Chapter 1 Troubleshooting Overview 1-5
Host-to-array channel failures occur when the connection between the array and the
host is either severed or intermittent. The components that make up this data
channel connection are:
■
Host bus adapter (HBA), which resides on the host
■
Gigabit interface converter (GBIC) adapter, used to connect the FC-AL cable to an
SBus HBA
■
Fibre Channel cable that connects the array to the host
■
Media interface adapter (MIA), which converts the light source from the host to
an electron source for use in the array
■
Channel interface port in the array
Refer to Section 3.7.4, “Testing the Array With StorTools” on page 3-19” and the Sun
StorEdge StorTools User’s Guide for information identifying data channel failures.
1.5 Static Electricity Precautions
Follow these procedures to prevent damaging the FRUs:
■
Remove plastic, vinyl, and foam from the work area.
■
Before handling a FRU, discharge any static electric charge by touching a ground
surface.
■
Wear an antistatic wrist strip.
■
Do not remove a FRU from its antistatic protective bag until you are ready to
install it.
■
When removing a FRU from the array, immediately place it in an antistatic bag
and packaging.
■
Handle a FRU only by its edges and avoid touching the circuitry.
■
Do not slide a FRU over any surface.
■
Limit body movement (which builds up static electricity) during FRU installation.
