2	Status LEDs	5	10/100/1000 PoE+ ports
3	USB mini-Type B (console) port	6	Network module slots

10/100/1000 Ports

The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires twisted pair (UTP) cable of Category 5 or higher. The 10BASE-T traffic can use Category 3 cable or higher.

PoE, PoE+, and Cisco UPoE Ports

The PoE+ and Cisco Universal Power Over Ethernet (Cisco UPoE) ports use the same connectors as described in 10/100/1000 Port Connections, on page 37. They provide:

•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).

•Support for pre-standard Cisco powered devices.

•Support Cisco UPOE powered devices (up to 60W PoE per port). The maximum total PoE power in a 1RU switch is 1800W.

•Configuration for StackPower. When the switch internal power supply module(s) cannot support the total load, StackPower configurations allow the switch to leverage power available from other switches.

Cisco Catalyst 9300 Series Switches Hardware Installation Guide

Product Overview

Management Ports

•Configurable support for Cisco intelligent power management, including enhanced power negotiation, power reservation, and per-port power policing.

See the Power Supply Modules, on page 14 for the power supply matrix that defines the available PoE, PoE+, and Cisco UPOE power per port. The output of the PoE+ or UPOE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.

Management Ports

The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.

•Ethernet management port. See Ethernet Management Port, on page 17.

•RJ-45 console port (EIA/TIA-232). See RJ-45 Console Port, on page 18.

•USB mini-Type B console port (5-pin connector).

The 10/100/1000 Ethernet management port connection uses a standard RJ-45 crossover or straight-through cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the same as the RJ-45 console interface speeds.

If you use the USB mini-Type B console port, the Cisco Windows USB device driver must be installed on any PC connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not require special drivers.

The 4-pin mini-Type B connector resembles the 5-pin mini-Type B connectors. They are not compatible. Use only the 5-pin mini-Type B.

This illustration shows a 5-pin mini-Type B USB port.

Figure 2: USB Mini-Type B Port

With the Cisco Windows USB device driver, you can connect and disconnect the USB cable from the console port without affecting Windows HyperTerminal operations.

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 command-line interface (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. For information on using the CLI to configure the USB console interface, see the Software Configuration Guide.

Cisco Catalyst 9300 Series Switches Hardware Installation Guide

Product Overview

USB Type A Port

The USB Type A port provides access to external USB flash devices (also known as thumb drives or USB keys).

The port supports Cisco USB flash drives with capacities from 128 MB to 8 GB (USB devices with port densities of 128 MB, 256 MB, 1 GB, 4 GB, and 8 GB are supported). When combined with stacking, you can upgrade other switches in the stack from an USB key inserted in any switch within the stack. Cisco IOS software provides standard file system access to the flash device: read, write, erase, and copy, as well as the ability to format the flash device with a FAT file system.

It provides you with the ability 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 flash for the reboot.

Network Modules

The switch supports one hot-swappable network module that provides uplink ports to connect to other devices. The switch should only be operated with either a network module or a blank module installed.

The switch generates logs when you insert or remove a network module with SFP ports.

The following table lists the optional Cisco Catalyst 9300 uplink network modules with 1-Gigabit and 10-Gigabit slots. In addition, Cisco Catalyst 9300 Series switches also support 3850 uplink network modules. For the complete list of supported network modules, see Network Modules Overview, on page 39.

Table 2: Network Modules
Network Module1	Description
C9300-NM-4G	This module has four 1G SFP module slots. Any combination of standard SFP
	modules are supported. SFP+ modules are not supported.
	If you insert an SFP+ module in the 1G network module, the SFP+ module does
	not operate, and the switch logs an error message.
C9300-NM-8X	This module has eight 10G slots with an SFP+ port in each slot. Each port

StackWise Ports

StackWise ports are used to connect switches in StackWise stacking configurations. The switch ships with a 0.5-meter StackWise cable that you can use to connect the StackWise ports. For more information on StackWise cables, see Connecting to the StackWise Ports, on page 34.

Caution Use only approved cables, and connect only to similar Cisco equipment. Equipment might be damaged if connected to nonapproved Cisco cables or equipment.

Power Supply Modules

The switches are powered through one or two internal power supply modules.

Following are the supported power supply modules:

•PWR-C1-350WAC

•PWR-C1-715WAC

•PWR-C1-1100WAC

The switch has two internal power supply module slots. You can use two AC modules or one power supply module and a blank module.

The switch can operate with either one or two 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.

Switch Models, on page 1 shows the default power supply modules that ship with each switch model. All power supply modules (except the blank modules) have internal fans. All switches ship with a blank power supply module in the second power supply slot.

Cisco Catalyst 9300 Series Switches Hardware Installation Guide

Product Overview

Power Supply Modules

Caution Do not operate the switch with one power supply module slot empty. For proper chassis cooling, both power supply module slots must be populated with either a power supply or a blank module.

The 350-W and 715-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1100-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The output voltage range is 51 to 57 V.

Each AC power supply module has a power cord for connection to an AC power outlet. The 1100-W and 715-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord.

StackPower Connector

The following illustration shows the airflow pattern for the switches. The blue arrow shows cool airflow, and the red arrow shows warm airflow.

Figure 6: Switch Airflow Patterns

For information about installing a fan module and fan specifications, see Installing a Fan Module, on page 62.

StackPower Connector

The 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-30CM (0.3-meter cable)

•CAB-SPWR-150CM (1.5-meter cable)

For details about connecting StackPower cables and StackPower guidelines, see Planning a StackPower Stack, on page 27.

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 Ethernet management port or one of the console ports. The 10/100/1000 Ethernet management port is a VPN routing/forwarding (VRF) interface and uses a RJ-45 crossover or straight-through cable.

Note The 10/100/1000 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.

The following table shows the Ethernet management port LED colors and their meanings.
