Removal and replacement procedures 26
WARNING: This server is very heavy. To reduce the risk of personal injury or damage to the
equipment:
• Observe local occupational health and safety requirements and guidelines for manual
material handling.
• Get help to lift and stabilize the product during installation or removal, especially when the
product is not fastened to the rails. HP recommends that a minimum of two people are required
for all rack server installations. A third person may be required to help align the server if the
server is installed higher than chest level.
• Use caution when installing the server in or removing the server from the rack; it is unstable
when not fastened to the rails.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment,
remove the power cord to remove power from the server. The front panel Power On/Standby
button does not completely shut off system power. Portions of the power supply and some internal
circuitry remain active until AC/DC power is removed.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply. 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 long periods with the access panel open or removed.
Operating the server in this manner 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 perform one or more of the
following procedures:
• Power down the server (on page 27).
If you must remove a server from a rack or a non-hot-plug component from a server, power down the
server.
• Extend the server from the rack (on page 27).
If you are performing service procedures in an HP, Compaq-branded, Telco, 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.
For more information about Telco rack solutions, see the RackSolutions website
(http://www.racksolutions.com/hp).
• Remove the server from the rack (on page 28).
If the rack environment, cabling configuration, or the server location in the rack creates awkward
conditions, remove the server from the rack.
