v
The use of a grounding system is recommended. For example, wear an
electrostatic-discharge wrist strap, if one is available. Always use an
electrostatic-discharge wrist strap or other grounding system when working
inside the server with the power on
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 surface on the outside 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.
Returning a device or component
When returning a device or component, follow all packaging instructions and use
any supplied packaging materials for shipping.
Hard disk drive problems
Use this information to address various hard disk drive issues.
v
Before running a procedure, refer to “Removing a file module to perform a maintenance action” on page 51.
v
Follow the suggested actions for a Symptom in the order in which they are listed in the Action column until
the problem is solved.
v See “Removing and replacing parts” on page 81 to determine which components are customer replaceable
units (CRUs) and which components are field replaceable units (FRUs).
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
