Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur
when electronic printed circuit cards are improperly handled and can cause complete or intermittent
failures. Always follow ESD-prevention procedures when removing and replacing modules:
•
•
•
•
•
•
For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It

should be between 1 and 10 Mohm.

Lifting Guidelines

The CSACS 1120 Series appliance weighs between 15 lb (9.071 kg) and 33 lb (14.96 kg) depending on
what hardware options are installed in the appliance. The appliance is not intended to be moved
frequently. Before you install the appliance, ensure that your site is properly prepared so you can avoid
having to move the appliance later to accommodate power sources and network connections.
Whenever you lift the appliance or any heavy object, follow these guidelines:

Preparing Your Site for Installation

Before installing the CSACS 1120 Series appliance, it is important to prepare the following:

OL-19455-01
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
appliance. 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.
Ensure that the CSACS 1120 Series appliance is electrically connected to earth ground.
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to
an unpainted surface of the appliance to channel unwanted ESD voltages safely to ground. To guard
against ESD damage and shocks, the wrist strap and cord must operate effectively.
If no wrist strap is available, ground yourself by touching a metal part of the appliance.
Always disconnect all external cables before lifting or moving the appliance.
Ensure that your footing is solid, and balance the weight of the object between your feet.
Lift the appliance slowly; never move suddenly or twist your body as you lift.
Keep your back straight and lift with your legs, not your back. If you must bend down to lift the
appliance, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.
Lift the appliance from the bottom; grasp the underside of the appliance exterior with both hands.
Prepare the site (see Site Planning, page
procedures (MOPs).
Unpack and inspect the appliance.
Gather the tools and test equipment required to properly install the appliance.
