Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the appliance. To prevent static damage, discharge
static electricity from your body before you touch any of your system's electronic components. You can
do so by touching an unpainted metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):

Understanding the Environmental Requirements
To ensure continued safe and reliable equipment operation, install or position the system in a
well-ventilated, climate-controlled environment.

Each of the drive bays has either a drive or a filler panel installed.
The Interface Module bay has either a Cisco Interface Module or a filler panel installed.
For rack configurations, make sure that space is available around the appliance to enable the cooling
system to work properly. See the documentation that comes with the rack for additional information.
A removed hot-swappable drive is replaced within 1 minute of removal.
Cables for optional adapters are routed according to the instructions provided with the adapters.
A failed fan is replaced within 48 hours.
When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the component in your
system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from
your body.
When transporting a sensitive component, first place it in an antistatic container or packaging.
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and
workbench pads.
Handle the appliance carefully, holding it by its edges or its frame.
Do not touch solder joints, pins, or exposed printed circuitry.
Do not leave the appliance where others can handle and possibly damage the appliance.
Take additional care when handling appliances during cold weather, because heating reduces indoor
humidity and increases static electricity.
