Tyan Computer B5382 manual Precautions

2.1.3Precautions

Components and electronic circuit boards can be damaged by discharges of static electricity. Working on a system that is connected to a power supply can be extremely dangerous. Follow the guidelines below to avoid damage to the Tank FT48-B5382 or injury to yourself.

•Ground yourself properly before removing the top cover of the system. Unplug the power from the power supply and then touch a safely grounded object to release static charge (i.e. power supply case). If available, wear a grounded wrist strap. Alter- natively, discharge any static electricity by touching the bare metal chassis of the unit case, or the bare metal body of any other grounded appliance.

•Avoid touching motherboard components, IC chips, connectors, memory modules, or leads.

•The motherboard is pre-installed in the system. When removing the motherboard, always place it on a grounded anti-static surface until you are ready to reinstall it.

•Hold electronic circuit boards by the edges only. Do not touch the components on the board unless it is necessary to do so. Do not flex or stress circuit boards.

•Leave all components inside the static-proof packag- ing that they ship with until they are ready for installa- tion.

•After replacing optional devices, make sure all screws, springs, or other small parts are in place and are not left loose inside the case. Metallic parts or metal flakes can cause electrical shorts.

•Always use the correct size screws and fixings when installing or replacing components.

Notes:

•All connectors are keyed to only attach one way.

•Always use the correct screw size as indicated in the procedures.
