Safety Warnings
This section includes the installation cautions and warnings. Translations of the safety warnings are available
in the Regulatory Compliance and Safety Information for Cisco Catalyst 9300 Series Switches.
Read this section before you install a network module.
Proper ESD protection is required whenever you handle equipment. Installation and maintenance personnel
should be properly grounded by grounding straps to eliminate the risk of ESD damage to the equipment.
Equipment is subject to ESD damage whenever you remove it.
Caution
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement
1030
Warning
Do not reach into a vacant slot or chassis while you install or remove a module. Exposed circuitry could
constitute an energy hazard. Statement 206
Warning
Installing a Network Module
The switch can operate without a network module, but a blank module (with no ports or SFP slots) is available
and should be installed when uplink ports are not required.
Note

Installing a Network Module
Installing a Network Module in the Switch

The switch generates logs when you insert or remove a network module with SFP/SFP+/SFP28/QSFP+ slots.
Note
Use only supported network modules and Cisco pluggable transceivers. Each module has an internal serial
EEPROM that is encoded with security information.
The network module is hot-swappable. If you remove a module, replace it with another network module or
a blank module.
The switch complies with EMC, safety, and thermal specifications when a network module is present. If no
uplink ports are required, install a blank network module.
Note
Before you begin
When installing network modules, observe these precautions:
• Do not remove the blank module from the slot unless you are installing a network module. A module
must be in the uplink slot at all times.
• Do not remove the dust plugs from the pluggable transceivers or the rubber caps from the fiber-optic
cable until you connect the cable. The plugs and caps protect the module ports and cables from
contamination and ambient light.
•Removing and installing a network module can shorten its useful life. Do not remove and insert a network
module more often than is necessary.
•To prevent ESD damage, follow your normal board and component handling procedures when connecting
cables to the switch and other devices.
Unlike other network modules, the C9300-NM-8X cannot be fully inserted and secured until the jackscrew
is properly tightened.
1. Push the module into the uplink slot until the jackscrew connects with the rightmost tab.
2. You will feel some light resistance, because a spring-loaded tab inside the slot will push back against the
C9300-NM-8X module
3. Continue to tighten the jackscrew while gently pushing the front panel of the network module into the
slot.
Note
Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.
Step 2 Remove the module from the protective packaging.
Step 3 Remove the blank module from the switch and save it. To remove the blank module, loosen the captive screw
on the module using a screwdriver until it completely disengages from the chassis.

Installing a Network Module
Installing a Network Module

Verify the correct orientation of your module before installing it. Incorrect installation can damage
the module.
Caution
Do not install the network module with connected cables or installed pluggable transceivers. Always
remove any cables and transceiver modules before you install the network module.
Caution
A module interface might become error-disabled when a network module with connected fiber-optic
cables is installed or removed. If an interface is error-disabled, you can reenable the interface by
using the shutdown and no shutdown interface configuration commands.
Caution
Step 4 Position the module face up to install it in the module slot. Slide the module into the slot until the screw makes
contact with the chassis. Fasten the captive screws to secure the network module in place.

Removing a Network Module
The switch complies with EMC, safety, and thermal specifications when a network module is present. If no
uplink ports are required, install a blank network module.
Note
Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface
Do not remove the network module with connected cables or installed pluggable transceiver modules.
Always remove any cables and modules before you remove the network module.

Removing a Network Module

A module interface might become error-disabled when a network module with connected fiber-optic
cables is installed or removed. If an interface is error-disabled, you can reenable the interface by
using the shutdown and no shutdown interface configuration commands.
Caution
Step 2 Disconnect the cables from the pluggable transceiver module.
Step 3 Remove the pluggable transceiver module from the network module.
Step 4 Loosen the captive screws that hold the network module in place until it completely disengages from the
chassis.
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.
Note
Step 5 Carefully slide the network module out of the slot.
Step 6 Install a replacement network module or a blank module in the slot.
Step 7 Place the module that you removed in an antistatic bag or other protective environment.
Installing and Removing Cisco Transceiver Modules
Installing a Cisco Pluggable Transceiver Module
Before you begin
You must have an installed network module to use the transceiver modules. See the switch release notes on
Cisco.com for the list of supported pluggable transceiver modules. Use only supported pluggable transceivers
on the switch. For the latest information about supported transceiver modules, refer to the Cisco Transceiver
Modules Compatibility Information.
For information about installing, removing, cabling, and troubleshooting pluggable transceiver modules, see
the module documentation that shipped with your device.
Observe these precautions:
Class 1 laser product. Statement 1008
Warning
• Do not remove the dust plugs from the pluggable transceiver modules or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports
and cables from contamination and ambient light.
• Removing and installing a pluggable transceiver module can shorten its useful life. Do not remove and
insert any module more often than is necessary.
•To prevent ESD damage, follow your normal board and component handling procedures when connecting
