System reliability considerations To help ensure proper cooling and system reliability, make sure: Each drive bay has either a drive or a filler panel installed. If a slim-high drive is installed, make sure that the slim filler bezel is installed. Each power supply bay has a power supply installed. The top cover is in place during normal operation. If the server is on, do not leave the top cover off for more than 30 minutes at a time. The memory-access panel is in place during normal operation. To leave sufficient space around the server to allow the server cooling system to work properly. Refer to the server rack documentation, for example, IBM Netfinity 9308 Enterprise Rack Planning Guide, for additional information. Cables for optional adapters are routed according to the instructions that come with the adapters. A fan that has failed (indicated by a lit amber LED) is replaced as soon as convenient to help maintain the redundant cooling capability. Additional processors are installed on the processor daughterboards in the correct order. See "Processor housing assembly" on page 146 for installation instructions. Additional DIMMs are installed on the memory boards in the correct order. See "DIMM and memory board installation" on page 63 for installation instructions. 162 Netfinity Server HMM
