Usb Type A Port; Uplink Ports - Cisco Catalyst C9200L-48PXG-4X-E Hardware Installation Manual

USB Type A Port

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.
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.

Uplink Ports

The Cisco Catalyst 9200 Series switches support both fixed uplinks and modular uplinks. The C9200 switch
models support modular uplinks with one hot-swappable network module that provides uplink ports to connect
to other devices.
The fixed uplink ports on C9200L switch models support the following types of transceiver modules.
• 4x1G ports that support 1G SFP modules.
• 4x10G ports that support either 1G SFP or 10G SFP+ modules.
• 2x25G ports that support SFP28 modules.
For supported Cisco pluggable transceiver modules (SFP, SFP, SFP28 and QSFP+ modules), refer to the
Cisco Transceiver Modules Compatibility Information at
