Page 31: Figure 1-15 Cooling Module
Plug-in Modules Figure 1-15 Cooling Module In a redundant configuration, the modules operate together; if one fails, the other maintains adequate cooling to the system while the faulty unit is replaced. Caution: Do not remove a module unless a replacement can be immediately added. This is particularly important in a single-cooling module system, which will very quickly overheat unless a properly functioning cooling module is installed. -
Page 32: Dummy Carrier Modules
1: Storage System Features Dummy Carrier Modules Dummy carrier modules are provided for installation in all unused drive bays. They are designed as integral drive module front caps with handles and must be installed in all unused drive bays to maintain a balanced airflow. Caution: If any modules are missing, operation of the enclosure will disrupt the airflow and the drives will not receive sufficient cooling. -
Page 33: Storage System Bay Numbering Convention
I/O, or cooling module. The SGI TP900 system has 8 drive bays in the front of the enclosure—2 rows of 4 bays. A front bay is identified by a row/column fraction. Rows are numbered 1 to 2 from top to bottom, and columns are numbered 1 to 4 from left to right, viewed from the front. -
Page 34: Figure 1-17 Rear Module Locations And Bay Numbering
1: Storage System Features The SGI TP900 system has 6 module bays at the rear—2 rows of 3 bays. A rear bay is identified by a row/column fraction. Rows are numbered 1 to 2 from top to bottom, and columns are numbered 1 to 3 from right to left, viewed from the rear. For example, module 2/3 refers to the bay located in row 2 (bottom) and column 3 (third from the right). -
