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 performing most maintenance tasks.
Reset Button
The reset button is located below the power button and allows you to manually
reset the system.
4-3 Control Panel LEDs
There are four control panel LEDs that provide status information about the system.

To avoid personal injury and property damage, carefully follow all the safety steps
listed below when accessing your system or handling the components.
B-1 ESD Safety Guidelines
Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent dam-
age to your system, it is important to handle it very carefully. The following measures
are generally sufcient to protect your equipment from ESD.
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing a component from the antistatic
bag.
• Handle the backplane by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the card and peripherals back into their antistatic bags when not in use.
B-2 General Safety Guidelines
• Always disconnect power cables before installing or removing any components
from the computer, including the BPN-SAS-733TQ backplane.
• Disconnect the power cable before installing or removing any cables from the
backplane.
• Make sure that the BPN-SAS-733TQ backplane is securely and properly in-
stalled on the motherboard to prevent damage to the system due to power
shortage.

Explanation of Jumpers
To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identied with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
*The buzzer sound indicates that a condition requiring immediate attention has
occurred.
