4.12Fiber Optic RTM Configuration

For the fiber optic RTM (XCP3240H-RTM-OP-Z)to work correctly, switch firmware

1.2.1.0 or newer is required. The following sections describe support and requirements for configuring the RTM.

4.12.1Module Support

The Fiber Optic RTM was designed to work with any standard compliant SFP or SFP+ module.

4.12.2Backplane Ports Versus RTM Optical Ports

The Sun Netra CP3240 switch’s backplane ports are capable of auto-negotiating between 1G and 10G speeds without any user input. However, the RTM optical ports must be explicitly configured without auto-negotiation for 1G operation. This requirement is due to the underlying technology used in 10G interfaces.

4.12.310G Configuration for RTM Optical Port

For 10G operation, an SFP+ module must be used and the port must be set to no auto-negotiate. For all 10G RTM ports, no auto-negotiateis the default setting.

CODE EXAMPLE 4-6Enabling 10G Operation on RTM Optical Ports

configure interface <0/xx> no auto-negotiate exit

exit

where <0/xx> is the port number of the RTM on Fabric. Valid entries are 0/17, 0/18, 0/19, and 0/20.

For each port on the RTM, enter the command.
