devices. However, you must turn off the server before performing any steps that

involve removing or installing adapter cables or non-hot-swap optional devices or

components.

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

labels, and ground wires.

v For a list of supported optional devices for the server, see

v When working inside the server, you might find some tasks easier if you lay the

server on its side.

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 duct or air baffles while the server is running.

Operating the server without the air duct or air baffles might cause the

microprocessor to overheat.

v Microprocessor socket 2 always contains either a microprocessor duct or a

microprocessor and heat sink.

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 might result in the

loss of data. To avoid this potential problem, always use an electrostatic-discharge

wrist strap or other grounding system when you work 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:
