Configuration Tasks

Overriding the Default Microcode Path

The wireless line card requires external microcode images in order to operate. The Cisco IOS software has a default file path where it looks to find the microcode and the microcode version. For routers that are configured with line cards at the factory, the path and version of the microcode image in flash memory matches the default setting and allows the line card to come up without any additional configuration. However, you may want to override the default microcode path, for example, to upgrade your software to the latest release. Use the following steps to change the path for the microcode.

	Command	Purpose
Step 1
	Router# dir flash	Displays the content of the Flash memory.
Step 2
	Router# show microcode	Displays the default path for the microcode.
Step 3
	Router# config t	Enters the global configuration mode.
Step 4
	Router(config)# microcode cwrhe bundle-path	Specifies the a new path for the headend
		microcode bundle.
Step 5
	Router(config)# end	Exits the global configuration mode and enters the
		EXEC mode.
Step 6
	Router# show microcode	Displays the specified path for the microcode.
Step 7
	Router# microcode reload cwrhe	Loads the microcode onto the line card.
Step 8
	Router# copy running-config startup-config	Saves the path for the microcode so that the
		microcode is loaded from the new path the next
		time the router is rebooted.

Configuring IF Loopback (Optional)

An IF loopback confirms that the hardware is seated properly in the chassis and that the analog and signal processing portions of the wireless modem card are functioning as expected. Loopback does not test forward error corrections (FEC) and MAC-layer interface of the line card; other tests must be done for these portions of the line card. Each receive path must be tested individually when there are two antennas employed.

Use the following commands to execute an IF loopback. Specifying these commands shuts down the radio link and initiates the IF loopback.

	Command	Purpose
Step 1
	Router(config-if)# shut	Stops the interface.
Step 2
	Router(config-if)#loopback local if main 2	Configures the IF to loop the lower half of the
		channel.
Step 3
	Router(config-if)# no shut	Brings up the loopback mode.
Step 4
	Router(config-if)# shut	Stops the interface.
Step 5
	Router(config-if)#loopback local if main 3	Configures the IF to loop the upper half of the
		channel.
Step 6
	Router(config-if)# no shut	Brings up the loopback mode.
Step 7
	Router(config-if)# shut	Stops the interface.
