The technician makes decisions regarding trouble analysis, corrective
action, and obtaining assistance. The technician and the local technical
support staff may choose to continue trouble analysis based on
knowledge or experience with LambdaXtreme Transport, or they may
elect to obtain assistance by calling Customer Technical Assistance
Management (CTAM) 1-800 225 4672 (United States) and 1-630
224-4672 (International), in accordance with local procedures.
Circuit pack failures are identified by constantly lit LEDs and reported
by network alarms and reports.
Circuit packs are replaced in a specified sequence, but only one
circuit pack is replaced at a time. If a 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.
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 must adhere to
the following precautions:
1. Keep all food wrappers, plastics, and Styrofoam containers away
from all circuit packs.
2. Read all warning labels on bags and cartons containing electronic
components before opening.
3. If possible, open all circuit packs at a static-safe work position
using properly grounded wrist straps and table mats that dissipate
static electricity.
4. Whenever possible, wait to remove circuit packs from their
protective antistatic packaging until time to insert them into a
shelf.
5. Never touch a circuit pack's components, conductors, or
connector pins. Handle all circuit packs only by the faceplate or
latch, or by the top and bottom outermost edges.
