Safety Instructions
Always use caution when servicing any electrical component. Before handling the Magma Expansion chassis, read the
following instructions and safety guidelines to prevent damage to the product and to ensure your own personal
safety. Refer to the “Advisories” section for advisory conventions used in this manual, including the distinction
between Danger, Warning, Caution, Important, and Note.
§ Always use caution when handling/operating the computer. Only qualified, experienced, authorized
electronics personnel should access the interior of the computer and expansion chassis.
WARNING
Never modify or remove the radio frequency interference shielding from your workstation or
expansion unit. To do so may cause your installation to produce emissions that could interfere with
other electronic equipment in the area of your system.
When Working Inside a Computer
1. Before taking covers off a computer, perform the following steps:
2. Turn off the computer and any peripheral devices.
3. Disconnect the computer and peripheral power cords from their AC outlets or inlets in order to prevent
electric shock or system board damage.
In addition, take note of these safety guidelines when appropriate:
§ To help avoid possible damage to systems boards, wait five seconds after turning off the computer before
removing a component, removing a system board, or disconnecting a peripheral device from the computer.
§ When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some
cables have a connector with locking tabs. If you are disconnecting this type of cable, press in on the
locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid
bending any connector pins. Also, before connecting a cable, make sure both connectors are correctly
oriented and aligned.
CAUTION
Do not attempt to service the system yourself except as explained in this manual. Follow installation
instructions closely.
