42 Hardware Maintenance Manual: xSeries 330
Before you begin
Before you begin to install options in the server, read the following information:
• Become familiar with the safety and handling guidelines specified under
“Handling electrostatic discharge-sensitive devices” on page 110, and read the
safety statements in “Safety information” on page 107. These guidelines will help
you work safely while working with the server or options.
• Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and any other options that you intend to install.
• Back up all important data before you make changes to disk drives.
• Have a small, flat-blade screwdriver available.
• For a list of supported options for the server, refer to
http://www.ibm.com/pc/us/compat on the World Wide Web.
• For your convenience during setup and service you might want to have a
separate location where you can temporarily connect the server to a power source
(using a separate power cord), keyboard, monitor, and mouse (using a separate
C2T device breakout cable). Additional C2T cables are available in the cable
option kit.
System reliability considerations
To help ensure proper cooling and system reliability, make sure:
• Each of the drive bays has either a drive or a filler panel installed.
• The cover is in place during normal operations, or is removed for no longer than
30 minutes while the server is operating.
• There is space around the server to allow the server cooling system to work
properly. Leave about 127 mm (5 in.) of space around the front and rear of the
server.
• Cables for optional adapters are routed according to the instructions provided
with the adapters.
• A failed fan is replaced within 48 hours.
Working inside a server with power on
Your server is designed to operate safely while turned on with the cover removed.
Follow these guidelines when you work inside a server that is turned on:
• Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before
working inside the server; do not wear cuff links while you are working inside the
server.
• Do not allow your necktie or scarf to hang inside the server.
• Remove jewelry, such as bracelets, rings, necklaces, and loose-fitting wrist
watches.
• Remove items from your shirt pocket (such as pens or pencils) that could fall into
the server as you lean over it.
• Take care to avoid dropping any metallic objects, such as paper clips, hair pins, or
screws, into the server.
