Visually Checking Your Server - HP 1850R - ProLiant - 128 MB RAM Troubleshooting Manual

•
Restock spare parts as they are used.
•
Do not clean card edge connectors with erasers; it removes the gold, causes static
discharge, and leaves residue. If connectors have to be cleaned, use isopropyl
alcohol or a special cleaning solution applied with a cotton-tipped swab.

Visually Checking Your Server

Periodically you should look at the following items on your server. A visual check
can prevent many problems.
•
Be sure that systems and racks are not positioned tightly up against walls and that
there is adequate space around them for proper airflow.
•
Move magnetized office items such as magnetized screwdrivers and telephones
with electromagnetic ringers away from the system.
•
Be sure the server does not share a power line with high-current machines, such
as laser printers, air conditioners, copiers, and coffee machines, or ungrounded
power strips.
•
Periodically check AC grounded (earthed) outlets to see if they are in need of
repair.
•
Take the system cover off, and then remove any dust buildup with a can of
compressed air, tighten any loose connections, reseat boards, and inspect any
cables for frays. Move the cables away from sources of heat and give them more
slack if possible.
•
Check for adequate airflow and dislodge anything blocking the fans.
•
Check for dust on external server parts, such as fans.
•
Check your server after power disruptions due to acts of nature. Refer to the
"Recognizing Power Problems Caused by Acts of Nature" section in this chapter.
