

To connect and set-up the standard field laptop.

•

To log into the Sequoia system and run diagnostics.

Troubleshooting a Sequoia system which fails to boot to imaging and which won’t allow the Acuson Help Desk to invoke diagnostics is a difficult situation. When the field laptop is connected a “back door” into the system is opened. The laptop can verify the boot sequence, control processes, or run diagnostics. When nothing is seen on the monitor, the laptop is an invaluable troubleshooting aid. Use the laptop to run diagnostics to view logs if: •

The system fails to boot.

•

There is no display on the monitor.

•

To grab a log or data for investigation.

1

Read this module and note the kind of cable needed and the communications protocol.

2

Connect the laptop to the Sequoia system and call up the HYPER TERMINAL program.

3

Set the communications protocol so that it matches the one listed in the following pages of this module.

4

Connect with the system and press on the laptop to establish communications. The UNIX prompt should be on the Hyper Terminal window.

CONNECTING THE LAPTOP HARDWARE CONNECTIONS

A serial port is provided on the PIC board. It is accessed by opening the rear door of the Sequoia system and connecting a RS-232 serial cable to connector Serial/0 RS-232. This connector is a standard 25 pin “D” connector. Figure 14-1 illustrates connecting a laptop to the Sequoia system. Sequoia uses a two-wire connection. That is, only pins 2 and 3 are used for signals. Pin 7 is used for ground. Handshaking is software controlled.

CABLE

The laptop and the Sequoia system are both DTE (Data Terminal Equipment). Therefore, a “Null Modem Adapter,” or a specially wired DTE - DTE serial cable, is required. This cable is now available from Service Materials as P/N 51031.

Setting Reflection Options

FUNCTION KEYS SETUP

Customize the Reflection program to use the function keys to access Sequoia diagnostics. 

To customize Reflection 1 Launch the file made during Basic Setup. 2

Select FUNCTION KEYS from the Terminal setup menu.

3

Program 8 Function Keys (F1 - F8) with prompts. See Figure 14-4.

4

Any of the keys can be named and assigned a command. •

Example: When Sequoia system asks for a “user name,” normally type rcsg. Assign a function key this task by typing in the Command section of the function key.

5

After programming the function keys, click Apply then OK.

USING THE SEQUOIA TERMINAL VIEWING THE BOOT SEQUENCE

Troubleshooting a Sequoia system which fails to boot to imaging and locks out the Acuson Help Desk so that diagnostics cannot be invoked, can be a difficult situation. However, verify the boot sequence by connecting the laptop to the serial port on the Sequoia system. This can be done without entering a login or password. 

To view the boot sequence 1 Connect the laptop to the Serial/0 RS-232 on the PIC board. 2

Launch the HYPER TERMINAL program on the laptop.

3

Restart the Sequoia system.

4

Observe the boot sequence in the Hyper Terminal window. See Figure 14-5.

SAVING DATA CAPTURING TEXT

The data displayed on the Sequoia terminal can be saved in text format on the laptop. Ensure that the entire session is saved, not part of the data. NOTE:



Always use L for LIST when viewing logs in MSM Tools, since S for START will capture data page by page.

To save a Hyper Terminal session to a file: 1 Select CAPTURE TEXT from the Transfer menu. 2

Type a name that describes the file the text will be saved in. •

3

If no name is assigned to the file, Hyper Terminal will assign a name automatically, e.g., CAPTURE.TXT. See Figure 14-8.

Press START.

Figure 14-8 Text Capture window

SENDING E-MAIL TO ACUSON HELP DESK

The preferred way to send the captured file to the Acuson Help Desk is via e-mail. Attach the captured file to the e-mail message and send it to the appropriate Acuson Help Desk.

DELETING HISTORICAL TEXT

It is very important to delete any historical text on the Sequoia terminal before capturing the latest data. Failure to do so may result in the capture of a large amount of data which may not be relevant to the problem.
