IMPORTANT: The requirement of extending or removing the server from the rack when 
performing installation and maintenance procedures depends on the rail system used: 
•  If using a ball-bearing rail system, you can perform most installations and maintenance by 
simply extending the server from the rack. 
•  If using a friction rail system, to perform installations or maintenance that requires access panel 
removal, remove the server from the rack. 
 
To extend the server from an HP, Compaq-branded, Telco, or third-party rack: 
1.  Power down the server (on page 17). 
2.  Remove all power: 
a.  Disconnect each power cord from the power source. 
b.  Disconnect each power cord from the server. 
3.  Disconnect all peripheral cables. 
 
 
WARNING: To reduce the risk of personal injury or equipment damage, be sure that the rack is 
adequately stabilized before extending a component from the rack. 
 
 
 
WARNING: To reduce the risk of personal injury, be careful when pressing the server rail-release 
latches and sliding the server into the rack. The sliding rails could pinch your fingers. 
 
4.  Pull down the quick release levers on each side of the server. 
5.  Extend the server on the rack rails until the server rail-release latches engage. 
If the server does not extend from the rack, use a T-25 Torx screwdriver to loosen the screws located 
within the lever housing. 
6.  After performing the installation or maintenance procedure, slide the server into the rack. For more 
information, see the documentation that ships with the rack-mounting option. 
7.  Connect the peripheral cables. 
8.  Connect each power cord to the server. 
9.  Connect each power cord to the power source.

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.
