Installing SFP and SFP+ Modules

Before You Begin

You must have an installed network module to use SFP and SFP+ modules (except for the Catalyst

WS-C3850-12S and WS-C3850-24S). The downlink ports on the Catalyst WS-C3850-12S and WS-C3850-24S

switch models support standard SFP modules, and the downlink ports on the Catalyst WS-C3850-12XS and

WS-C3850-24XS switch models support standard SFP+ modules.

See the switch release notes on Cisco.com for the list of supported SFP and SFP+ modules. Use only supported

SFP modules on the switch. For the latest information about supported SFP and SFP+ modules, refer to the

Cisco Transceiver Modules Compatibility Information at

ps5455/products_device_support_tables_list.html

For information about installing, removing, cabling, and troubleshooting SFP modules, see the module

documentation that shipped with your device.

Observe these precautions:

The C3850-NM-8-10G module is held secure in the switch by only one jackscrew. This screw also

helps to eject the module from its connector interface. Before the module can be removed completely,

the screw must be unscrewed all the way out. When removing the screw, a spring pushes the module

out when the screw is completely disengaged. Ensure that you hold the module securely until it is

completely removed.

This will prevent the ports from going into error disabled mode. Similarly, when you remove an SFP

from a port, wait for 5 seconds before reinserting it.
