v When you are finished working on the server, reinstall all safety shields, guards,

labels, and ground wires.

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 and 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 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 server cover before turning on the server.

Operating the server for extended periods of time (more than 30 minutes) with

the server 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 10 minutes of removal.

v You do not run the server without the air baffle installed. Operating the server

without the air baffle might cause the microprocessor to overheat.

v The microprocessor socket always contains a microprocessor and heat sink.

v For redundant and hot-swappable operation, the power supplies are connected to

200-240 V ac.

Working inside the server with the power on

Attention: Static electricity that is released to internal server components when

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-plug, hot-add, and 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 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, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that could fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.
