Preventing Electrostatic Discharge Damage - Cisco UCS 6248 UP Installation Manual

Preventing Electrostatic Discharge Damage

Note In all situations, grounding practices must comply with local National Electric Code (NEC) requirements or
local laws and regulations.
Note Always ensure that all of the modules are completely installed and that the captive installation screws are
fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices
are normal installation practices and must be followed in all installations.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when modules or other devices are improperly handled,
results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal
carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier.
Although the metal carrier helps to protect the board from ESD, always use an ESD grounding strap when
handling modules.
For preventing ESD damage, follow these guidelines:
• Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin.
• ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. All Cisco
• If you choose to use the disposable ESD wrist strap supplied with most field-replaceable units or an ESD
• If your chassis does not have the system ground attached, you must install the system ground lug. See
Before you install the system ground lug, you must correctly attach the ESD wrist strap.
