Attaching the Device to a Four-Post Rack

A four-post rack-mounting kit (XN-4P-RKMT301 for SLX9740-80C or XN-4P-RKMT302 for SLX9740-40C) is included in the box with your switch router. The kit contains an instruction sheet, along with the following components:
  • Two slider assemblies including inner rail (member) or intermediate rail (member), and outer rail (member).
  • Two front mounting ears with black thumb screws in the middle (for SLX9740-40C), or a black thumb screw and handle (for SLX9740-80C). These pieces attach directly to both sides of the device housing.
  • Mounting ears - Black rack ears with a thumb screw in the middle (2 count).
  • Black mounting ear screws (6 count for front two rack ears of SLX9740-40C and 12 count for front two rack ears of SLX9740-80C).
  • Grounding screws - M4 screws to install the lug cables (not provided) to the rack on SLX9740-40c (4 count).
  • Rail screws - M4 screws to secure the inner rail to the device (2 count).
