To Install the HP 16500H Hardware
If you need instructions for removing and replacing parts of the HP 16500B,
refer to the HP 16500B Logic Analysis System Service Guide.
WARNING SHOCK HAZARD Disconnect the power from the mainframe before
performing the following procedures. After disconnecting the power, wait at
least six minutes for the capacitors on the power supply board and the CRT
driver board to discharge before servicing the instrument. Failure to do so
could result in electrical shock. Hazardous voltages exist on the power
supply, the CRT, and the CRT driver board of the HP 16500B mainframe. As
long as the AC LED on the power supply has any illumination, a significant
charge remains on the capacitors.
CAUTION Use grounded wriststraps and mats when performing any service to this
module or to the HP 16500B Logic Analysis System. Electrostatic discharge
can damage electronic components.
For correct orientation of the cables, match the slots on the cable connectors
and on the board connectors.
1Remove power from the HP 16500B mainframe, then remove the
measurement modules, the four rear feet, and the top and bottom
covers of the mainframe.
2Remove the sheetmetal plate on the rear of the mainframe covering
the slot where the interface module will be installed.
With the interface module installed, you will not use the plate. Save the plate
to use in case the interface module is removed.

To Verify the Installation
1Check that "Ethernet" is available in the Communications menu of
the mainframe System Configuration menu.
When you power-up the mainframe, the Logic Analysis System performs the
power-up self-tests. After the self-tests are finished, the screen displays the
System Configuration menu. If the operating system finds an interface
module installed, then Ethernet is available in the Communications menu.
2If "Ethernet" is not available in the Communications menu, go to
"Verifying the Interface Module Performance" in Chapter 3 of this
manual.

Ethernet LAN Interface
The LAN interface provides a network-based interface between the HP
16500B Logic Analysis System and personal computers and workstations over
a 10Base-T Ethernet LAN. Detailed information on installing and
troubleshooting in the LAN environment is covered in the HP 16500H LAN
Administrator’s and Service Guide. The following steps are an overview of
the process with some troubleshooting hints.
1Connect an EtherTwist 10Base-T LAN cable into the RJ-45 LAN port
on the interface module.
If your LAN uses ThinLAN connections, a Media Access Unit (MAU) is
required.
2Set up the configuration menus on the HP 16500B mainframe.
You can configure the interface module to work with your network from the
HP 16500B front-panel touchscreen. After the HP 16500B power-up tests are
complete, the Ethernet configuration can be accessed in the Communications
menu.
The interface module automatically obtains the subnet mask by sending a
broadcast ICMP query over the network. The broadcast ICMP query is
transmitted approximately 10 seconds after power is applied to the interface
module and approximately 2 seconds after the IP address is changed. When
the query is answered by another network device, the interface module
stores the information in internal memory.

3Verify connectivity with an echo request.
In most network environments, an echo request is accomplished using the
ping utility. For the exact syntax for the ping or other echo request utility,
refer to your network documentation. A normal response to multiple echo
requests is 9, 10, or possibly 11 packets transmitted for every 10 echo
requests.
If there is no response to the echo request, first check the command line. If
an IP address is used in the echo request command line, then the IP address
typed in the command line should match the IP address stored in the
HP 16500B Ethernet Configuration menu. If a hostname was used in the
command line, then check the node names database to see that the IP
address and the hostname for the HP 16500B were correctly entered.
After verifying the command line, check to make sure the hardware is
connected and operating properly. To verify operation of the interface
module, refer to "To verify the interface module performance" in Chapter 3.
An intermittent response to the echo request indicates a problem with the
LAN itself. Use a LAN analyzer or LAN management software to monitor
activity and determine where bottlenecks or other problems are occurring.
4Mount the HP 16500B system with an NFS mount.
An NFS mount of the 16500B system depends on the network environment
the system is being mounted to. For UNIX, the mount command with the
computer name and mount point are required. In MS-DOS, a virtual drive
specifier and 16500B IP address are required. File Manager in MS-Windows is
used to mount in an MS-Windows environment. In all cases, either the
16500B file server /control or /data directory must be specified depending on
whether the 16500B system is being mounted for control or data.
The normal response to an NFS mount in most cases is the command line
prompt reappears. If the system includes a utility to view the mount table
(for example, in UNIX, the mount command alone displays /etc/mnttab),
then the 16500B remote file server should appear in the table of mounted
devices.
If error messages appear, then check the command line syntax. If the syntax
is correct, then resolve the error message directly using your network
documentation. Note that an error message appears if you try to mount too
soon after power-up. You need to wait at least 15 seconds after the System
Configuration menu is displayed on the HP 16500B display before attempting
to mount.

HP 16501A Expansion Frame Interface
The interface port for the HP 16501A Expansion Frame permits you to
quickly and easily connect an expansion frame to the HP 16500B mainframe.
With an expansion frame connected to the mainframe, a total of ten
16500-series measurement modules can be configured and utilized. Detailed
service information for the HP 16500B mainframe and 16501A Expansion
frame is covered in the HP 16500B/16501A Service Manual.
The expansion frame is recognized by the mainframe if the "Master Frame"
text on the left side of the mainframe power-up screen appears as a blue
user-select field. If the text does not appear as a blue field, the most likely
cause is a defective interface module.

Servicing the Interface Module

Verify the Interface Module Performance
Before starting the interface module performance verification, check all
cables and connectors to ensure that all cables are properly connected.
The interface module performance verification (self-test) is divided into two
sections. The first section tests the physical connection, for example, the
cable and termination. The second section tests the internal functions of the
LAN IC on the LAN interface module. When both sections of the self-test
have been completed, a status reporting message appears in the Option
Board Test menu. The status reporting message indicates whether the tests
pass, if a failure occurs, and which section failed.
The first section, the physical connection, is tested depending on the LAN
topology used. Because EtherTwist (10Base-T) is used, the interface module
will listen for the heartbeat signal from the LAN. If a heartbeat is received,
then the physical connection is considered good.
The second section is tested using internal loopback features of the LAN IC.
Transmitted packets are looped back to the receive circuit of the LAN IC .
When the looped back packets are received, they are processed like a packet
received from a remote client or server. If the looped back packet is
recognized and processed, then the LAN IC and the LAN function are
considered good.
The Option Board Test also tests the system integrity of the High Speed Port
on the interface module. If an HP 16501A Expandsion Frame is connected,
the Option Board Tests can also be used to test the expansion frame
interface.
