Removal and Replacement Procedures
2-3
CAUTION:
Always begin by mounting the heaviest item on the bottom of the rack. Continue to
populate the rack from the bottom to the top.
Server Warnings and Cautions
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the hot-plug drives
and the internal system components to cool before touching.
WARNING:
To reduce the risk of electrical shock or damage to the equipment:
■
Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
■
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.
■
Unplug the power cord from each power supply to disconnect power to the equipment.
WARNING:
Because the rack allows you to stack computer components in a vertical rather
than a horizontal plane, you must take precautions to provide for rack stability and safety to
protect both personnel and property. Heed all cautions and warnings throughout the installation
instructions that came with the server.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from damage
caused by power surges and voltage spikes and keeps the system in operation during a power
failure
CAUTION:
Do not operate the server for extended periods without the access panel. Operating
the server without the access panel results in improper airflow and improper cooling that can
lead to thermal damage.
Preparation Procedures
To access some components and perform certain service procedures, you must do one or more
of the following:
■
Extend the server from the rack.
If you are performing service procedures in a Compaq rack or third-party rack cabinet,
you can use the locking feature of the rack rails to support the server and gain access to
internal components.
■
Power down the server.
If you must remove a server from a rack or a non-hot-plug component from a server,
power down the server.
■
Remove the server from the rack.
If the rack environment, cabling configuration, or the server location in the rack creates
awkward conditions, remove the server from the rack. If your server is installed in a Telco
rack, you must remove the server from the rack to access internal components.
