Warning Read the installation instructions before you connect the system to its power source.
Warning When carrying emergency (911) traffic, the MGX 8260 must be powered from redundant uninterruptible power sources.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled and can result in complete or intermittent system failures.
Use an antistatic strap (clipped to a grounded rack) whenever handling all cards.
To prevent ESD damage, follow these guidelines:
•Always use an ESD wrist strap or ankle strap and ensure that it makes good skin contact.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 Mohms.
•When handling circuit cards or cables, make sure the equipment end of your ESD strap is attached to an unfinished chassis surface of the device in which it is housed. Do not touch the printed circuit board, and avoid contact between the printed circuit board and your clothing.
•Always place circuit boards
•Ensure that all circuit cards are fully inserted into their respective chassis slots, the respective extraction levers are in the locked position, and the captive installation screws are hand tightened. The captive installation screws prevent accidental removal, provide proper grounding for the system, and help to seat the bus connectors in the receptacles.
