Appendix D. Specifications - pre-August, 2009 racks

This appendix explains those specifications that are relevant to racks ordered with
feature code 1100 (interface module). Racks ordered August, 2009 or later use
feature code 1101 (dual CPU interface module), which supersedes feature code
1100. In this appendix, racks ordered with feature code 1100 are referred to as
"pre-August, 2009 racks."
The appendix describes specifications that are different in racks ordered with
feature code 1100 and racks ordered with feature code 1101. Common features
between the two types of racks are described in the main chapters of this
document.

Power consumption - pre-August, 2009 racks

Table 20 provides a complete power consumption listing for supported rack
configurations.

Notes:

1. Seven (7) and eight (8) module configurations are not supported.

2. Power consumption for partial rack configurations are typical values and are provided
for reference purposes only. To support concurrent capacity upgrades, the installation
site must provide sufficient power capacity to support a full rack configuration.
