Installation
3-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic components. To avoid dam-
aging your add-on card, it is important to handle it very carefully. The following
measures are generally sufcient to protect your equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the add-on card from the
antistatic bag.
• Handle the add-on card by its edges only; do not touch its components.
• Put the add-on card back into the antistatic bags when not in use.
• For grounding purposes, make sure that your system chassis provides excel-
lent conductivity between the power supply, the case, the mounting fasteners,
and the add-on card.
Unpacking
The add-on card is shipped in antistatic packaging to avoid static damage. When
unpacking your component or system, make sure that you are static protected.
Note: To avoid damaging your components and to ensure proper instal-
lation, always connect the power cord last, and always unplug it before
adding, removing or changing any hardware components.

3-2
Super AOC-M25G-i2S(M) Add-on Card User's Guide
3-2 Before Installation
Before you install the add-on card, follow the instructions below.
1. Power down the system.
2. Unplug the power cord.
3. Use industry-standard anti-static equipment such as gloves or a wrist strap
and follow the precautions on previous page to avoid damage caused by
ESD.
4. Familiarize yourself with the server, motherboard, and/or chassis documenta-
tion.
5. Conrm that your operating system includes the latest updates and hotxes.
