Network Module1

Description

C3850-NM-4-1G

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.

 

 

See Figure 3-1 on page 3-2.

 

 

C3850-NM-2-10G

This module has four slots that support the following combinations:

 

 

• 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.

 

 

• Slot 3 and Slot 4 each populated with 10-Gigabit SFP+ modules.

 

 

See Figure 3-2 on page 3-2.

 

 

C3850-NM-4-10G

This module has four 10-Gigabit slots or four 1-Gigabit slots.

 

 

Note This is only supported on the 48-port models.

 

 

See Figure 3-3 on page 3-3.

 

 

C3850-NM-BLANK

This module has no uplink ports.

 

 

 

1. All network modules are hot-swappable.

For information about the network modules, see the “Installing a Network Module in the Switch” section on page 2-19. For cable specifications, see Appendix B, “Connector and Cable Specifications.”

SFP and SFP+ Modules

The SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These transceiver modules are field-replaceable, and they provide 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 and SFP+ modules on the switch. For the latest information about supported SFP and SFP+ modules, refer to the Cisco Transceiver Modules Compatibility Information at:

http://www.cisco.com/en/US/products/hw/modules/ps5455/products_device_support_tables_list.html

For information about SFP modules, see the SFP module documentation and the “Installing SFP and SFP+ Modules” section on page 3-9. For cable specifications, see Appendix B, “Connector and Cable Specifications.”

The Catalyst 3850 switch supports the SFP module patch cable (CAB-SFP-50CM), a 0.5-meter, copper, passive cable with SFP module connectors at each end. This cable is only used with 1-Gigabit Ethernet SFP ports to connect two Catalyst 3850 switches in a cascaded configuration.
