4.0 Configuration, Installation, and Operation
4.1 Handling and static-discharge precautions
After unpacking, and before installation, the module may be exposed to potential handling
and electrostatic discharge (ESD) hazards. Observe the following standard handling and
static-discharge precautions:
Caution -
• Be sure you are properly grounded before handling the module. Put on a grounded wrist
strap, or ground yourself frequently by touching the metal chassis of a computer that is
plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire
installation procedure.
• Handle the module by its edges or front panel only.
• Always rest the module on a padded, antistatic surface until you mount it in the enclosure.
• Do not touch the connector pins or any components on the printed circuit board.

Considerations For Installation
VMEbus Slot Requirements
The VS1-250 requires one slot in a standard VMEbus 6U card cage. Many drives have a
steel cover, which could potentially cause a shorting problem. If you are going to have a
VMEbus card located in the next adjacent slot, carefully check it to make sure that no leads
are likely to touch the top of the drives mounted on the VS1-250 module.
VMEbus Backplane Configuration
The VMEbus P1 connector supplies all operating power to the VS1-250 as well as ground.
No other signals are connected to the modules P1 connector. When configured for SAS to
VME backplane the SAS bus is connected via the P2 connector (see Table 2 for pin-outs).
Power Supply Requirements
Make sure that your VMEbus power supply has adequate capabilities to support the
operation of the drives mounted on the VS1-250 module while considering all other cards in
your VMEbus system. The specifications listed in Chapter 5 should be consulted for the
maximum current requirements. Your power supply must be capable of providing sufficient
current for the drive during initial operation.
