FIGURE 4-26 IEEE 1394 Problem
This flowchart can only
be used for Sun sup-
ported devices.
There is a problem with
an IEEE 1394 device inter-
acting with the system.
Is the
suspect device a Sun
supported device?
Obtain the ok prompt.
See “Obtaining the ok
Prompt for Testing” on
page 5-2.
Do you see this text?

Replace the combination
card. See “Replacing the

Determine if the combi-
nation card is recognized.

Disconnect all IEEE 1394
devices and attach the
suspect device directly to
the combination card.
Is the problem
still there?
Problem is with cabling,

In normal operation, the IEEE 1394 ports allow for hot-
plugging of peripherals. If the peripheral is not recog-
nized, try plugging it in to another connector. Do not force
the connection.
Checking a component means checking the electrical con-
nections and fit.
