To insure proper installation of the multiplexer, you should study
this
manual, the computer system reference manual, and the reference and in-
stallation manuals for all of the peripherals you intend to attach to the
MUX.
The interface card supplied with the HP 27140A product is identified by a
part number (27140-60001) and a date code consisting of a letter and four
digits (A-2450) printed below the part number. This information is
printed on a label
affIXed to the card. The label also has two other
alphameric fields. Both are production sequence numbers, and will not
affect you. However, your CE may need to refer to them occcasionally, so
it is a good idea to record all of this
information.
The sticker will look like this:
27140-60001 XX
A-2450 XXXXXX
Above, "X" represents any alphanumeric character. Do not remove the
identification label. If it is missing,
service for your MUX may.be delayed
while the board is identified.
