System reliability guidelines
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has a drive or a filler panel installed in it.
v If the server has redundant power, each of the power-supply bays has a power
v There is adequate space around the server to allow the server cooling system to
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 run the server without the air baffle installed. Operating the server
v Microprocessor sockets 2, 3, and 4 each always contain either a microprocessor
v For redundant and hot-swappable operation, the power supplies are connected to
Working inside the server with the power on
Attention:
the server is powered-on might cause the server to halt, which could result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when 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
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
v Remove items from your shirt pocket, such as pens and pencils, that could fall
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
Handling static-sensitive devices

To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
