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. Front to rear rail spacing
requirements range from 24.0" TO 30.5". Equipment installed directly below CDE3 may impede routing of switch power cord if installed
prior to CDE3.
Switch Ducting and Switch Support Bracket components of CDE3 require (4) rack spaces for installation. Switch Ducting and Switch Support Bracket are to be installed at the same vertical rack position. CDE3 components are to be installed prior to switch installation and are
designed to support the switch. (CDE3 ducting system
cradle or extension brackets are not compatible with CDE3.)
ONLY requires use of primary Cisco rack mount brackets. Cisco supplied switch
