Cisco Cat 3K-X 10G Network Module

CISCO Cisco Cat 3K-X 10GNetwork Module


10-Gigabit Ethernet C3KX-NM-10G

The 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 with 1-Gigabit SFP modules
• Slots 1 and 2 with 1-Gigabit SFP modules and Slot 4 with one 10-Gigabit SFP+ module
• Slot 2 with one 10-Gigabit SFP+ module and Slots 3 and 4 with 1-Gigabit SFP modules
• Slot 2 and Slot 4 each 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 turns on. The SFP module in Slot 1 does not work as long as an SFP+ module is in Slot 2, whether it has link up or not. The same precedence applies to Slots 3 and 4.
