4. Once the rails are adjusted to the proper length, install the rails in the rack.
Installing the rails in a non-EMC rack
Exercise care when installing the short rails. Exposed metal edges may be sharp
and could damage cabling or cause injury to personnel.
For each shelf, install the rails using the table, figure and steps that follow. The rails
are designed to be universal in nature. They are shipped with 6.8mm adaptors that will
fit into any EMC rack. To install the universal rails into a non-EMC rack, the 6.8mm
adaptors must be removed, then replaced with rail pins that will fit the hole-types in
the rack being used. The following table shows the rail pins and their suggested use .
