Page: 83 / 258

Installation guidelines
Before you begin to install options in the server, read the following information:
v Become familiar with the information in “Handling electrostatic discharge-sensitive
devices” on page 204 and the safety guidelines provided in “Safety information”
on page 201. These guidelines will help you work safely while working with the
server or options.
v
The orange color on components and labels in the server identifies hot-swap or
hot-plug components. You can install or remove these components while the
system is running, provided that your system is configured to support this
function.
v The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
v 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.
v
Back up all-important data before you make changes to disk drives.
v For a list of supported options for the xSeries 440, refer to
http://www.ibm.com/pc/compat/ on the World Wide Web.
Working inside a server with power on
The server supports hot-swap devices and 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:
v 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.
v Do not allow your necktie or scarf to hang inside the server.
v
Remove jewelry, such as bracelets, rings, necklaces, and loose-fitting wrist
watches.
v
Remove items from your shirt pocket (such as pens or pencils) that could fall into
the server as you lean over it.
v
Take care to avoid dropping any metallic objects, such as paper clips, hair pins,
or screws, into the server.
System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has either a drive or a filler panel installed.
v There is space around the server to allow the cooling system to work properly.
v
Cables for optional adapters are routed according to the instructions that are
provided with the adapters.
v All microprocessors are the same size and clock speed.
v
When two SMP Expansion modules are installed, they are connected together
through the SMP Expansion Ports.
v An SMP baffle is installed on top of the lower SMP Expansion module when only
one module is installed.
v For proper cooling, do not leave the cover open for more than 30 minutes.
v A failed fan is replaced within 48 hours.
v The top cover is closed during normal operation.
v Do not remove a defective power supply until a replacement is available.
