If an HSC Remote Management card is not installed, there will be no output to the
console screen until selftest completes.
If the ASCII console does not respond to input or does not display any output:
• Make sure that the ASCII console is correctly connected to the server. Refer to
Chapter 2.
• Make sure that the LAN Web Console is NOT connected. If it is, instead of going to
the ASCII console, output will re-directed to the LAN Web Console.
• Make sure the keyboard is correctly connected to the ASCII console.
• Cycle power to the ASCII console.
• Return configuration settings to default by pressing the appropriate soft keys on the
keyboard. Consult the Operator’s Manual for the specific soft keys to press and the
correct sequence. When the correct soft key sequence is entered, the DATACOM
settings will be:
• Make sure REMOTE MODE is ON (asterisk appears in REMOTE MODE block on
the screen) and AUTO Line Feed is OFF (asterisk does NOT appear in AUTO LF
block on the screen)
• Replace the ASCII console with a known good console.
• Try the LAN Web console. If the LAN Web console works but the ASCII console does
not, or neither console works, the system board is the problem. To change the system
board, you must replace the A-Class Exchange Base Unit (EBU). Refer to the
Replacing an A-Class Server Exchange Base Unit (EBU) section.
If you have an HSC Remote Management card installed and the ASCII console works
but the control B function does not, check the position of the SERVICE/NORMAL switch
on the HSC Remote Management card. This switch must be in the SERVICE position to
enable the control B function. If the control B function does not restore, replace the HSC
Remote Management card. Refer to the A-Class Server I/O Card Removal and
Replacement section.
NOTE The control B function is unique to the HSC Remote Management card. If you do not
have an HSC Remote Management card installed, the control B function is not available.
Troubleshooting the Secure Web Console
The Secure Web Console is typically a “dumb” monochrome terminal that can serve as
the communication link between the A-Class server and the system operator, as a
substitute for the ASCII Console. At power on, the server’s selftest software tests server
internal components and external peripherals to determine the operational status of
Baud: 9600 Parity/DataBits: None/8 EnqAck: Yes
Asterisk: OFF Chk Parity: No SR(CH): Lo
