 Troubleshooting 
81 
 
 
 
Observe local occupation health and safety requirements and 
guidelines for manual handling. 
 
Obtain adequate assistance to lift and stabilize the chassis 
during installation or removal. 
 
The server is unstable when not fastened to the rails. 
 
When mounting the server in a rack, remove the power 
supplies and any other removable module to reduce the overall 
weight of the product.
 
 
  CAUTION:  To properly ventilate the system, you must provide at 
least 7.6 cm (3.0 in) of clearance at the front and back of the server. 
 
  CAUTION:  The server is designed to be electrically grounded 
(earthed). To ensure proper operation, plug the AC power cord into a 
properly grounded AC outlet only. 
 
Preparing the server for diagnosis 
1.
  Be sure the server is in the proper operating environment with adequate 
power, air conditioning, and humidity control. Refer to the server 
documentation for required environmental conditions. 
2.
  Record any error messages displayed by the system. 
3.
  Remove all diskettes and CDs from the media drives. 
4.
  Power down the server and peripheral devices if you will be diagnosing the 
server offline. Always perform an orderly shutdown, if possible. This means 
you must: 
a.
  Exit any applications. 
b.
  Exit the operating system. 
c.
5.
  Disconnect any peripheral devices not required for testing (any devices not 
necessary to power up the server). Do not disconnect the printer if you want 
to use it to print error messages. 
6.
  Collect all tools and utilities, such as a Torx screwdriver, loopback adapters, 
ESD wrist strap, and software utilities, necessary to troubleshoot the 
problem.
