U522 4-Port Ethernet PCI Card  
U522 4-Port Ethernet PCI Card  
The U522 PCI card is a high-performance 4-Port Ethernet adapter that enables you to  
connect a DNCP Series 400/400-CO system to a local area network (LAN). The U522  
PCI card is based on a 32-bit bus architecture that optimizes data flow between the  
system and the network, resulting in the highest possible throughput with low CPU  
utilization.  
and 100-Mbps Fast Ethernet communication. The card automatically senses the speed  
of the port to which it is attached, and configures itself accordingly.  
Each DNCP Series 400/400-CO system can support up to four U522 PCI cards (16  
LAN ports). These cards can be paired, using the Redundant Network Interface (RNI),  
to provide backup fail-over protection. Figure 1-1 shows the U522 PCI card.

Handling PCI Cards  
Handling PCI Cards  
PCI cards are extremely sensitive to electrostatic discharge. To avoid damaging a PCI  
card during handling, take the following precautions.  
C A U T I O N  
Do not walk around carrying a PCI card that is not in its  
static-protective envelope, as it can damage the card.  
Always store the PCI card in its static-protective envelope if it is not installed  
in the system.  
Always hold a PCI card by its edges.  
Always ground yourself before handling a PCI card. To ground yourself, touch  
the inside of the PCI card cage to discharge any static electricity, or wear a  
grounding strap. If you have a grounding strap, attach one end to the rear of  
the system, and place the other around your wrist (Figure 1-4).

Software Requirements  
Software Requirements  
For operating systems prior to HP-UX version 11.00.61, the U522 card may require that  
software patches be installed on the operating system. See the DNCP Patches for  
U522, U405, U406, D843, and D844 (R300066) document for the HP-UX operating  
systems and software patches needed to support the U522 PCI card on the DNCP  
platform.  
Also, the required Ethernet communications software must be installed before you can  
use the U522 card. For information about installing and configuring the  
communications software to be used with the U522 card, refer to the following:  
HP-UX Operating System: LAN Configuration Guide (MAN0005)  
HP-UX Operating System: Redundant Network Interface (MAN0006)  
C A U T I O N  
Do not use the RNI to pair two cards in the same card  
cage. If you pair two cards in the same card cage, loss of  
power to that card cage (including opening the card cage  
door) will terminate the network link.  
C A U T I O N  
Do not use the RNI to pair two LAN ports on a single U522  
PCI card.

Installing a U522 PCI Card  
After installing the U522 card in the PCI card cage, you must connect the UTP cables  
to the card and, if necessary, configure the card.  
1. Connect the UTP cables to the card connectors on the top of the PCI card cage  
(Figure 2-4).  
2. Close the card cage door. When you close the door, power is restored to the card  
cage.  
3. If you replaced a U522 card that had been previously installed in the same slot, the  
card performs a self-test, during which the yellow status light on the card cage is  
illuminated. The yellow light then flashes while the system configures the card.  
When the card is online, both the green and the yellow lights are illuminated,  
indicating the card is running simplexed.  
If this is a first-time installation, the red status light is illuminated, indicating that you  
must install the communications software and configure it for use with the U522  
card. Refer to the appropriate manual from those listed in the ‘‘Software  
Requirements’’ in Chapter 1 for information on these procedures.

Troubleshooting  
3-  
DNCP Solutions maintenance software continuously monitors the function of PCI  
cards. If a PCI card malfunctions, the system determines the severity of the problem.  
If a malfunction is transient, the PCI card restarts automatically. If a malfunction is  
permanent, the system takes the card out of service and the red status light on the PCI  
card cage is illuminated.  
In addition, the system records all PCI malfunctions in the online system error log files  
and displays corresponding error messages on the system console. HP-UX error log  
files use the path name /var/adm/syslog/syslog.log  
Getting Help  
DNCP Solutions systems offer a unique failure-reporting and remote diagnosis feature  
known as the Remote Service Network (RSN). If the RSN is connected to your system,  
it automatically reports all part failures to the DNCP Solutions Customer Assistance  
Center (CAC), which then notifies you of the problem and diagnoses its cause. (If you  
are serviced by a distributor, the remote diagnosis and service process may vary.) If  
the problem is caused by a failed PCI card, the CAC provides you with a replacement  
procedure.  
You may contact the DNCP Solutions Customer Assistance Center (CAC), 24 hours a  
day, 7 days a week by calling one of the phone numbers listed below.

Getting Help  
DNCP Solutions does not expect you to diagnose complex problems or perform major  
repairs. However, in some cases you may be able to solve a problem without replacing  
the card or contacting the CAC. When a status light or console message suggests that  
either a U522 PCI card has failed or there is a network problem, follow these steps.  
1. Check the syslog.log file, which may provide more detailed information about  
the problem.

Interpreting the PCI Card Status Lights  
Each PCI card has three status lights that are arranged in a traffic light configuration  
directly above the card on the PCI card cage. These status lights indicate the current  
condition of the card. Figure 3-1 shows the status lights, and Table 3-1 explains their  
meaning. A status light sticker is attached below the PCI card doors, in the rear of the  
cabinet, for easy reference.
