Using Dell ReadyRails (Optional)
Dell Networking offers the Dell ReadyRails rack mounting system as an option to ease the installation of a
switch in a 2-post or 4-post rack. You must order a ReadyRails kit as a separate item; it is not part of the
C9010 base configuration.
You can install ReadyRails using a tool-less method in a non-threaded-hole rack or a tooled method in a
threaded-hole rack. Dell ReadyRails support a rack depth of 24 to 30 inches.
WARNING: Due to the weight of a fully populated C9010 chassis, never install or pull a full chassis
out of a rack with ReadyRails. First remove each component before you lift or remove the chassis.
The ReadyRails kit consists of:
•
Chassis rails that fit on the left and right sides of a C9010 chassis (items 1 and 2 in Figure 10)
•
Left and right rail brackets that fit into the front rails on 2-post racks (items 3 and 4 in Figure 10)
