v Make sure that you have an adequate number of properly grounded electricaloutlets for the server, monitor, and other devices.v Back up all important data before you make changes to disk drives.v Have a small flat-blade screwdriver available.v You do not have to turn off the server to install or replace hot-swap powersupplies, hot-plug adapters, or hot-plug Universal Serial Bus (USB) devices.However, you must turn off the server before performing any steps that involveremoving or installing system-board cables.v Blue on a component indicates touch points, where you can grip the componentto remove it from or install it in the server, open or close a latch, and so on.v Orange on a component or an orange label on or near a component indicatesthat the component can be hot-swapped, which means that if the server andoperating system support hot-swap capability, you can remove or install thecomponent while the server is running. (Orange can also indicate touch points onhot-swap components.) See the instructions for removing or installing a specifichot-swap component for any additional procedures that you might have toperform before you remove or install the component.v When you are finished working on the server, reinstall all safety shields, guards,labels, and ground wires.v For a list of supported optional devices for the server, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.System reliability guidelinesTo help ensure proper cooling and system reliability, make sure that:v Each of the drive bays has a drive or a filler panel installed in it.v If the server has redundant power, each of the power-supply bays has a powersupply installed in it.v There is adequate space around the server to allow the server cooling system towork properly. Leave approximately 50 mm (2 in.) of open space around the frontand rear of the server. Do not place objects in front of the fans. For propercooling and airflow, replace the server cover before turning on the server.Operating the server for extended periods of time (more than 30 minutes) withthe server cover removed might damage server components.v You have followed the cabling instructions that come with optional adapters.v You have replaced a failed fan within 48 hours.v You have replaced a hot-swap drive within 10 minutes of removal.v You do not run the server without the air baffle installed. Operating the serverwithout the air baffle might cause the microprocessor to overheat.v The microprocessor socket always contains a microprocessor and fan sink.v For redundant and hot-swappable operation on some models, the power suppliesare connected to 200-240 V ac.74 System x3200 Types 4362 and 4363: Problem Determination and Service Guide
