Cisco C9350 Series Switches - Product Overview
Introduction to Cisco C9350 Series Smart Switches
Cisco C9350 series smart switches are based on the Silicon-One ASIC architecture. The primary position of these switches is in a campus access network. You can also position these switches in campus distribution or collapsed core networks. A distribution network focuses on connecting one or more access layers to the core layer, and a collapsed core network connects multiple distribution layers to other network domains.
Switch models
Cisco C9350 series has eight stock keeping units (SKUs) with native copper downlink ports. The copper downlinks provide Ethernet connectivity using standard copper (RJ-45 connector) ports, typically supporting speeds such as 10/100/1000 Mbps (1G), or up to 10G over copper.
Each SKU has a daughter card that contains the front panel system LEDs, push-buttons, and USB interfaces.

Management ports
The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.
The management port on Cisco C9350 series smart switches are
- Ethernet management port
- RJ-45 console port (EIA/TIA-232), and
- USB Type C console port.
The 10/100/1000/2.5G Ethernet management port connection uses a standard RJ-45 crossover or straight-through cable. The RJ-45 console port connection uses a RJ-45-to-DB-9 female cable. The USB console port connection uses a USB Type C to Type C or Type C to Type A cable. The USB console interface speeds are the same as the RJ-45 console interface speeds.
The console output always goes to both the RJ-45 and the USB console connectors, but the console input is active on only one of the console connectors at any one time. The USB console takes precedence over the RJ-45 console. When a cable is connected into the USB console port, the RJ-45 console port becomes inactive. Conversely, when the USB cable is disconnected from the USB console port, the RJ-45 port becomes active.
You can use the CLI to configure an inactivity timeout which reactivates the RJ-45 console if the USB console has been activated and no input activity has occurred on the USB console for a specified time.
After the USB console deactivates due to inactivity, you cannot use the CLI to reactivate it. Disconnect and reconnect the USB cable to reactivate the USB console.
Multigigabit Ethernet ports
The Multigigabit (mGig) Ethernet ports can be configured to auto-negotiate multiple speeds on switch ports. The ports support100 Mbps, 10 Mbps, 5 Gbps, 2.5 Gbps, and 1 Gbps speeds on Category 5e (Cat5e) cables, and up to 10 Gbps over Category 6 (Cat6) and Category 6A (Cat6A) cables up to a maximum of 100 m. 10Gbps over Cat6 cable is limited for distances up to 55 m. For 10GBASE-T, Cat6a can support up to 100 m when transmitting 10Gbps. Due to the extra bandwidth requirements from the cable, additional limitations exist for best performance. These limitations include, but are not limited to cable reach, cable bundling parameters (tightness, frequency, number of cables, speed with respect to each cable) and cable termination quality.
The 802.3 channel requirements for interoperability typically limit the cable reach to 100 m, but other factors can shorten this reach. In addition, for both Cisco UPOE and Cisco UPOE+ and data integrity, the 100 m total should not include more than 10 m total stranded or patch cable. Therefore, it is assumed that a 100 m link includes a maximum of two 5 m patch cables of the appropriate category, and 90 m of plenum or riser (i.e. solid copper core) cables. Ensure that you follow the TIA guidance on cable dressing.
It is recommended to test the complete link using an appropriate cable tester for 10 Gbps as well as 5 Gbps links. However, even if the link passes cable testing, it is still prone to occasional errors due to aggressors in the bundle, and physical disturbances of the cables. As an example of bundling limitations, for 5 Gbps with cat5e cable, only a total 45 m bundled length is supported; the remaining 55 m should be unbundled. For bundling, follow Cisco Guidelines and Best Practices for the Installation and Maintenance of Data Networking Equipment which recommends the use of Velcro ties every 1 to 2 m for bundled sections.
If you are upgrading the network gear but reusing the existing cable plant, note that at speeds above 2.5 Gbps traditional Cat5e channel specifications do not support full 100 m reach. To ensure 5 Gbps link speeds, we recommend using Cat6a cabling. For more information, see the Whitepaper from NBASE-T alliance, which has now merged with Ethernet Alliance, archived at https://archive.nbaset.ethernetalliance.org/library/white-paper-2/.
Multigigabit ports do not support half duplex mode. Use full duplex mode.
PoE, PoE+, Cisco UPoE, and Cisco UPoE+ ports
A PoE (Power over Ethernet) port is an Ethernet interface that supplies power to connected devices over the same cable used for data transmission. A PoE+ port, also known as IEEE 802.3at, provides higher power to connected devices. It can supply up to 30W of power per port. The PoE port also supports BT 2-pair mode or IEEE 802.3bt (also known as PoE++ or Type 3/4 PoE) to deliver power using only two pairs of wires in an Ethernet cable, as an alternative to its advanced four-pair power delivery.
Universal Power over Ethernet (UPoE) can supply power up to 60W per port to connected devices. UPoE+ enables the powering of high-wattage devices through Ethernet cables; it can provides up to 90W of power per switch interface.
The PoE+, UPoE, and UPoE+ ports use the same connectors as described in 10/100/1000 ports.
This section lists the specifications and features of these ports.
- PoE+ ports: Support for IEEE 802.3af-compliant powered devices (up to 15.4 W PoE per port) and support for IEEE 802.3at-compliant powered devices (up to 30 W PoE+ per port). The maximum total PoE power in a 1RU switch is 1440W.
- Cisco UPoE ports: Support for Type 1 (IEEE 802.3af), Type 2 (IEEE 802.3at), Type 3 (IEEE 802.3bt), and Cisco UPoE powered devices delivering up to 60 W PoE per port. The maximum total PoE power in a 1RU switch is 2880W.
- Cisco UPoE+ ports: Support for Type 1 (IEEE 802.3af), Type 2 (IEEE 802.3at), Type 3 (IEEE 802.3bt), Type 4 (IEEE 802.3bt), and Cisco UPoE powered devices delivering up to 90 W per port. The maximum total PoE power in a 1RU switch is 4320W.
- Configuration for StackPower: When the switch internal power supply modules cannot support the total load, StackPower configurations allow the switch to leverage power available from other switches.
- Configurable support for Cisco intelligent power management, including enhanced power negotiation, power reservation, and per-port power policing.
See the Power supply modules for the power supply matrix that defines the available PoE, PoE+ and Cisco UPoE/UPoE+ power per port. The output of the PoE+ or Cisco UPoE/UPoE+ circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
Optional RFID
The chassis has an optional built-in, front-facing, passive Radio Frequency Identification (RFID) tag that uses Ultra High Frequency (UHF) RFID technology and requires an RFID reader with compatible software. It provides auto-identification capabilities for asset management and tracking. The RFID tags are compatible with the Generation 2 GS1 EPC Global Standard and are ISO 18000-6C compliant. They operate in the 860- to 960-MHz UHF band. For more information, see Radio Frequency Identification (RFID) on Cisco Catalyst 9000 Family Switches White Paper.
For Cisco C9350 series smart switches, the RFID tag is optional. Based on your requirements, you can choose to order the switch with or without an RFID tag at the time of purchase through the PID.
Network modules
The Cisco C9350 series smart switches support replaceable network modules. The switch generates logs when you insert or remove a network module with SFP/SFP+/SFP28 and QSP/QSFP28 ports.
This table lists the optional Cisco C9350 network modules.

USB Type C ports
The USB Type C ports provide access to external USB flash devices (also known as thumb drives or USB keys). The USB Type C port supports flash drives with capacities from 128 MB to 256 GB.
Cisco C9350 switches support both USB-C console port and host port.
-
The USB-C console port
- Serves as a serial console interface for device management.
- Connects a computer or terminal directly to the Cisco device for configuration purposes.
- Enables terminal communication to configure routers, switches, firewalls, or other Cisco network devices.
-
The USB-C host port
- Connects USB devices such as flash drives or hardware tokens.
- Functions as a host to manage connected peripherals.
- Can be used for data transfer, storage expansion, or authentication devices.
In a switch stack, you can upgrade all the switches in the stack with a USB key inserted in any switch member within the stack. Cisco IOS XE software enables the flash drive with standard file system access such as read, write, erase, and copy, and the ability to format the flash device with a File Allocation Table 16 (FAT16) file system. FAT16 file format supports up to 2GB maximum volume.
These ports enable you to automatically upgrade the internal flash with the USB drive's configuration and image for emergency switch recovery using USB auto-upgrade. This feature checks the internal flash for a bootable image and configuration and if either image or the configuration is not available, then the USB drive is checked for boot images and configuration. If the boot image and configuration are available, these are copied to the flash for a reboot.

Ethernet management port
You can connect the switch to a host such as a Windows workstation or a terminal server through the 10/100/1000/2.5 G Ethernet management port or one of the console ports. The 10/100/1000/2.5 G Ethernet management port is a VPN routing and forwarding (VRF) interface and uses a RJ-45 crossover or straight-through cable.
NoteThe 10/100/1000/2.5 G Ethernet management port is an RJ-45 connector that should be connected to a Windows workstation or a terminal server. Do not connect this port to another port in the same switch or to any port within the same switch stack.

RJ-45 console port
The RJ-45 console port is a serial communication port used for device management and configuration. It allows direct access to the device CLI for initial setup, troubleshooting, or recovery when network access is unavailable. The console port transmits serial data rather than Ethernet traffic.
The RJ-45 console port uses the optional RJ-45-to-DB8 female cable physical connector.

Fan modules
The Cisco C9350 series smart switches have three fan modules at the rear of the switch. The fans are hot-swappable and numbered from left to right.
A powered-on switch should always have more than one operational fan. The switch can operate with two operational fans and one nonfunctional fan, but the failed fan should be replaced as soon as possible to avoid a service interruption due to a second fan fault. A switch with one or more fans failed or removed will operate with fans at a faster speed, producing increased sound.

When the fan modules are operating properly, a green LED at the top left corner of the fan assembly (viewed from the rear), is ON. If the fan fails, the LED turns to amber.
The airflow direction is from front-to-rear and side-to-rear. This illustration shows the airflow pattern for the switches. The blue arrow shows cool airflow, and the red arrow shows warm airflow.
For information about installing a fan module and fan specifications, see Installing a fan module.
Power supply modules
An internal power supply module converts external electrical power (either AC or DC) into the precise DC voltages required to operate the switch's internal components, and also provides PoE to connected devices.
The Cisco C9350 series smart switches have three internal power supply module slots. You can use one, two or three power supply modules All empty power supply module slots must be filled with a blank module. By default, these switches ship with one power supply module, and you can purchase more power supply modules when you order the switch or at a later date.
These switches can operate with either one, two, or three active power supply modules or with power supplied by a stack. A switch that is in a StackPower stack can operate with power supplied by other switches in the stack.
CautionA power supply module must be available in the power supply module Slot-A for efficient system cooling.
The following table describes the supported internal power supply modules. In a switch, a mix of Platinum-certified and Titanium-certified power supply modules is supported.

Default power supply modules
All switches ship with a default power supply module. All the power supply modules (except the blank modules) have internal fans.
CautionDo not operate the switch with one power supply module slot empty. Always install a blank module in the empty slot to keep the operating temperature and fan noise lower.
CautionA power supply module must be installed in the power supply module Slot A for efficient system cooling.
This table displays the default power supply module that ships with each switch model.

Power supply modes
Cisco C9350 series smart switches offer redundant and combined configuration modes for power supplies. In both modes, the load is equally distributed among the power supplies.
The system load and number of power supply modules installed determine the power level required by the system from each power supply module, and consequently, the suitable power supply mode. For system power budgeting estimates and to determine power supply requirements, use the Cisco Power Calculator.
To configure a power supply mode, enter the power redundancy-mode command in global configuration mode. If you do not configure a mode, the default mode applies. The default mode is combined mode.
Combined mode
In combined mode, the total power available for the entire chassis is equal to the sum of the output of all the power supplies, multiplied by the share ratio. In combined mode, the power supplies can be of different wattage.
Total combined power = P + (N-1) * P * (share ratio), where
- P is the power output of one PSU
- N is the number of PSUs available on the switch. This can be 1 or 2 or 3.
Redundant N+1 mode
In redundant mode, a given power supply module can either be active, or in a standby mode. In N+1 mode, N is the number of active power supply modules and +1 is the power supply module configured as the standby module.
When you configure the switch with N+1 redundancy, the Cisco IOS XE software ensures that there is a standby power supply available, and that sufficient power is available with the active power supply modules (N). All the power supplies including the active and standby shares the load equally.
However, with a standby power supply installed, the system ensures that the additional output power available with a standby is always reserved for use in case of a failure. If the power supply mode is set to redundant and the total active output power is not sufficient to meet the power requirements, the switch will not enter redundant mode.
StackWise ports
StackWise ports are used to connect switches in StackWise stacking configurations. The switch ships with a 0.5-meter StackWise cable for modular uplink switch models that you can use to connect the StackWise ports. For more information on StackWise cables, see Connecting the StackWise cables.
You can order these StackWise cables from your Cisco sales representative:
- STACK-T1A-50CM Cisco StackWise-1.6T 50 cm stacking cable
- STACK-T1A-1M Cisco StackWise-1.6T 1 m stacking cable spare
- STACK-T1A-3M= Cisco StackWise-1.6T 3 m stacking cable spare
CautionUse only approved cables, and connect only to similar Cisco equipment. Equipment might be damaged if connected to non-approved Cisco cables or equipment.
StackPower connector
The Cisco C9350 switches have a StackPower connector for use with Cisco StackPower cables to configure a switch power stack that includes up to four switches. A switch power stack can be configured in redundant or power-sharing mode.
You can order these StackPower cables from your Cisco sales representative:
- CAB-SPWR-35CM= (0.35-meter cable)
- CAB-SPWR-100CM= (1.0-meter cable)
For details about connecting StackPower cables and StackPower guidelines, see Planning a StackPower stack.
USB 3.0 SSD port
To support the storage needs on the switch, the Cisco C9350 Series Smart Switches provide support for pluggable 120 GB and 240 GB USB 3.0 Solid State Drive (SSD) modules. The USB 3.0 SSD module slot is located at the rear panel of the switch. The storage drive can also be used to save packet captures and trace logs generated by the operating system. The USB 3.0 SSD device is field replaceable.
The USB 3.0 supports an optional 120 GB USB 3.0 SSD (SSD-120G) and 240 GB USB 3.0 SSD (SSD-240G) storage devices. SSD-120G provides an extra 120GB and SSD-240G provides 240 GB of storage for application hosting.
Applications can be hosted in KVM (Kernel-based Virtual Machines), LXC (Linux Containers), or Docker containers. USB 3.0 SSD can also be used to save packet captures, trace logs generated by the operating system, Graceful Insertion and Removal (GIR) snapshots and third-party applications. It can be used simultaneously as a general-purpose storage device and as an app hosting device. You must use only Cisco USB drives; non-Cisco USB drives are not supported.
USB 3.0 SSD is enabled with S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology) functionality to monitor endurance, predict wear-out and carry out various self-tests.
