Using Dell ReadyRails (Optional)
Dell Networking oers 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 conguration.
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 t on the left and right sides of a C9010 chassis (items 1 and 2 in Figure 10)
• Left and right rail brackets that t into the front rails on 2-post racks (items 3 and 4 in Figure 10)
• Front rails for the left and right posts of 2- and 4-post racks (items 5 and 6 in Figure 10)
• Rear rails that t into the left and right front rails on 4-post racks (items 7 and 8 in Figure 10)
• Two spacers that allow you to secure the chassis anges ush on the front rack posts (items 9 and 10 in Figure 10)
