To protect the modules and slots when installing modules, observe the following
guidelines:
CAUTION: When handling modules, use an antistatic wrist strap connected
to the router's ESD grounding jack. This action helps to protect the module
from damage by electrostatic discharge.
CAUTION: Always handle the module by its edges. Do not touch the
components, pins, leads, or solder connections.
CAUTION: If you meet strong resistance when attempting to seat the module
using the ejectors, remove it from the chassis and confirm that the slot is
designed to hold the module. Then verify, if applicable, that the module
matches its corresponding module (I/O module or line module). Also, be sure
that you have aligned the top and bottom edges in the correct matching
tracks.
CAUTION: Be sure to cover every empty slot with a blank filler panel to protect
the system from dust or other foreign substances and to ensure proper system
cooling.
CAUTION: Do not discard the antistatic bag. When a module is not in use,
store it in an antistatic bag.
Before you attempt to install or replace a line module (inserted in the front of the chassis),
make sure the corresponding I/O module (inserted in the rear of the chassis) is already
in place. The slot diagnostics run when a line module is installed in a chassis slot. If the
