Chapter 1: Safety Guidelines

Chapter 1Safety Guidelines

To avoid personal injury and property damage, carefully follow all the safety steps
listed below when accessing your system or handling the components.

1-1

ESD Safety Guidelines

Electrostatic Discharge (ESD) can damage electronic com­ponents. To prevent damage to your system, it is important to handle it very carefully. The following measures
are generally sufficient to protect your equipment from ESD.

• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing a component from the antistaticbag.

• Handle the midplane by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.
• Put the card and peripherals back into their antistatic bags when not in use.
1-2

General Safety Guidelines• Always disconnect power cables before installing or removing any components
from the computer, including the BPN-NVMe3-227SSB series midplane.

• Make sure that the midplane is properly and securely on the motherboard toprevent damage to the system due to power outages.
