Description

Electrostatic Discharge (ESD)

Observe and follow all ESD instructions while handling Tellabs plug-in equipment.

Caution! The Tellabs plug-in equipment uses semiconductor devices that can be damaged by electrostatic discharge (ESD). Do not remove a plug-in from a protective packing box or equipment rack until the time of installation or replacement. To equalize the static charge on the plug-in, establish a body path to the ground using an ESD wrist strap connected to a ESD ground. If storing or shipping the plug-in becomes necessary, place the plug-in in a conductive shipping box to prevent static buildup.]

Apply the following precautions:

• Use grounded wrist straps, table mats, floor mats
• Handle static-sensitive devices by the nonconductive areas
• Place static-sensitive cards into an antistatic plastic bag
• Use protective ESD-sensitive packing and shipping bags, when returning repairable components

Trouble Clearing

The probable causes of this alarm are: 

• Hardware Problem: The most common reason that the card cannot be downloaded is a hardware problem. The card should be rebooted to ensure the problem is not a software issue:
  • Reboot the card or ONT: If it downloads and the alarm clears, then the problem was a software issue.
  • Replace the Card or ONT: If this does not correct the problem, then it is likely a hardware issue.
  • Contact Tellabs Technical Assistance Center: If the Reboot and card replacement does not resolve the issue then there is likely to be a software upgrade issue, please contact Tellabs Technical Assistance Center for further guidance (refer to Contacting Technical Support).
• Software Problem: There may be issues with the software upgrade or incompatible releases. Run the diagnostics steps above. If they do not resolve the problem, contact Tellabs Technical Assistance Center (refer to Contacting Technical Support).
