Upgrading an 8-Slot

Chassis

Before you upgrade the software image of an 8-slot Switch 7700, there are several

things to remember:

■ A Fabric from a 7-slot chassis should be installed in Slot0 in an 8-slot chassis

and must be upgraded to V3.0 (8-slot version) of the software.

■ After you install the redundant Fabric module, you must wait for a few minutes

until a CLI message indicates that the secondary Fabric is ready, then save the

configuration.

■ Use the management port on the Fabric to download code.

■ You must set the boot-loader file to the V3.0 file after you download it.

■ After you upgrade both Fabrics, you must reboot the switch.
