Front Panel Description Chapter 1 Product Overview Table 1-3 Network Modules Network Module1 Description 10-Gigabit Ethernet This module has four slots. Two slots support only 1-Gigabit SFP modules, two C3KX-NM-10G 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. 10-Gigabit Ethernet This module has two autonegotiating 10-Gigabit Ethernet (copper) ports.

Description
10-Gigabit Ethernet
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.
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.

This module has two autonegotiating 10-Gigabit Ethernet (copper) ports.
10-Gigabit Ethernet
Service Module
C3KX-SM-10G
This module has two slots that support either 1-Gigabit SFP or 10-Gigabit SFP+
modules.

to-switch encryption between uplinks). For information on configuring the
service module, refer to the
Configuring the Network Services Module
note.
1-Gigabit Ethernet
C3KX-NM-1G
This module has four 1-Gigabit SFP module slots. Any combination of standard
