Functional Verification
The Functional Verification Test for the E1364A switch consists of sending
the
*IDN? command and checking the response. This test can be used at any
time to verify that the switch is connected properly and is responding to
basic commands.
Procedure
1. Verify that the switch is installed in the mainframe and that the
mainframe has passed its power-on test.
2. Send the *IDN? command to the switch module (see example
following).
3. The switch module should return the following string (revision
number may vary):
HEWLETT-PACKARD,SWITCHBOX,0,A.06.00
NOTE If the primary address setting, secondary address setting, or interface select
code is set incorrectly, the switch will not respond. Verify proper address
selection before troubleshooting.
Example An example follows which uses an HP 9000 Series 300 computer with
HP BASIC and a switch address of 70915.
10 DIM A$[80]
20 OUTPUT 70915;"*IDN?" !Send the ID command
30 ENTER 70915;A$ !Get response
40 PRINT A$
50 END
Operation Verification
The procedures in this section are used to provide a high confidence that the
switch module is meeting published specifications. The Operation
Verification tests are a subset of the Performance Verification tests and are
suitable for checkout after performing repairs.
Operation Verification is performed by completing the Closed-Channel
Resistance Test as described in the Performance Verification test
procedures. This test is usually sufficient to verify that the switch module is
meeting its specifications.
