POWER7 information

Planning for 6954 and 6953 racks

Hardware specifications provide detailed information for your rack. This includes dimensions, electrical, power, temperature, environment, and service clearances.

The 6954 base rack is an optional second-base frame with a separate connection to AC power that is designed for use with model 9119-FHB. A complete set of planning information is provided to address the resulting system.

Table 1. 6954 base rack components
Feature code Description
6868 Slimline doors for expansion rack
6888 Acoustic doors for expansion rack
6878 Acoustic doors for bolt on expansion rack
6880 Slimline doors for bolt on expansion rack
Notes:
  1. A Hardware Management Console (HMC) can connect to multiple systems (therefore, a Hardware Management Console might not need to be ordered), or up to two HMCs can connect to the system for redundancy.
  2. A maximum of 32 I/O drawers can be connected to the 9119-FHB rack using two FC 6954 and 6953. Typically, I/O drawers are populated in the server frame first.
