Troubleshooting: Dell PowerVault 35F User's Guide
Verify Host Configuration
In some cases, it may be that the host bus adapter or driver may not be working properly. Check the configuration of
these elements. It may be useful to check the release notes for the driver provided to see if there are any specific issues
or required configuration. It may also be useful to ensure that you are using a current version of the host bus adapter
driver.
Verify HBA Device Driver Information
Check the HBA device driver Readme file for configuration specifics. An HBA may require a different configuration,
depending on whether it is connected to a loop or a switch.
RS-232 Port Problems
If you experience trouble communicating with the RS-232 port, verify the host terminal emulation configuration. The
PowerVault 35F requires the baud rate to be set correctly, 8 data bits, 1 stop bit, and no parity. Flow control should be
disabled, and may cause problems if set to 'hardware' or XON/XOFF. Some hosts may not support baud rates higher
than 19200, so a lower baud rate may be required. If problems persist, you may want to check the cabling or try a
different host. If a valid Ethernet IP address is configured, RS-232 configuration settings can also be set via SNMP
and telnet.
How To Recover If You've Lost or Forgotten Your Password
If you've lost or forgotten your password, simply reset the PowerVault 35F's configuration to factory defaults through
the serial interface. The PowerVault 35F configuration can be reset to factory defaults in one of two ways.

1. Select the Advanced Options menu.
2. Select 1) Perform configuration.

NOTE: Once you select Reset Configuration to Factory Defaults, all previous configuration changes made by
the user will be lost. You will need to change any configuration options, such as baud rate and Ethernet address,
again.
