Installing a network module
CautionUse 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 generates log messages when you insert or remove a network module with SFP/SFP+ slots.
The switch complies with EMC, safety, and thermal specifications when a network module is present.
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.
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.  CautionVerify the correct orientation of your module before installing it. Incorrect installation can damage the module. CautionDo 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. AttentionA 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 re-enable the interface by using the shutdown and no shutdown interface configuration commands. |
Step 4 | While installing Cisco C9350 network modules, position the module face up to install it in the module slot. Slide the module into the slot until the back of the module faceplate is flush with the switch faceplate. Secure the network module in place by the ejector and the latch.

Installing and removing Cisco transceiver modules
This section describes how to install and remove Cisco transceiver modules.
Removing Cisco-pluggable transceiver modules
Step 1 | Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface. |
Step 2 | Disconnect the cable from the transceiver module. For reattachment, note which cable connector plug is send (TX) and which is receive (RX). |
Step 3 | Insert a dust plug into the optical ports of the transceiver module to keep the optical interfaces clean. |
Step 4 | If the transceiver module has a bale-clasp latch, pull the bale out and down to eject the module. If you cannot use your finger to open the latch, use a small, flat-blade screwdriver or other long, narrow instrument to open it. |
Step 5 | Grasp the transceiver module, and carefully remove it from the slot. |
Step 6 | Place the transceiver module in an antistatic bag or other protective environment. |
Installing and removing power supply modules
Cisco C9350 series smart switches are shipped with preinstalled power supply modules. This section describes how to remove and install a power supply module.
Power supply installation guidelines
Adhere to these guidelines when removing or installing a power supply or fan module.
- Do not force the power supply into the slot. This can damage the pins on the switch if they are not aligned with the module.
- A power supply that is only partially connected to the switch can disrupt the system operation.
- Remove power from the power-supply module before removing or installing the module.
-
The power supply is hot-swappable. In some configurations, such as full PoE+ or power sharing mode, removing a power supply causes powered devices to shut down until the power budget matches the input power of a single power supply. To minimize network interruption, hot swap the power supply under these circumstances:
- the switch is in StackPower mode and sufficient power is available, or
- the switch is powered by other switches in a power stack, and no active backup is in progress.
CautionDo not operate the switch with a power-supply module slot empty. For proper chassis cooling, all module slots must be populated, with either a power supply or a blank module.
Take note of the following safety warnings:
WarningStatement 1024—Ground Conductor
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
WarningStatement 1029—Blank Faceplates and Cover Panels
Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Replacing and installing an AC power supply
Before you begin
WarningStatement 1028—More Than One Power Supply
This unit might have more than one power supply connection. To reduce risk of electric shock, remove all connections to de-energize the unit.
NoteA power supply must always be installed in slot A; it is the default power supply.
Step 1 | Turn off the power at its source. |
Step 2 | Remove the power cord from the power cord retainer. |
Step 3 | Remove the power cord from the power connector. |
Step 4 | Hold the handle on the left side of the power supply module and slide the power supply out.
