CAUTION: Always handle a module by its edges. Do not touch the
components, pins, leads, or solder connections.
CAUTION: If you meet strong resistance when attempting to seat a module
using the ejectors, remove it from the chassis and confirm that the slot is
designed to hold the module. Also, be sure that you have aligned the top and
bottom edges in the correct matching card guides.
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.
You need the following tools to install a line module:
A No. 2 Phillips screwdriver
A flathead screwdriver
An ESD wrist strap or other grounding device
Before and during the installation process, observe the following precautions:
WARNING: Do not work on the system or connect or disconnect cables during
lightning activity.
WARNING: Be sure circuit breakers for the power source are in the OFF
position before attaching power cables.
WARNING: Remove jewelry (including rings, necklaces, and watches) before
working on equipment that is connected to power lines. Metal objects heat
up when connected to power and ground and can cause serious burns or
become welded to the terminals.
