Using the Serial Interface

Ethernet Configuration

•

•

Select 5 to toggle the Ethernet mode among these options:

10Mbps Only

100Mbps (half duplex) Only 100Mbps (full duplex) Only 10/100Mbps (Auto-Neg.)

Select 6 to change the hostname. This alphanumeric entry is one word up to eight characters long.

Note. Do not use an uppercase Z as a part of the hostname as it is the autobaud hot key used by the Microsoft Windows hyper terminal utility for serial connections.

Select 7 to toggle the DHCP setting. This setting enables and disables support for the Dynamic Host Configuration Protocol. When enabled, the router retrieves a dynamic IP address from a DHCP server located on the Ethernet network that the Fibre Channel to SCSI router is connected to.

Once DHCP is enabled, save the current configuration and reboot the router before an IP address can be requested from the DHCP server:

1.Select X Return to previous menu.

2.Select A Save Configuration.

3.Select X Return to previous menu.

4.Select 4 Reboot.

After the router reboots, the Main menu appears on the serial interface. For Telnet, a new session needs to be opened to continue configuring the router. DHCP status can be verified from the Ethernet Configuration Menu where DHCP Configuration is indicated as Enabled if DHCP has been successfully activated. The IP address might also appear different than the former non-DHCP IP address.

Note. To use the DHCP feature, a DHCP server must be operational on the Ethernet network used by the Fibre Channel to SCSI router. If the DHCP feature is used when there is no DHCP server, the standard for DHCP requires that the router wait three minutes for a response from a DHCP server before timing out.

Your DHCP server might allow you to set up a lease reservation for an IP address by providing the server with the Ethernet MAC address of the Fibre Channel to SCSI router. This sets the DHCP server to always provide the same IP address to the Fibre Channel to SCSI router. This setup can be useful for remote management of the router via Telnet or Crossroads Visual Manager. Because the method of setting up a lease reservation varies depending on the DHCP server being used, you should contact your network administrator for assistance.

•Select 8 to access the SNMP Settings for the Fibre Channel to SCSI router, including the community names for GET and SET as well as SNMP Trap settings. For Trap settings, select the IP address of the device to send the SNMP trap notifications.
