Installing a hot-swap fan
The following procedure is for a Tier 1 customer replaceable unit (CRU).
Replacement of Tier 1 CRUs is your responsibility. If IBM installs a Tier 1 CRU at
your request, you will be charged for the installation. Service agreements can be
purchased so that you can ask IBM to replace these units.
About this task
For proper cooling, the file module requires that all three dual-motor hot-swap
fans be installed at all times.
Attention: To ensure proper file module operation, if a dual-motor hot-swap fan
fails, replace it immediately. Have a replacement dual-motor hot-swap fan ready to
install as soon as you remove the failed dual-motor hot-swap fan.
See System-board internal connectors for the locations of the dual-motor hot-swap
fan connectors.
To install any of the three replaceable fans, complete the following steps.
