Determine Location of Switch Ducting and Switch Support Bracket
NOTES: Front to back span of equipment rails may need to be adjusted to accomodate your switch. See table below for front to rear rail
spacing requirements. Equipment installed directly below CDE2 may impede routing of switch power cord if installed prior to CDE2.
Switch Ducting and Switch Support Bracket components of CDE2 require two (2) rack spaces for installation. Switch Ducting and Switch
Support Bracket are to be installed at the same vertical rack position. CDE2 components are to be installed prior to switch installation and
are designed to support the switch. (CDE2 ducting system ONLY
switch cradle or extension brackets are not compatible with CDE2.)
