Two 10GbE SFP+ ports NM (2 SFP+ & 2 SFP)
Part number: C3KX-NM-10G=
This module has four slots. Two slots support only 1-Gigabit SFP modules, two
slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules.
Note The GLC-T SFP is not supported on the SFP+ slots of C3KX-NM-10G.
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.
