SFP and SFP+ Modules

The switch-Gigabit Ethernet SFP and SFP+ modules provide copper or fiber-optic connections to other
devices. These transceiver modules are field-replaceable, providing the uplink interfaces when installed
in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45
connectors for copper connections.
Use only Cisco SFP modules on the switch.

Description
This module has no uplink ports.
This module has four 1-Gigabit SFP module slots. Any combination of 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.
slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules.
The four slots are grouped as two pairs with each pair consisting of one SFP slot
and one SFP+ slot. Each pair supports either two 1-Gigabit SFP modules or one
10-Gigabit SFP+ module. A 10-Gigabit SFP+ module cannot operate at the same
time as the corresponding 1-Gigabit SFP module in the pair.
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.
Slot 2 populated with one 10-Gigabit SFP+ module and Slots 3 and 4
•
populated with 1-Gigabit SFP modules.
Slot 2 and Slot 4 each populated with 10-Gigabit SFP+ modules.
•
A 10-Gigabit SFP+ module takes precedence over a 1-Gigabit SFP module
except when an SFP module is first inserted in Slot 1 and has link. When you
insert an SFP+ module in Slot 2, the SFP in Slot 1 retains link. The SFP+ module
in Slot 2 does not operate.
When the SFP module in Slot 1 is shutdown, loses link, or is removed, the SFP+
module in Slot 2 becomes operational. At this point, the SFP module in Slot 1
will not become operational under any circumstance for as long as an SFP+
module remains in Slot 2 whether it is link up or not.
The same precedence applies to Slots 3 and 4.
