standard SFP modules are supported. SFP+ modules are not supported.
If you insert an SFP+ module in the 1-Gigabit network module, the SFP+
module does not operate, and the switch logs an error message.

• Two slots (left side) support only 1-Gigabit SFP modules and two
slots (right side) support either 1-Gigabit SFP or 10-Gigabit SFP
modules.
• Three slots (left side) support 1-Gigabit SFP modules and one slot
(right side) supports 10-Gigabit Ethernet SFP+.
Supported combinations of SFP and SFP+ modules:
• Slots 1, 2, 3, and 4 populated with 1-Gigabit SFP modules.
• Slots 1 and 2 populated with 1-Gigabit SFP modules, and Slot 4
populated with one 10-Gigabit SFP+ module.
