DataDirect Networks EF2800 FC RAID Storage System User Guide (V 1.0)
Troubleshooting and Problem Solving
N
OTE
:
Some terminal emulators do not immediately change to the
new baud rate settings, and you have to exit and restart the emulator to
use the new settings.
Problem: Nothing is displayed on the terminal emulator screen.
The probable cause of this problem is a bad RS-232 cable connection
or swapped transmit/receive lines. If the cable is properly connected
on both ends, try a
null modem adapter that will reverse the RS-232
transmit and receive signals. The need for a null modem adapter
depends on the RS-232 cable you are using.
Problem: The EF2800’s STATUS LED is on, but there is no RS-232
display.
Check that the RS-232 cable is the correct type (straight-through).
Check that the terminal emulation utility on the computer system is
properly configured. See section C.2, "Via the Ethernet Port" on
page 197.
Problem: Screen is updated, but will not respond to keystrokes.
Be sure you are using a straight-through serial cable or try using a null
modem adapter. Disable hardware flow control on the terminal or
terminal emulator. The EF2800 supports Xon/Xoff flow control and
works properly in most cases with no flow control.
Problem: Screen looks correct, but clock is not being updated.
Check to be sure that the EF2800 is still powered on. If you are using
Xon/Xoff, press the <CTRL> key and <Q> key simultaneously to start
data flowing.
Problem: Screen is updated and menus appear correctly, but boxes
around menus look incorrect.
Try a different font in your terminal emulator program, such as
Terminal. If you cannot find a font that looks correct, set ASCII
Display to Yes in the Display options item of the Configuration Menu.
