Login Through a Serial Port Fails Due to Inconsistent Serial Port Rates

Publication Date:  2013-05-23 Views:  160 Downloads:  0
Issue Description
After a maintenance terminal is connected to a serial port of a storage device by using a serial cable, the serial port outputs garbled characters and no login information is displayed. After the serial cable is replaced, the maintenance terminal still outputs garbled characters.
Product and version information:
  • S2600
  • S5000 series
  • The operating system running Windows 2003.
Alarm Information
Handling Process
Step 1 On the maintenance terminal, stop the running serial port management program.
Step 2 Restart the serial port management program on the maintenance terminal.
Step 3 Set values of properties including the baud rate, data bit, parity, and stop bit.
Correct settings of the serial port management program are:
 Baud rate: 115,200 bit/s
 Data bit: 8
 Parity: none
 Stop bit: 1
Step 4 After the configuration completes, perform the login again.
Root Cause
The inconsistent serial port rates cause a login failure through the serial port.
Check whether the serial port settings are correct when you manage a storage device through a serial port of a maintenance terminal.
