Installation Strategy

The following general information and strategy applies to both the 1.6-meter and 2.0 meter racks. To
determine detailed components required for installation, refer to the "Installation Procedures" section later
in this appendix.
1. Upgrade the rack's power
The HP A4915A SureStore E Disk Array 12H Power Upgrade kit is supported only for 240 VAC
power systems. This upgrade provides three 10-receptacle 240 VAC PDUs. PDUs for non-US
installations must be ordered with the appropriate plugs, refer to the Table 20 below.

2. Upgrade the rack's cooling capacity
Back-to-Back racking requires that the cooling capacity of the rack be upgraded. The cooling upgrade
requires installation of a new Exhaust Fan Assembly (product E7687A). This assembly contains three
fans, an LED fault indication circuit and a 1- EIA unit air scoop. This is required to promote maximum
airflow through the center of the rack. Also, to promote additional air flow, the rear cabinet door will
be removed and set aside.
To maintain cooling efficiency, filler panels should be installed in any unfilled spaces in the front and
back of the rack (see Table 19).
