Note
The general support strategy for the HP 27115A Fiber-Optic Link (HP-FL)
is to replace faulty hardware at the lowest level of assembly authorized for
replacement, known as field replaceable units (FRus).
The HP-FL printed circuit assembly (PCA) is an FRU that may be replaced under
the Hewlett-Packard exchange program for PCAS. See table 4-1.
Before returning a PCA for exchange, remove and save the firmware PROMs.
The exchange assembly
will
be supplied without the PROMs. Contact the HP
Sales and Support Office for details.
Be sure to use anti-ESD precautions when removing or storing the PROMs.
PROMS currently provided with the product are listed in table 4-1. PROM
firmware may be revised by Hewlett-Packard to correct errors, improve
performance, enhance product features, or match operating system, or
application revisions. Should you require replacement of the PROMS, consult
with your Hewlett-Packard representative for the latest PROM version.
Table 4-1 lists FRUs associated with this product.
