Chapter 2
System Safety
2-1 Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following the steps in order given should enable you to have your chassis set up
and operational within a minimal amount of time. This quick setup assumes that you
are an experienced technician, familiar with common concepts and terminology.
2-2 Warnings and Precautions
You should inspect the box the chassis was shipped in and note if it was damaged
in any way. If the chassis itself shows damage, le a damage claim with carrier
who delivered your system.
Decide on a suitable location for the rack unit that will hold that chassis. It should
be situated in a clean, dust-free area that is well venilated. Avoid areas where heat,
electrical noise and eletromagnetic elds are generated.
The system must be placed near at two grounded power outlets. When congured,
the SC847J chassis includes one primary and one redundant power supply.
2-3 Preparing for Setup
The SC847J chassis includes a set of rail assemblies which includes mounting
brackets and mounting screws you will need to install the systems into the rack.
Please read this manual in its entirety before you begin the installation proce-
dure.

SC847J Chassis Manual
2-2
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC847J from damage:
Be aware of the locations of the power on/off switch on the chassis as well•
as the room’s emergency power-off switch, disconnection switch or electrical
outlet. If an electrical accident occurs, you can then quickly remove power from
the system.
Do not work alone when working with high-voltage components.•
Power should always be disconnected from the system when removing or install-•
ing main system components, such as the serverboard, memory modules (not
necessary for hot swappable drives). When disconnecting power, you should rst
power down the system with the operating system and then unplug the power
cords from all the power supply modules in the system.
When working around exposed electrical circuits, another person who is fa-•
miliar with the power-off controls should be nearby to switch off the power, if
necessary.
Use only one hand when working with powered-on electrical equipment. This•
is to avoid making a complete circuit, which will cause electrical shock. Use
extreme caution when using metal tools, which can easily damage any electrical
components or circuit boards they come into contact with.
Do not use mats designed to decrease electrostatic discharge as protection from•
electrical shock. Instead, use rubber mats that have been specically designed
as electrical insulators.
The power supply power cord must include a grounding plug and must be•
plugged into grounded electrical outlets.
Serverboard battery: CAUTION - There is a danger of explosion if the onboard•
battery is installed upside down, which will reverse its polarities This battery
must be replaced only with the same or an equivalent type recommended by
the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.

2-3
Chapter 2: System Safety
Please handle used batteries carefully. Do not damage the battery in any way;•
a damaged battery may release hazardous materials into the environment. Do
not discard a used battery in the garbage or a public landll. Please comply
with the regulations set up by your local hazardous waste management agency
to dispose of your used battery properly.
2-5 General Safety Precautions
Keep the area around the chassis clean and free of clutter.•
Place the chassis top cover and any system components that have been re-•
moved away from the system or on a table so that they won’t accidentally be
stepped on.
While working on the system, do not wear loose clothing such as neckties and•
unbuttoned shirt sleeves, which can come into contact with electrical circuits or
be pulled into a cooling fan.
Remove any jewelry or metal objects from your body, which are excellent metal•
conductors that can create short circuits and harm you if they come into contact
with printed circuit boards or areas where power is present.
After accessing the inside of the system, close the system back up and secure•
it to the rack unit with the retention screws after ensuring that all connections
have been made.
2-6 System Safety
Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to
neutralize this difference, which can damage electronic components and printed
circuit boards. The following measures are generally sufcient to neutralize this
difference before contact is made to protect your equipment from ESD:
Do not use mats designed to decrease electrostatic discharge as protection from•
electrical shock. Instead, use rubber mats that have been specically designed
as electrical insulators.
Use a grounded wrist strap designed to prevent static discharge.•
Keep all components and printed circuit boards (PCBs) in their antistatic bags•
until ready for use.

SC847J Chassis Manual
2-4
Touch a grounded metal object before removing any board from its antistatic•
bag.
Do not let components or PCBs come into contact with your clothing, which may•
retain a charge even if you are wearing a wrist strap.
Handle a board by its edges only; do not touch its components, peripheral chips,•
memory modules or contacts.
When handling chips or modules, avoid touching their pins.•
Put the serverboard and peripherals back into their antistatic bags when not•
in use.
For grounding purposes, make sure your computer chassis provides excellent•
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.

System Interface
3-1 Overview
There are several LEDs on the control panel as well as others on the drive carriers
to keep you constantly informed of the overall status of the system as well as the
activity and health of specic components. SC847J models have two buttons on
the chassis control panel: A reset button and a power on/off switch. This chapter
explains the meanings of all LED indicators and the appropriate responses you
may need to take.
Figure 3-1: Control Panel

SC847J Chassis Manual
3-2
3-3 Control Panel LEDs
The control panel located on the left handle of the SC847J chassis has ve LEDs.
These LEDs provide you with critical information related to different parts of the
system. This section explains what each LED indicates when illuminated and any
corrective action you may need to take.
Power: The main power button is used to apply or remove power from the power
supply to the server system. Turning off system power with this button removes
the main power but keeps standby power supplied to the system. Therefore, you
must unplug system before servicing.
3-2 Control Panel Buttons
There are two push-buttons located on the left handle of the chassis. These are
(in order from top to bottom) a power on/off button and a reset button.
Power: Indicates power is being supplied to the system's power supply units. This
LED should normally be illuminated when the system is operating.
HDD: Indicates IDE channel activity. SAS/SATA drive, and/or DVD-ROM drive
activity when ashing.
Reset: The reset button is used to reboot the system.

Power Failure: When this LED ashes, it indicates a failure in the redundant power
supply.
Overheat/Fan Fail: When this LED ashes, it indicates a fan failure. When con-
tinuously on (not ashing) it indicates an overheat condition, which may be caused
by cables obstructing the airow in the system or the ambient room temperature
being too warm. Check the routing of the cables and make sure all fans are pres-
ent and operating normally. You should also check to make sure that the chassis
covers are installed. Finally, verify that the heatsinks are installed properly. This
LED will remain ashing or on as long as the overheat condition exists.

SC847J Chassis Manual

3-4 Drive Carrier LEDs
Your chassis uses SAS/SATA.
SAS/SATA Drives
Each SAS/SATA drive carrier has two LEDs.
Blue:•
Solid on = Drive is present and available.
Blinking = Drive is actively being accessed.
Each Serial ATA drive carrier has a blue LED. When illuminated in a solid
on state, this blue LED (on the front of the SAS/SATA drive carrier) indicates
drive activity. A connection to the SAS/SATA backplane enables this LED to
blink on and off when that particular drive is being accessed.
Red:•
Solid on = Drive failure
Blinking = RAID activity
When the red LED is blinking, it indicates that the system is either building,
initializing or rebuilding RAID.
SCSI Drives
This chassis does not support SCSI drives at this time.
