Chapter 9: Troubleshooting

Activity indicator stays continually lit without corresponding target device activity, there may

be a problem with the SCSI bus configuration. Verify the SCSI bus configuration.

• Ethernet (10/100)—When lit, these green indicators signify Ethernet link status and activity. If

either of these indicators fail to flicker, or stay continuously lit, there may be a problem with

the network connection or configuration. Verify the network connection and configuration.

The port must be connected to a 10/100BaseT Ethernet network to function properly.

Basic Verification

Serial Port Problems

If you experience trouble communicating with the serial port, verify the configuration of the host

terminal or terminal emulation program. The VT5900-SA requires the baud rate to be set correctly,

8 data bits, 1 stop bit, and no parity. Flow control should be set to none or XON/XOFF, and may

cause problems if set to ‘hardware’. Some terminal programs 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. Be sure the Scroll Lock key on the keyboard of the host computer is

not enabled. If a valid Ethernet IP address is configured, serial configuration settings can also be

set via SNMP and telnet.

In a switched fabric environment, if a login problem is experienced, or if the drives can not be

seen, confirm that the port settings of the VT5900-SA are set for “N-port”.
