Troubleshooting
When changing any setting on the SNC the configuration must be saved by using either the
saveConfiguration CLI command or through the SNC Manager interface.
saveConfiguration CLI command or through the SNC Manager interface.
Checking the Serial Port
1
Verify you have the correct settings and that your terminal is configured to:
•
Baud rate: 15200
•
Data bits: 8
•
Stop bits: 1
•
Parity: off
•
Flow control: None
2
Verify that your serial cable is less then two meters in length.
Checking the SNC Internal Configuration
Verify that the SCSI devices are mapped properly. Check in the SNC Manager interface or use the
routedisplay iSCSI command to show mappings. If devices do not appear, power down the SNC and
power back on. See

Checking SNC Ethernet Ports
1
Check Ethernet cable integrity. Check the cables for solid connections. Cat5 cable can cause
connection issues with Gigabit Ethernet. Cat6 cable is the best cabling for the SNC.

Verify the IP address, subnet mask, and gateway are properly set on each data port on the SNC for your
network environment. See

3
Verify that the Ethernet speed is set to auto: invoke the get EthernetSpeed all command, check the
Ethernet page of the SNC Manager interface, or check the LED link lights to determine if the Ethernet
speed is correct. Refer to

Determine if the SNC is set to get its IP information from a DHCP server. If so, verify that the DHCP
server has available IP addresses. Refer to

5
Verify that each used Ethernet port on the SNC can be pinged from the desired host. Refer to
If the host cannot ping the SNC ports and the SNC ports are properly configured, continue to the Local
Area Network/Wide Area Network section,
Area Network/Wide Area Network section,
Verify that each port on the SNC can ping each desired host. Refer to
on page 79. If the SNC cannot ping the host, continue to
6
If using DHCP, verify that the DHCP server is assigning the correct IP information to the host.
7
Some older switches/hosts cannot auto negotiate between the SNC and the switch/host at the desired
speed. You could have to force the host/switch or the SNC to the desired speed.

Verify that the host is logging into the SNC correctly by viewing the Connections page and determining
if there a “session open” status.
