Verify the Link
Operation
WARNING
You should verify operation of the PCA and the HP-FL subsystem before
transmitting any data across the link.
To verify operation of the HP-FL link, observe the results of the PCA self-test on
the six LEOs on the front of the PCA. Figure 2-6 shows their locations.
Operation of the computer with the
CIO
card cage open exposes
personnel to hazardous electrical power.
For some systems, a safety interlock switches off the computer power
when the card cage is open. Any attempt to defeat the interlock may
also expose personnel to mechanical dangers.
Caution
The HP-FL PCA does not comply with mandatory electromagnetic radiation and
interference (EMI and
RFI)
regulations when the card cage is open.
PCA Self-Test
The PCA self-test runs whenever the computer power is switched on or the
computer is reset. If you are familiar with the operating system, you can reset
the PCA programmatically. Some sections of the diagnostic program HPFLOIAG
also reset the PCA. (See chapter 3,
Troubleshooting and Diagnostics.)
PCA Self-Test Results
Your system may display the PCA self-test results in any of these ways:
2-8 Installation and Configuration
• The System Status Display identifies any non-operational PCA in the
host backplane. During the SPU self-test, general
I/O self-tests also run.
The host reports this information through the system status display (on
a hexadecimal readout, on the system console, or by the system status
LEOS). Refer to the hardware support manuals for your computer.
• HPFLDIAG displays its results on the system console or a user terminal.
• Most PCAs (including the HP-FL PCA) have LEOs that return the results
of the PCA self-test. The LEDs on the HP-FL PCA are shown below.
