HP 27130B
START-UP
To start up and verify correct operation of the l'vfUX, perform the following:
1. Turn on computer system power.
2. A self -test is included on the card. The host computer system determines either if the self -test is
run automatically at power-on or if it must be invoked by the user. Refer to the appropriate
manual for your system for a description of self-test initiation.
a. If the diagnostic test hood is not installed when the self -test executes, the LED located on the
card should light briefly and go out. This indicates that the card passed self -test. If the LED
does not light at all, the card may be defective. If the LED stays on, the card did not pass self-
test. For either of these latter two cases, we recommend that you return the card to
Hewlett-Packard; refer to the next paragraph for reshipment information. If you wish to
repair the card, however, refer to Sections V, VI, and VII for maintenance information, replace-
able parts lists, and schematic logic diagrams, respectively.
b.
If the diagnostic test hood is installed when the self -test executes, the conditions in step l.a.
should occur, plus the LED located on the test hood should light briefly and go out. If the
LEDs (the one mounted on the card and the one on the diagnostic test hood) do not light at all,
or if they light and stay on, the causes are the same as in step 2.a.
3. Refer to your system documentation for information on using the MUX in your system.
RESHIPMENT
If
the MUX is to be shipped to Hewlett-Packard for any reason, attach a tag identifying the owner
and indicating the reason for shipment. Include the part number of the MUX.
Pack the card in the original factory packing material, if available. If the original material is not
available, good commercial packing material should be used. Reliable commercial packing and ship-
ping companies have the facilities and materials to repack the item. BE SURE TO OBSERVE
ANTI-STATIC PRECAUTIONS.
