2
The CWDM system shelf (CWDM-CHASSIS-2) is a standard 19-inch chassis that is one rack unit (RU) in height. Install the CWDM system shelf in the same equipment rack as your switch or in an adjacent rack so that you can connect the CWDM plug-in modules to the CWDM GBICs in your switch.
The CWDM system shelf has two slots. You install CWDM OADM modules or Mux/Demux plug-in modules in the slots.
