– Distribute the weight of the object equally between your feet.– Use a slow lifting force. Never move suddenly or twist when you lift a heavyobject.– To avoid straining the muscles in your back, lift by standing or by pushing upwith your leg musclesv 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 and a small Phillips screwdriver available.v You do not have to turn off the server to install or replace hot-swap powersupplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.However, you must turnoff the server before you perform any steps that involveremoving or installing adapter cables or non-hot-swap optional devices orcomponents.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 the followingrequirements are met:v Each of the drive bays has a drive or a filler panel and electromagneticcompatibility (EMC) shield 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 you turn 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 2 minutes of removal.v You do not operate the server without the air baffles installed. Operating theserver without the air baffles might cause the microprocessor to overheat.v For redundant operation, the power supplies are connected to 200 - 240 V ac.58 IBM System x3350 Type 4192 and 4193: Problem Determination and Service Guide
