Third-party rack installation

Follow these best practice guidelines to ensure an orderly installation:

  • Third-party racks might have PDUs which face into the rack. This can cause interference between the shelf and/or rear CMAs. Carefully plan and route cables to minimize any interference. It might be necessary to use a type of PDU that is mounted in the main rack area.
  • The shelf rails have four adjustment ranges, 18-22", 22-26", 26-30", 30-34". The default length (out of the shipping crate) is the 22-26" setting.
  • After installation, check each rail to ensure that it is level and in the correct location before installing the next rail.
  • When securing rails to the NEMA channel, especially channels with square holes, install the screws loosely to prevent cross threading, and tighten by hand. Do not over torque.
  • Use black M5 screws, which align with both round and square channel holes, to secure all rails and components in the customer racks. Discard all silver screws removed from the shipping rack.
