To place the system in a proper location, it is necessary to know the dimensions of the device's chassis.
The Cisco 5100 ENCS can be placed on a desktop or installed in a rack. The mounting ears for the device are
designed for #12-24 UNC screws.
The location of your device and the layout of your equipment rack or wiring room are extremely important
considerations for proper operation. Equipment placed too close together, inadequate ventilation, and
inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for
access to both front and rear panels of the device.
This information can help you plan the rack configuration for your equipment:
• Allow clearance around the rack for maintenance.
• Allow at least one rack unit of vertical space between devices.
