Rack requirements
Each server ships with a sliding rail kit. The sliding rails allow you to fully extend the enclosure out of the
rack for service.
Caution:
See the Rack Installation Instructions supplied with the rail kit for safety and installation
instructions.
The racks you use for each server must meet these requirements:
• The sliding rails support tool-free mounting in 19-inch, EIA-310-E compliant square-hole, 4-post racks,
and also support tooled mounting in threaded 4-post racks.
• Each enclosure is 2U. Ensure the rack has sufficient space for all enclosures.
• For full power redundancy across all servers, you need a rack with two power distribution units (PDU)
feeding separate outlet strips, with sufficient vacant outlets on each strip.
• Ensure the rack is installed and stabilized or bayed according to the manufacturer's instructions.
WARNING:
When servicing an enclosure in a rack, extend only one enclosure at a time to prevent the
rack from tipping.
Rack installation guidelines
There are guidelines to help you successfully install each server in a rack.
• Follow all safety guidelines stated in the documentation that came with the rack, particularly when
installing components into the locations at the top of the rack.
• Ensure the rack meets the requirements.
• Install the servers in the same rack when possible.
• Install the servers in a rack starting from the bottom of the rack.
• Always install the servers in a horizontal position, or you void your warranty and support contract.
Install the server enclosure in a rack
You install the rails, which are included in the shipping carton, at the lowest available U space in the rack
enclosure. You then work up from the bottom of the rack to add additional rails.
Before you begin
