are generally suffi cient 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 mobile rack backplane and/or expander card 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.•
1-2 General Safety Guidelines
Always disconnect power cables before installing or removing any components •
from the computer, including the backplane.
Disconnect the power cable before installing or removing any cables from the
•
backplane.
Make sure that the backplane is securely and properly installed on the mother-
•
board 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 identifi ed with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means
the jumper is off the pins.
