NOTE: FAST & WIDE SCSI (Rel 1.8.1)

SCSI was originally developed as a bus that transferred up to 5 Mbytes per second: this bus was 8 bits wide. The transfer rate was doubled to 10 Mbytes per second and the term FAST was introduced. The 8 bit bus was then developed into a 16 bit bus which doubled the transfer rate to 20 Mbytes per second and this development was called WIDE. Hence the term FAST & WIDE SCSI on Shogun.

80 Pin SCSI Drive Technology

The Shogun uses an SCA connector (Single Connector Attachment) on the SCSI disk drive interface. This 80 pin SCA connector includes the 16 bit wide SCSI bus plus the DC power and ID addressing, allowing optimum engineering access for the Shogun HOT PLUG technology.

Using the Front Panel

2 - POWER ON - Press this button to switch the system on from Standby Mode. The Power LED will light up and the system will initiate its boot sequence. Diagnostic codes, expressed as hexadecimal numbers, will appear as a matter of course on the LCD screen on the Front Panel. What happens after this depends on how your Shogun has been configured, i.e. which operating system or other software may be installed.

4 - STANDBY - After you have instructed all network users to close their applications down and log off the network, hold this button down for a specific period of time before the system initiates a shutdown sequence to Standby Mode. The system will display the code 1200 on the LCD and sound a tone. Continue to hold down the STANDBY button until the tone stops, at which time the shutdown sequence begins. In Standby Mode, the mains electricity supply keeps the battery pack fully charged, but there is no DC power supplied to the system.

Press STANDBY and CONTROL simultaneously to cancel the current shutdown sequence.

3 - CONTROL - Press this button to silence alarms and clear LCD display codes that are produced because of internal errors and power failures.

Pressing Control at the end of firmware initialisation forces the system to execute the code of the EPROM instead of the Flash ROM, even if the version in the Flash is newer than that of the EPROM. This still allows you to boot from EPROM if there is something wrong with the Flash code.

5 - RESET - Press this button to initiate a hardware reset, but only if it is absolutely necessary. The LCD will display 1400. You must hold the button down until the accompanying tone stops sounding.

Press RESET and CONTROL simultaneously to cancel the current reset sequence.

Special Button Functions

Pressing Standby, Control and Reset simultaneously while the front drive bay door is unlocked switches the system into a mode in which these three buttons have special functions. The LCD displays 8888 to indicate this mode.

STANDBY or RESET - Pressing one of these buttons initiates a memory dump to the central processing unit by activating and then deactivating the Non-Maskable Interrupt (NMI) signal via the diagnostic processor. You can then use the appropriate function of the network operating system to examine the contents of the dump.

CONTROL - Pressing this button initialises the modem, which is connected to the SMC serial port on the backplane of the Shogun. If the modem initialisation is successful, the LCD displays the code 0000. If the initialisation is unsuccessful, the LCD displays 0F4D or 0F4E.

STANDBY + RESET - Pressing these buttons simultaneously clears the LCD and then releasing them executes an independent Front Panel System Controller (FPSC) reset. This would only be necessary if a major problem or error had occurred in the system.

If you do not press any buttons for ten seconds, the system returns to normal mode.

 

7 - UPS LED

When this LED shows steady green, it means that the system is powered by mains electricity and the batteries are fully charged.

Flashing green means that the system is powered by mains electricity and the batteries are in the process of charging. This will usually be the case after the system has been without mains electricity, i.e. disconnecting the plug or a power failure.

Steady amber indicates that the system is drawing its power off the batteries, i.e. there is no mains electricity. As soon as mains electricity fails, an alarm sounds.

Flashing amber indicates that the battery pack is about to fail.

Off shows that the batteries are disconnected because the isolation switch on the back of the Shogun is in the Off position or the system is disconnected from the mains.

 

8 - POWER LED

Steady green means that the system is on.
Steady amber means that the system has been locked by the infra-red card.
Flashing amber means that the system is detecting data from the infra-red card.
