Dell™ offers several blade and rack-mounted switches that allow users to upgrade the hardware by installing

expansion modules. Thanks to Dell’s FlexIO technology, these modules can be used to increase access ports, augment upstream bandwidth, extend media forms (10GBase-T, SFP+, QSFP+, CX4, XFP), or add stacking capabilities. This document identifies each Dell PowerConnect switch and its corresponding set of expansion modules.

When possible, Dell allows for a module to be used in multiple devices. Customers who have purchased a module for one device can freely move that module to another device when supported.
