Hi there,
From the install guide:
SFP+ Port (if present)—The small form-factor pluggable plus (SFP+) are
connection points for modules so that the switch can link to other switches.
These ports are also commonly referred to as mini 10GigaBit Interface
Converter ports. The term SFP+ will be used in this guide.
• The SFP+ ports are compatible with Cisco modules MGBSX1, MGBLH1,
MGBT1, MGBLX1, MGBBX1, as well as other brands of modules.
• The Cisco SFP+ 10G optical modules that are supported in the Cisco
switches are: SFP-10G-SR, and SFP-10G-LR.
• The Cisco SFP+ Copper Cable modules for stacking that are supported
in the Cisco switches are: SFP-H10GB-CU1M, SFP-H10GB-CU3M, and
SFP-H10GB-CU5M.

So long as you are using >2.3.x firmware you should be OK.
cheers,
Seb.
