Overview

At the time this document was published only the tall (42U) and short (20U) Altix racks shown in Figure 5-1 and Figure 5-2 were tested and approved for use with Altix 450 systems. Use of other racks are at the discretion of the owner and no testing of usability, serviceability or durability is implied.

Note: While the Altix 450 can be installed in a non-Altix 450 rack, it is preferable to install it in an Altix 450 tall (42U) or short (20U) rack. The mounting rails on the Altix racks are recessed to allow for flush mounting of the IRU in the rack. The Altix rack also has provisions for PDUs to be mounted in the front. Installing the Altix 450 in a third-party rack will require that the unit protrude from the front of the rack. It will not be possible to use a front door on the third-party rack due to the protrusion of the unit. Power cables for the IRU power supplies will need to be routed to the rear of the rack if the PDUs are located in the rear of the rack. Airflow in the rack must be front to rear. Other devices installed in a rack must have their airflow direction front to rear. Cables may need to be routed from the rear of the devices to the front of the Altix 450 IRU. Vertical space must be left (U space) for cable routing front to rear in the rack.
