Installing rails
About this task
Install the rails from the front of the cabinet where you will install the shelf. The 4U rack includes inner rails that slide into the
cabinet rail assembly.
CAUTION:
Exercise care when installing the short rails. Exposed metal edges may be sharp and could damage
cabling or cause injury to personnel.
Steps
1. Locate the 4U high cabinet space designated for the shelf.
2. Adjust rail length if required.
3. The rails are shipped with M5 adapters, which fit into the Dell EMC NEMA channels. For Dell EMC racks, proceed to step 4.
For third-party racks, proceed as follows:
a. Using a flat-tipped screwdriver, remove the two M5 adapters from the adapter mounting block on the rails.
b. Select the required adapters from the hardware kit and install the adapters into the adapter mounting block. The
following table shows the pins for third-party racks.
