•WS-X6704-10GE

•WS-X6724-SFP

Note Throughout this publication, unless otherwise noted, the term DFC3 daughter card refers to the DFC3A, DFC3B, and DFC3BXL daughter cards.

Caution Some WS-X6748-GE-TX Ethernet modules are equipped with a stiffener bracket that extends across the top of the front row of chips on the module. Alternate procedures are provided in this document that cover the removal and the replacement of the DFC daughter card on modules equipped with the stiffener bracket. You must follow these alternate procedures when upgrading a WS-X6748-GE-TX equipped with a stiffener bracket; otherwise, you can seriously damage the DFC daughter card.
