Installing A7173A Adapter Hardware
This section contains information about installing the A7173A adapter hardware in a supported
HP-UX system.
WARNING! The installation procedures in this section require opening the computer cabinet,
which might expose you to high-energy (high-amperage) circuits and sharp edges on the
equipment chassis. Be sure to remove all rings, watches, and other jewelry before opening the
cabinet.
Before beginning installation, and without removing the adapter from its antistatic bag, inspect
the adapter for any signs of obvious damage, such as chipped or loose components. Contact HP
if the adapter is damaged.
CAUTION: The A7173A adapter contains electronic components that can easily be damaged
by small amounts of static electricity. To avoid damage, follow these guidelines:
• Store the adapter in its antistatic plastic bag until you are ready to install it.
• Work in a static-free area, if possible.
• Handle the adapter by the edges only. Do not touch electronic components or electrical
traces.
• If you must lay the adapter down, place it on a non-conductive mat or surface.
• Use the Electrostatic Discharge (ESD) kit that is provided with the adapter. Follow the
instructions included with the kit.
• Use a suitable ground; for example, an exposed metal surface on the system chassis can
serve as a ground.
Offline Installation
Install the A7173A adapter in any supported HP-UX system according to the offline host bus
adapter installation procedure for that system. For more information about installation procedures,
see the HP system documentation at:
http://docs.hp.com/en/hw.html
NOTE: The A7173A adapter can be installed in any PCI or PCI-X slot, but for best performance,
HP recommends installing the adapter in a PCI-X, 133 MHz, 64 bit, 4x (“Twin Turbo” or “Dual
Rope”) slot. For more information on slot specifications, see the system documentation; or, for
entry-class servers, see the I/O Slot Matrix – Entry Class Integrity Servers, at:
http://docs.hp.com/en/hw.html#General%20Guides
After installing the A7173A adapter, go to “Connecting SCSI Peripheral Devices” (page 17).
Online Installation
The Online Addition and Replacement feature (OLAR for HP-UX 11i v1, or OL* for HP-UX 11i
v2 and later HP-UX releases) enables you to add or replace PCI host bus adapters without shutting
down and rebooting the system, and without adversely affecting other system components. The
system hardware uses slot-specific power control, combined with HP-UX operating system
support, to enable these features.
