The following information gives details about the controls, LEDs, and connectors on
the front of the server.
Hot-swap hard disk drive activity LED: This LED is used on SCSI hard disk
drives. Each hot-swap hard disk drive has an activity LED, and when this LED is
flashing, it indicates that the drive is in use.
Hot-swap hard disk drive status LED: This LED is used on SCSI hard disk
drives. When this LED is lit, it indicates that the drive has failed. If an optional IBM
ServeRAID™ controller is installed in the server, when this LED is flashing slowly
(one flash per second), it indicates that the drive is being rebuilt. When the LED is
flashing rapidly (three flashes per second), it indicates that the controller is
identifying the drive.
DVD-eject button: Press this button to release a DVD or CD from the DVD-ROM
drive.
DVD-ROM drive activity LED: When this LED is lit, it indicates that the DVD-ROM
drive is in use.

the hard disk drives is in use.
Note: Hard disk drive activity for the SCSI drives is shown in two places: on the
hard disk drive itself, and also on the hard disk drive activity LED on the
operator information panel.
There is no hard disk drive activity LED for the SATA drive. The only place
the SATA drive indicates hard disk drive activity is on the operator
information panel.
v Location LED: Use this blue LED to visually locate the server if it is in a location
with numerous other servers. You can use IBM Director to light this LED
remotely. This LED is controlled by the BMC.
v Information LED: When this amber LED is lit, it indicates that a non-critical
event has occurred. Check the light path diagnostics panel (see “Light path
diagnostics” on page 73) and the error log (see “POST error logs” on page 69).

Server power features
When the server is connected to an ac power source but is not turned on, the
operating system does not run, and all core logic except for the BMC is shut down;
however, the server can respond to requests from the BMC, such as a remote
request to turn on the server. The power-on LED flashes to indicate that the server
is connected to ac power but not turned on.
Turning on the server
When you connect the server to an ac power source, the power supply fans turn on
immediately; then, approximately 20 seconds later, the power-control button
becomes active and you can turn on the server and start the operating system by
pressing the power-control button.
The server can also be turned on in any of the following ways:
v If a power failure occurs while the server is turned on, the server will restart
automatically when power is restored.
v If the operating system supports the system-management software for an
optional Remote Supervisor Adapter II SlimLine option, the system-management
software can turn on the server.
v If the operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the server.
Turning off the server
When you turn off the server and leave it connected to ac power, the power supply
fans continue to run and the server can respond to requests from the BMC, such as
a remote request to turn on the server. To remove all power from the server, you
must disconnect it from the power source.
Some operating systems require an orderly shutdown before you turn off the server.
See the operating-system documentation for information about shutting down the
operating system.

Chapter 3. Customer replaceable units
This chapter provides instructions for installing, removing, and connecting optional
devices that the server supports.
Installation guidelines
Before you begin installing options, read the following information:
v Read Appendix B, “Safety information,” on page 129 and the guidelines in
“Handling static-sensitive devices” on page 16. This information will help you
work safely with the server and options.
v Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and other devices.
v Back up all important data before you make changes to disk drives.
v You do not have to turn off the server to install or replace hot-swap power
supplies or hot-swap fans.
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 For a list of supported options for the server, go to http://www.ibm.com/servers/
eserver/serverproven/compat/us/.
System reliability considerations
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 (2.0 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 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 When replacing a hot plug fan, you have 5 minutes to install the new fan or the
server will shut down.
v You have replaced a hot-swap drive within 2 minutes of removal.
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:
© Copyright IBM Corp. 2002, 2007 15
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 let 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.
Handling static-sensitive devices
Attention: Static electricity can damage the server and other electronic devices.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Wear an electrostatic-discharge wrist strap, if one is available.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the server for at least 2 seconds. This drains static electricity from
the package and from your body.
v Remove the device from its package and install it directly into the server without
setting down the device. If it is necessary to set down the device, put it back into
its static-protective package. Do not place the device on the server cover or on a
metal surface.
v Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
