PCI 10/100Base-TX/3000 Quick
Installation
1
There are two options available for connecting the PCI-based HP e3000
system to a 10/100Base-T LAN: the RJ-45 LAN connection port on the
Core I/O card (included with the base system hardware), or the PCI
10/100Base-TX add-on adapter card (A5230A) for the HP e3000. Both
cards support 10Mbits/s and 100Mbits/s Fast Ethernet operation as
well as full and half-duplex modes. Ensure that the speed, duplex, and
autonegotiation settings of the associated data hub or switch match the
settings on the card (as configured in the network configuration file,
NMCONFIG.PUB.SYS). Refer to the sections on “Notes on Manual Speed
and Duplex Mode Configuration” and “Notes on Autonegotiation and
Autosensing” in this guide for background information on determining
these settings, if needed. For a detailed description of using NMMGR to
configure the 10/100Base-TX link in your NMCONFIG file, see the
NS 3000/iX NMMGR Screens Reference Manual and the HP e3000
Network Planning and Configuration Guide.
1. Verify the PCI 10/100Base-TX software is present in the installed
version of MPE/iX (must be 7.0 or later).
• Make sure MPE/iX 7.0 or later has been successfully installed on
the system. The PCI 10/100Base-TX software license is included
with the FOS (Fundamental Operating System). No additional
software installation is required.
• Run the NMMAINT,78 command and verify complete version
information is displayed for the PCI 100Base-TX link software
(subsystem 78).

PCI 10/100Base-TX/3000 Quick Installation
2. Prepare system for hardware installation and access the system card
bay:
• Login with appropriate system management capabilities and
prepare system for shutdown (e.g., terminate any active jobs or
sessions, etc.)
• Issue a <ctrl-a> shutdown. Make sure the system is halted before
continuing.
• When the system has shutdown completely, power off the system
by pressing the system off button. Unplug the system.
If you are using the Core I/O card LAN connection port instead of an
add-on adapter card, proceed to step 4.
• Open the system to gain access to the PCI backplane, if
applicable.
• Select an empty PCI slot and remove the slot cover (if present).
3. Install the PCI 10/100Base-TX card:
• Observe antistatic precautions.
• Record the serial number from the card, if present.
• Grasp the card by its edges or faceplate with both hands, insert
the card into the slot, and press the card firmly into place.
• Secure the card and retaining screws (if present). Reassemble the
system.
4. Attach the system to the network:
• Attach the 8-pin (RJ-45) plug on a twisted-pair LAN cable into
the RJ-45 connector on the card. The same RJ-45 connector is
used for either 10 or 100Mbit/s operation.
• Attach the free end of the cable to an unused port on the
appropriate hub or switch (or into a wall jack that is connected to
a hub or switch). Connect power to system. Set the hub or switch
speed and duplex mode. The PCI 10/100Base-TX card and the
Core I/O card LAN connection port operate in either full-duplex
or half-duplex mode.
• Power up the system.
• Bring up the MPE/iX operating system.
5. Configure the link using NMMGR:
• Run NMMGR and open the network configuration file (e.g.,
NMCONFIG.PUB.SYS).

• Using “NS Guided Configuration”, configure or update the LAN
Configuration. Change an existing, or add a new type LAN
Network Interface (NI) so that the NI has a link type of BT100.
Enter the Physical path of the LANIC so that it references the
path of the newly installed 10/100Base-T card, or the Core I/O
card LAN port.
NOTE
The Core I/O card will usually have a path of 0/0/0/0; the path should
be printed on the bulkhead near the RJ-45 port.
• On the 100Base-T “link configuration” screen, fill in the
appropriate autonegotiation, speed, and duplex settings. (For
more detailed information on the various screens, see the
NS 3000/iX NMMGR Screens Reference Manual and the
HP e3000/iX Network Planning and Configuration Guide.
• If DTS is required for the link, use the “DTS” screen to configure
the link name, specifying BT100 as link type, and the appropriate
I/O path. The link name and path can be the same as used with
the NS.
• Perform configuration verification and exit NMMGR.
6. Verify the installation:
• Verify that the link starts successfully by starting a network
subsystem (e.g., NETCONTROL START; NET=LAN1) that uses the
newly configured link.
• Check console messages to verify that the link connected
successfully. The link status can also be checked via the
LINKCONTROL command. The following is a sample output for a
successfully connected link:
:linkcontrol lanlink;status=L
Linkname: LANLINK
Linktype: PCI 100BT
Linkstate: CONNECTED
where “LANLINK” is the link name as configured in NMCONFIG
on the “link configuration” data screen, and in this example, is
the link name that was chosen for the NI named LAN1.
• Verify that the card’s Link LED is on. Note that the LED cannot
light unless the link software is also started.
• Verify connectivity with a remote system, e.g., by issuing a “ping”
command via the NETTOOL or PING utilities, or by establishing
a remote VT session (after issuing an NSCONTROL START).
If the link could not be brought up and the remote connection
successfully verified, refer to the section on “Quick Troubleshooting
Tips”.

Notes on Manual Speed and Duplex Mode Configuration
Notes on Manual Speed and Duplex Mode
Configuration
Ensure that the speed, duplex mode, and autonegotiation of the
associated switch are configured the same as in the NMMGR
configuration for the PCI 10/100Base-TX card. If the switch supports
autonegotiation on the ports connected to the cards, this should be
enabled as explained in “Notes on Autonegotiation and Autosensing.”
The NMMGR default is autonegotiation, so if the switch does not
support it, you will need to change settings before using the link.
NOTE
Operation of a link under mismatched host/hub port setting conditions
may result in poor throughput, disconnects and/or application errors.
Because the PCI 10/100Base-TX LAN card and Core I/O card LAN port
support autonegotiation, you should not normally need to manually set
the duplex mode when connected to a switch port which is also enabled
for autonegotiation. Sometimes you may need to manually set the
duplex mode of the card — for example, if the switch is operating at full
duplex but does not autonegotiate.
Full-duplex mode is most commonly found in switches rather than
hubs. It may be found in either 10 Mbit/s or 100Mbit/s switch devices.
Full-duplex mode may provide a throughput advantage under some
circumstances, but the degree of the advantage is applicationdependent.
To manually set the duplex mode of the PCI card, refer to the link
configuration screen in the active NMCONFIG network configuration
file, using NMMGR to access the configuration data and make changes.
The PCI 10/100Base-TX card and the Core I/O card LAN port support
both half- and full-duplex operation.

Notes on Autonegotiation and Autosensing
Notes on Autonegotiation and Autosensing
The PCI 10/100Base-TX/3000 product provides the means for
interfacing various types of HP e3000 systems to either a 10Base-T or
100Base-TX network. 100Base-TX is a subset of 100Base-T networking
defined by the IEEE 802.3u-1995 standard. 100Base-TX provides 100
Mbits/s data transmission over category 5 unshielded twisted-pair
(UTP) cable for which two pairs of wires in the cable are used — one
wire pair for receiving data, and one wire pair for transmitting data.
The same card port that supports 100Base-TX operation can also
support 10Base-T operation (this is true for both the add-on adapter
card and the Core I/O card LAN port).
Autonegotiation is a mechanism defined in the IEEE 802.3u
specification whereby devices sharing a link segment can exchange
information while the link is being established and automatically
configure themselves to operate at the most efficient mode shared
between them.
Autonegotiation is like a rotary switch that automatically switches to
the correct technology such as 10Base-T or 100Base-TX or between
half- and full-duplex modes. Once the most efficient common mode is
determined, autonegotiation passes control of the link to the
appropriate technology, sets the appropriate duplex mode, and then
becomes transparent until the link is broken.
The following is the IEEE 802.3u-defined autonegotiation hierarchy for
resolving multiple common abilities for a 10/100Base-TX card:
• 100Base-TX full-duplex (most efficient)
• 100Base-TX half-duplex
• 10Base-T full-duplex
• 10Base-T half-duplex (least efficient)
For example, if both devices on the link support 10Base-T (half-duplex)
and 100Base-TX (half-duplex), autonegotiation at both ends will select
100Base-TX (half-duplex) instead of 10Base-T (half-duplex).
Many 100Base-TX devices on the market today such as hubs and
switches do not support autonegotiation. Either the speed and duplex
mode of the device are fixed (as is usually the case with hubs), or they
are often manually configured at the desired speed and duplex (as is
often the case for switches). However, switches that support
autonegotiation are becoming more commonplace
If the PCI 10/100Base-TX/3000 card or the Core I/O card LAN port is
connected to a device, such as a switch, that is autonegotiating, the PCI
card will autonegotiate with the device to mutually determine the
highest possible speed and duplex settings between them.

Notes on Autonegotiation and Autosensing
If the PCI 10/100Base-TX/3000 card or the Core I/O card LAN port is
connected to a device that does not support autonegotiation or a device
that has autonegotiation disabled, the PCI card will autosense the
speed of the link and set itself accordingly. The duplex mode of the card
may be set to half-duplex in this case. If you want the card to operate in
full-duplex mode, you must set it using the method described in “Notes
on Manual Speed and Duplex Mode Configuration” in this document.
The PCI 10/100Base-TX card or the Core I/O card LAN port will sense
when the connection between itself and a hub or switch on the other
end of a link has been broken. If a connection is made to another (or the
same) device and autonegotiation is enabled, the autonegotiation and
autosensing process will be done again automatically. Autonegotiation
and autosensing are also done whenever the interface is reset.

Quick Troubleshooting Tips
Quick Troubleshooting Tips
Problem:
Incomplete version information displayed when
:NMMAINT,78 command is issued.
This indicates that the FOS software installation or update (must be
running on MPE/iX 7.0 or later) has not completed successfully. Consult
your HP software support representative.
Problem:
When an attempt is made to bring up the link (e.g., via
a :NETCONTROL START command for a LAN using that
link), it does not connect successfully. Connection
failure messages are logged to the console or a
:LINKCONTROL linkname;STATUS=L command
shows the link as “DISCONNECTED”.
This often suggests an incompatibility between the card’s speed and
duplex settings and the switch or hub settings. Make sure to review the
settings for autonegotiation, speed and duplex in the link configuration
data and make sure they are consistent with what the hub or switch
expects and supports. Bring the LAN down (:NETCONTROL STOP or
:DTCCNTRL option 4) and back up again, to cause software to read the
new configuration. If you still cannot connect successfully, make sure all
the cables are securely connected between the card and the hub/switch
and that the card is properly seated. If that fails, consult your HP
support representative.
