Preventing Electrostatic Discharge Damage - HP Aruba 6400 Series Installation And Getting Started Manual

• Remove all power supplies, line and management modules, fan trays, and all external cables, including
the power cords, before moving the chassis.
• Use a minimum of four people to manually move a chassis weighing more than 100 lbs, and a minimum
of two people to manually move a chassis weighing less than 100 lbs. To determine chassis weight, see
Aruba 6400 product weights.
• Lift and lower the chassis slowly. Never move it suddenly.
For information and recommended practices for moving the chassis, see Unpacking, lifting, and moving
the chassis.

Preventing electrostatic discharge damage

Be aware of the precautions you must follow when setting up the switch or handling components. A
discharge of static electricity from a finger or other conductor may damage system boards or other static-
sensitive devices. This type of damage may reduce the life expectancy of the switch or component.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always use a properly grounded ESD wrist strap when touching static-sensitive components or
assemblies.
Use one or more of the following methods when handling or installing electrostatic-sensitive parts:
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when
standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
• Use an ESD wrist strap connected to an ESD connection point on the switch (see the following image).
Wrist straps are flexible straps with a minimum of 1 megohm ±10 percent resistance. To provide proper
