1 Working on your thin client Safety instructions Prerequisites Use the following safety guidelines to protect your thin client from potential damage and to ensure your personal safety. Unless otherwise noted, each procedure included in this document assumes that the following conditions exist: • • You have read the safety information that shipped with your thin client. A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.
4. Disconnect all network cables from your thin client. 5. Disconnect all attached devices and peripherals, such as keyboard, mouse, and monitor, from your thin client. Safety precautions The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions. Observe the following safety precautions before you perform any installation or break/fix procedures involving disassembly or reassembly: • • • • • • Turn off the system and all attached peripherals.
• Before transporting a static-sensitive component, place it in an anti-static container or packaging. ESD field service kit The unmonitored Field Service kit is the most commonly used service kit. Each Field Service kit includes three main components: antistatic mat, anti-static wrist strap, and bonding wire.
CAUTION: Do not lift greater than 50 pounds. Always obtain additional resources or use a mechanical lifting device. 1. 2. 3. 4. 5. Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out. Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load. Lift with your legs, not your back. Keep the load close. The closer it is to your spine, the less force it exerts on your back.
