Installing the rail kit
The supplied rail kits allow you to install the HP StoreOnce Backup system into square and round
hole racks for 1U and 2U servers. If mounting the HP StoreOnce Backup system into threaded hole
or telco racks, please refer to http://www.racksolutions.com to purchase the required mounting
hardware.
This installation is to be performed by qualified individuals who have knowledge of the procedures,
precautions, and hazards associated with equipment containing hazardous electrical circuits.
WARNING! These rails, when installed, form only a shelf for the server to rest on. The server is
not attached to the rail by any other means. Use extreme caution when pulling the server out from
the rack; it can slip and fall, causing damage to the server or injury. HP is not responsible for any
damage or injury caused by the mishandling of the server.
WARNING! Ensure that the rack is level and stable before working on the rack. Be sure the
leveling jacks (feet) extend to the floor and that the full weight of the rack rests firmly on the floor.
WARNING! Ensure that the rack has anti-tip measures in place. Such measures may include
floor-bolting, anti-tip feet, ballast, or a combination of these as specified by the rack manufacturer
and applicable codes.
WARNING! Ensure that sufficient personnel are on hand to support the product(s) during the
installation process. Use of the appropriate lifting device is recommended as an installation aid.
WARNING! Always load the rack from the bottom up. Load the heaviest items in the rack first.
This makes the rack bottom-heavy and helps prevent it from becoming unstable.
WARNING! Do not overload the branch circuit that provides power to the rack. The total rack
load should not exceed 80 percent of the branch circuit rating.
Mounting the HP StoreOnce Backup system
WARNING! Ensure that sufficient personnel are on hand to support the product(s) during the
installation process. Use of the appropriate lifting device is recommended as an installation aid.
NOTE: The HP StoreOnce 4700 Backup system consists of two units: a head server unit and a
storage enclosure. Make sure there is sufficient space to install both units adjacent to each other.
For both the HP StoreOnce 4700 and 4500 Backup system, plan ahead to ensure there is sufficient
space to add expansion enclosures at a later date.
1. Install the rails in the rack, as required. Follow the instructions provided separately with the
rail kits.
