Installation in the Dell EMC Titan or Titan-D racks
If installing to Titan or Titan-D racks, the Stab-in/Drop-in Sliding rails (B13) must be used. This rail collapses down suciently to t in racks
with mounting anges spaced about 24 inches apart from front to back. The Stab-in/Drop-in Sliding rail allows bezels of the servers and
storage systems to be in alignment when installed in these racks.
System-to-Rail Installation Method
If the customer prefers to use the stab-in installation method for installing their systems to the rails, the Stab-in/Drop-in Sliding rails(B13)
or the ReadyRails Static rail (B4) must be selected.
NOTE
: ReadyRails Sliding rails (B6) are drop-in only.

NOTE
: No screws are required for the Stab-in/Drop-in Sliding (B13) rails when mounting the rails to the racks
NOTE: Screws are not included in either kit as threaded racks are oered with various thread designations. Users must therefore
provide their own screws when mounting the rails in threaded racks.
NOTE: Screw head diameter for the sliding rails must be 10 mm or less.
