D ESCRIPCIÓN DE LAS CLASES

Operate this unit only when all board covers and frame panels are securely in place. The covers are required for safe operation, good system performance and cooling purposes.

When power is applied to the LOGIQt 700, the Master Controller (MC) initializes the software and hardware and makes some basic checks on the health of the unit. (See Table 4–1.) Boot–up status is reported through the softkey display.

The status messages on the softkey display are in English. For non–English speaking sites, the system can be programmed to display from one to five asterisks to indicate boot–up status. The last item listed is either ‘^*****’ or the software version. To toggle between English and asterisks, hold down [Code + Shift â ] and press the [V] key.

To view the software information at any time after bootup, hold down: [Code + Shift â + X + C

]

Boot–up status messages can be observed on an external computer through the SERVICE port on the bulkhead on the rear of the unit. An external computer can also be connected to the unit through the DB9 connector on the edge of the MC if the PIA is pulled.

POWER–ON/BOOT–UP TESTS

Power Up Tests Description Run Time (sec)

Master Controller The MC initializes its DRAM and loads its boot code. 5 SCSI bus The MC checks that the SCSI drives [the hard drive and the

magneto optical drive (MOD)], are present and accessible.

The MC also tests the hard drive and attempts to repair any problems.

20

VMEbus Board locate

Runs system configuration check to see whether all boards are present and in their correct slot. The MC writes to each board and compares what it reads with the board’s slot number. This test is a basic check of the VMEbus and BE to FE communication.

30

System init Resets then sets up hardware according to presets, defaults, power–down state. Checks and downloads code to the Scan Sequencer DSP, Doppler Processor Master and Slave DSPs, TLM graphics processor (GSP), and OPI/CPU processor. This step initializes all software tasks and configures the

peripherals.

30

Power supplies Checks Front End and Back End power signals. The supplies are synced with the system clock.

10 Probe data The system downloads beamforming data to the TD boards

for the active probe.

CAUTION

4–2–2 Using Magneto Optical Drive (MOD)

1 . Before installing an MOD disk in the MOD, check the disk for loose hardware or damaged labels which would jam inside the MOD. Also ensure that the slide switch in one corner of the disk is set so that the disk is write enabled (disk hole open).

2 . nsert the disk into the MOD with the label facing to the right.

Never move the unit with a disk in the MOD because the drive actuator will not be locked and the MOD could break. Avoid mechanical ejection

(method 3.d below) which leaves the actuator unlocked and the MOD susceptible to damage if moved. If forced to use method 3.d, reboot the system, insert and eject a known good diskette using one of the other methods.

3 . The are a number of methods to eject a disk from the MOD. Ejection is automatic in some cases. Manual ejection methods, listed in preferred order of use, are:

a . Use the softkey choice under Archive Menu –or– click Image Presets up then click the left softkey switch up for ARCHIVE, then toggle the switch under EJECT MOD.

b . Press EJECT button on the MOD while system is ON.

c . Hold EJECT button while the system is booting.

d . Insert the end of a paper clip into the hole next to the EJECT button while system power is OFF.

4–2–3 Archiving and Loading Presets

Note

Always save presets before any software reload. This action is necessary to ensure that the presets locaded after the software reload are as up–to–date as possible.

With system software versions R6 and later, all user presets except changes to English language defaults for the OB comments, can be saved on an MOD disk for reloading on the system. Only seconds are needed to save or load Presets in this manner.

Presets can be saved on the same MOD disk as images. But presets and images are best kept on separate MOD disks because the Archive Menu lists the images but not the presets stored on an MOD disk.

1 . To archive Presets on an MOD disk:

a . Obtain a blank disk or a disk to be recycled. Check the disk to insure that there is no loose hardware or labels. Set the slide switch to write enable (open the hole) on the MOD disk. Then insert the MOD disk into the MOD.

b . Click the Image Presets toggle switch up. The Modify softmenu appears.

c . Click the ARCHIVE softkey up. The Archive Presets softmenu appears.

CAUTION

4–2–3 Archiving and Loading Presets (Continued) Note

The R6.2 and later versions of the system software allow formatting an MOD disk containing L700 System Software. BE CAREFUL TO AVOID REFORMATTING A DISK WITH SOFTWARE THAT IS STILL NEEDED.

Note

To format the MOD disk, click the ARCHIVE FORMAT softkey up. The Archive Format softmenu appears. Then click the FORMAT YES softkey up. (At least one probe has to be attached in order for this to work.) The system reformats the disk in the MOD.

d . To save the user presets, click the SAVE TO MOD softkey up. The Save User Presets softmenu appears.

Click the SAVE YES softkey up. The system saves all user presets, except changes to the English language defaults for the OB comments.

Archive Menu

ILLUSTRATION 4–1

e . When the presets are loaded onto the MOD disk, the Archive Presets softmenu reappears. Click the EJECT MOD softkey up. Label the MOD disk to indicate that fact the disk contains presets and include the date, console serial number, software revision and site name.

2 . To load presets from an MOD to the system:

Note

Presets from a system with R6.x software are not useable in a system with R7.x software.

a . Check the MOD disk containing the presets to insure that there is no loose hardware or labels. Then insert the MOD disk into the MOD.

b . Click the Image Presets toggle switch up. The Modify softmenu appears.

c . Click the ARCHIVE softkey up. The Archive Presets softmenu appears.

d . Click the LOAD FROM MOD softkey up. The system loads the presents from the MOD disk to the sysem.

When the loading is complete, the system reboots and automatically ejects the MOD.
