Compatibility Data
The Compatibility Data tool gives the user access to hardware configuration data
that is compatible to a user-specified software generic.
News and Bulletin
The News and Bulletin tool allows the user to process News and Bulletin infor-
mation. News consists of messages that may be of general interest to the user.
Bulletins contain information of a more urgent nature.
Circuit Pack Failures
Circuit pack failures are identified by LEDs and reported by FT-2000 network alarms
and reports.
Circuit packs are replaced in a specified sequence, but only one circuit pack is
replaced at a time. If trouble is not cleared after replacing a circuit pack, the original
circuit pack should be reinstalled. This reduces the chances of returning
nondefective circuit packs for repair.
Electrostatic Discharge (ESD) Considerations
Any integrated circuit on a circuit pack can be damaged by static electricity that builds
up within a work area, particularly in areas with low relative humidity. This static
buildup on work surfaces and on personnel and their clothing is produced by the
various charging effects of even simple movements and by contact between various
objects.
As a rule, the greatest potential for electrostatic damage occurs in areas with the
lowest relative humidity. But, because such damage can occur anywhere, all
personnel handling circuit packs should take the following precautions:
1. Since materials such as food wrappers, plastics, and Styrofoam containers
tend to generate static electricity, keep them away from all circuit packs.
2. Be sure to read all warning labels on bags and cartons before opening any
packaging.
3. If possible, open all circuit packs at a static-safe work position using properly
grounded wrist straps and table mats that can dissipate static electricity.
4. Whenever possible, wait to remove circuit packs from their protective antistatic
packaging until it is time to insert them into a shelf.
5. Never touch a circuit pack's components, conductors, or connector pins. Han-
dle all circuit packs only by the faceplate or latch or by the top and bottom out-
ermost edges.
