See the Virtual chassis chapter for information about boot up and configuration of the 7210 SAS-Sx/S 1/10GE operating in standalone-VC mode.
These platforms can operate in the satellite mode or standalone mode, according to the following considerations:
In the satellite mode of operation, these 7210 SAS platforms do not need an assigned IP address because they are managed by the 7750 SR host. The user must connect the correct ports to the 7750 SR host and power on the node. The node automatically fetches the BOF, the image, and the configuration required to operate in satellite mode.
See System boot options for 7210 SAS-Mxp, 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Sx 10/100GE in satellite mode for a detailed procedure used to boot these 7210 SAS platforms.
In the standalone mode of operation, these 7210 SAS platforms provide IP/MPLS functionality. The platforms need an assigned IP address and can be managed independently. See System boot options for 7210 SAS-Mxp, 7210 SAS-S 1/10GE, 7210 SAS-Sx 1/10GE, and 7210 SAS-Sx 10/100GE in standalone mode for procedures to boot these 7210 SAS platforms.
The operating mode that the 7210 SAS platform or node uses to boot up is determined by the chassis-role and host-type BOF parameters. Nokia recommends configuring similar values for both parameters to ensure that the node boots up in the correct mode. Failure to do so will result in an error and the node will not boot up. See BOF chassis-role and host-type parameters for 7210 SAS-Mxp, 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Sx 10/100GE for more information about BOF parameter settings to boot up the nodes in standalone mode and satellite mode.
Nokia recommends using the external SD card slot (cf2:\) on the 7210 SAS-Sx/S 1/10GE and 7210 SAS-Sx 10/100GE or the external compact flash (cf2:\) on the 7210 SAS-Mxp to boot up the node the first time.
To change the chassis role and the mode in which the platform will boot up, manually interrupt the boot process and use the BOF menu option to configure the chassis-role parameter value. You can also revert the parameter value to the factory default setting of factory-default.
To boot up in standalone mode, it is not required to update the BOF to include the host-type parameter. To maintain backward compatibility, the node boots up in standalone mode if the chassis-role parameter is set to factory-default (the value set when it is shipped from the factory), and the host-type parameter is set to none.
The following sections describe the system initialization process for 7210 SAS-Mxp, 7210 SAS-S 1/10GE, 7210 SAS-Sx 1/10GE, and 7210 SAS-Sx 10/100GE in both standalone mode and satellite mode, and the role of the chassis-role and host-type BOF parameters:
