HP StorageWorks 1000i Virtual Library System - Manual (Page 83)

7 Component replacement
This section describes some of the most common hardware maintenance and servicing procedures
for the VLS1000i.
CAUTION:
The server does not completely power off when the front panel power button is pressed. The power
button toggles server power between On and Standby. In Standby, the server removes power from most
electronics and drives, while portions of the power supply and some internal circuitry remain active. To
completely remove power from the system, see Powering down the VLS .
Safety considerations
To prevent damaging the system, be aware of the precautions you need to follow when setting up the
system or handling parts. A discharge of static electricity from a finger or other conductor may damage
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of
the device.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods to prevent electrostatic damage
There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
Wrist straps are flexible straps with a minimum of 1 megaohm ± 10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug against the skin.
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet
when standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller
install the part. For more information on static electricity, or assistance with product installation, contact
your authorized reseller.
Warnings and cautions
Before removing the node access panel, be sure that you understand the following warnings and cautions.
