v Have a small flat-blade screwdriver available.
v You do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap hard disk drives, hot-swap fans, or hot-plug Universal Serial
Bus (USB) devices.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the server, open or close a latch, and so on.
v Orange on a component or an orange label on or near a component indicates
that the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on
hot-swap components.) See the instructions for removing or installing a specific
hot-swap component for any additional procedures that you might have to
perform before you remove or install the component.
v When you have to access the inside of the server, you might find it easier to lay
the server on its side.
v You can install a maximum of two IDE devices in the server.
v For a list of supported optional devices for the server, go to http://www.ibm.com/
servers/eserver/serverproven/compat/us/.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that the following
requirements are met:
v Each of the drive bays has a drive or an electromagnetic compatibility (EMC)
shield installed in it.
v If the server has redundant power, each of the power-supply bays has a power
supply installed in it.
v There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2.0 in.) of open space around the
front and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the left-side cover before you turn on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the left-side cover removed might damage server components.
v You have followed the cabling instructions that come with optional adapters.
v You have replaced a failed fan within 48 hours.
v You have replaced a hot-swap drive within 2 minutes of removal.
v You do not remove the air ducts or air baffles while the server is running.
Operating the server without the air ducts or air baffles might cause the
microprocessor to overheat.
v Microprocessor socket 2 always contains either a microprocessor baffle or a
microprocessor and heat sink.
Working inside the server with the power on
The server supports hot-swap devices and is designed to operate safely while it is
turned on and the cover is removed. Follow these guidelines when you work inside
a server that is turned on:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts
before you work 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, necklaces, rings, and loose-fitting wrist
watches.
